Abstract. Currently, more than 70% of the agricultural land of our country are in conditions of insufficient moisture. Obtaining high and stable yields is possible only with irrigation using other types of melioration. There are various methods of irrigation, which correspond to the necessary technologies and technical means. The most common method of irrigation in most of the country’s humanitarian zones is sprinkling, which provides the possibility of complex mechanization, reduces the labor intensity of irrigation, improves the use of land and water resources. At the present stage, the transition to landscape-adaptive agriculture in the complex melioration, which meets the requirements of sprinkler irrigation. At the same time, the energy characteristics of modern rain machines and their application do not create ecological balance and maintain the corresponding level of soil fertility. It should be noted such negative phenomena as the formation of liquid and solid runoff, reformation of micro relief and uneven watering. There is a need to create a sprinkler system with optimal parameters of rain and equipping them with modern agricultural production. First of all, it is necessary to develop structures of sprinkler systems that reduce the energy impact on the soil and ensure the necessary uniformity of irrigation water distribution over the surface of the irrigated area. One of the most serious disadvantages of mobile sprinklers is that the sprinklers produce watering of the soil on which the move supporting the wheel, which leads to the formation of the rut and reduce the possibility of other agricultural machines. Thus, improving the quality of sprinkling when using mobile sprinkler machines requires improving the design of sprinkler systems, as well as changing the layout of the sprinkler, which prevents moistening of the soil in the direction of movement in front of the machine. At the same time, changes made to the design of sprinkler machines should not reduce their productivity.

Abstract. The article presents a comparative analysis of the effectiveness of the use of «Tyksel» and «Sat-Som» preparations in order to improve the quality of the skins from animals of the Kalmyk breed. The main reasons for the poor quality of large leather raw materials are inadequate care for young cattle on grazing, non-compliance with the technology of growing and fattening, transportation, slaughter of animals, canning and storage of hides. It was revealed that the mass of paired skins ranged from 30.5 to 33.7 kg, and the bulls’ skins of the experimental groups were heavier than the skins of the control young by 0.5 (1.63%; P> 0.99) and 3.2 kg (10 , 49%; P> 0.999), respectively. The data of the release of the skins of the studied animals were higher than that of the control group, by 0.25 and 0.37%. The use of complex preparations «Tyksel» and «Sat-Som» contributed to the fact that the skins of the calves of the experimental groups had a greater thickness than the control bulls, on the elbow by 2.5 and 7.5%, on the last rib – by 2.3 and 9, 3%, on the ridge – by 3.7 and 7.5%. The results of the evaluation of the skins showed the feasibility of using complex growth-promoting preparations «Tyksel» and «Sat-Som» for the positive correlation of the skin of the experimental bulls.

Abstract. Biologization of agriculture allows to increase the content of basic nutrients in the soil and increase the yield of grain crops in field crop rotations. The following crop rotations were studied: 1) a four-field grain paring plant: black steam – winter wheat – sorghum for grain – oats (control); 2) four-field grain parrying plant: sidereal steam (winter rye for siderat) – winter wheat – sorghum for grain – oats; 3) grain parrot six-field: siderill steam (spring flax on siderat) – winter wheat – sorghum for grain – chickpeas – safflower – oats; 4) eight-field cereal grains: peas – winter wheat – chickpeas – safflower – peas – sorghum for grain – chickpeas – oats. The soil is light chestnut. The average annual precipitation is 339.7 mm. In the control crop rotation, straw and leaf mass of cultivated crops were removed from the field, in other crop rotations all non-commercial part of grain crops remained on the field. The highest content of nitrate nitrogen and mobile phosphorus in the pas-hot layer of the soil to the sowing of winter wheat is provided when cultivated in a four-field crop rotation on the green manure pair with winter rye, respectively, 6.61 and 39.8 mg/kg of absolutely dry soil. The highest content of exchangeable potassium from all the studied crops is provided when sowing oats in a four-field sorghum rotation, where the leaf-stem mass is embedded in the soil – 404.6 mg/kg of soil. The highest average yield of winter wheat was provided during cultivation in four-field crop rotations on black and green with winter rye in pairs, respectively, 2.69 and 2.68 t/ha. The most significant increase in the yield of sorghum grain compared with the control option was observed during cultivation in the four – field crop rotation for winter wheat – 0.28 t/ha. The highest yield of oats was formed during cultivation in the four-field crop rotation for sorghum, leaf mass of which is plowed into the soil – 2.1 t/ ha. The area of application of the recommendations is the dry steppe zone of chestnut subzone of light chestnut soils of the Lower Volga region.

Abstract. In the past two decades, landscape fires have become a significant factor in the dynamics of the state of vegetation. Arid floodplain fires are poorly understood inspite of sufficient attention is paid to forest and steppe fires. The article discusses the results of geoinformation analysis of the fire regime of the northern part of the Volga-Akhtuba floodplain according to the detection of active fire data (thermal point) with MODIS radiometer. The spatial and long-term distribution of thermal points for 2001-2017 has been determined. The periods with the highest (2003, 2006) and the smallest (2001, 2016) number of fires were identified. Hydrothermal conditions influence on the intensity of fires: in high-water years the number of fires is minimal, but in subsequent dry years there are more than 300-400 thermal points. Also burnt areas were mapped using Sentinel-2 color composites. Burnt areas in the floodplain have implicit deciphering signs, so their objective determination is difficult. Work is needed on field calibration of burnt areas and the development of methods for their automatic identification based on remote sensing materials.

Abstract. Satellite monitoring technologies for agricultural land are widely used. The article discusses the technology of satellite monitoring of sown areas based on the calculation of the NDVI area statistics for the contours of individual fields. At the first stage, a layer mask with the borders of the fields of the Oktyabrsky district of the Volgograd region was developed according to interpretation of Sentinel-2 satellite images with a resolution of 10 m in the QGIS program. The average values of the 16-day MODIS NDVI raster for each field on six dates of the vegetation period were calculated with the methods of zonal statistics. The developed geo-information system of the state of sown areas allows to carry out statistical processing of seasonal and long-term data of the vegetation index for each field. This data set is used to separate areas by crop, assess their condition and the influence of various factors on it.

Abstract. Various methods of basic tillage in a three-field crop rotation were studied: black fallow, winter wheat, and spring wheat on the experimental field of the Nizhne-Volzhsky scientific-research institute of agriculture in 2016-2018 in order to identify the most effective resource-saving method of primary tillage on light chestnut soils of the Volgograd region. The best moisture content of the soil at the time of sowing of winter wheat was noted by the chisel treatment with the OCHO-5-40 tool (on average 13.3 mm in the arable layer and 136.8 mm in the meter layer). By cleaning the background with chisel processing retained the advantage in the preservation and rational use of productive moisture. The same option provided the maximum amount of nitrate nitrogen both at the beginning and at the end of the growing season of winter wheat. Indicators of mobile phosphorus and exchangeable potassium were also higher in the variant with deep chisel. The advantage of the variant with the turnover of the soil layer in reducing the amount of weed agrocenosis in winter wheat crops was revealed. The analysis of the structural elements of the harvest of winter wheat was carried out: the number of productive stems, the mass of grain per spike, the mass of thousands of seeds and the yield. In general, the best performance in the structure and yield of winter wheat with different variants of the main tillage provides the background with a deep chisel treatment with an OCHO-5-40 instrument. The highest yield was also noted on the version with chisel loosening – 4.0 t / ha. In the conditions of the dry steppe zone of the Lower Volga region, the best way to tillage is deep processing with agricultural tools OCHO-5-40 to a depth of 0.32-0.35 m.

Abstract. The research was conducted at the experimental field of agricultural research Institute in the years 2012-2018 in the 3-field crop rotation with the following crop rotation: black fallow – winter wheat – spring wheat; black fallow – winter wheat – safflower. The study put options for basic tillage working body OCHO-5-40 in comparison with the treatment of PN-4-35 (control) and the option without the main treatment according to the scheme of experience. Economic evaluation revealed the advantage of deep tillage in chizelevanie OCHO-5-40. The economic efficiency of crop cultivation was estimated by the yield and the cost of obtaining it according to the technological maps. Over the years of research, it was found that the chisel processing, even at a great depth (0.32-0.35 m), can significantly reduce labor and material and monetary costs compared to the dump treatment (0.25-0.27 m) by reducing the specific fuel consumption (up to 60%) and reducing the cost per unit of production, which led to a decrease in costs by 15-30% and an increase in profits by 1 RUB.costs by in 10-15%.

Abstract. Forest plantations in arid regions are the main organizing force that determines the stability of the functioning of transformed ecosystems. In recent decades, the dominance the com-plexes of defoliant insects is leveled by the activation of insignificant structural elements in insect communities, including complexes of leaf-mining insects and their impact on forest plantations. Among the trees and shrubs that are attractive for the development of by leaf-mining insects are highlight the plants of the genus Quercus, Ulmus, Populus and Betula. The population of insect miners in the crowns of these trees is the most diverse. The total abundance of mines here varies on average at the level of 27.2 ÷ 148.5 pcs. / 100 leaves. Complexes of leaf-mining insects in plantings in which the main forest-forming species (Quercus, Ulmus) account for up to 100% are characterized by low diversity (12-7 species). At the same time, the number of mines in crowns reaches a maximum level (50.2 ÷ 190.1 pcs / 100 leaves). The material presented reflects the characteristics of the development of complexes of leaf-mining insects and damaged of leaves on the trees of various genus and the level of the destructive effect of leaf-mining insects on the leaves.

Abstract. One of the most important tasks set for agriculture is to increase the productivity of land, intensification of agriculture and acceleration of socio-economic development of the country. These tasks are facilitated by protective forest plantations (PFP), which improve the environmental conditions of the protected field and increase the yield of crops. Protective forest plantations have a large organic mass, concentrated on relatively small areas, with high durability and stability of environmental impact. They are regulators of bioecological balance in the protected area, eliminate climatic discomfort of the environment. Experts rely on the type of terrain for laying the protective forest strips. It is recommended to arrange such plantings in steppe areas at a distance of 200 meters from each other and in forest steppe and other areas – no more than at a distance of 250 meters from each other. This article describes the technology of cultivation and preparation of soil for shelterbelts in the dry steppe and the semi-desert zones, which can be used in practice.

Abstract. Maize culture is low-demand to predecessors, but the highest productivity can be obtained when it is placed in the crop rotation after winter cereals in soil and climatic conditions of the South-East of the cchz. In the conditions of cchz, a high productivity of maize can be obtained by placing it on the spring cereal predecessors, but under the condition of effective protection of crops against weeds. It is also a good predecessor for spring crops. Studies have found that the most effective basic tillage for corn is a double disk peeling to a depth of 8-10 cm and plowing to a depth of 20-22 … 25-27 cm, depending on the landscape conditions. The highest yield of grain corn was obtained under conditions of moldboard different-depth tillage system in crop rotation, and plowing to a depth of 25-27 cm for maize – 3,92 t/ha, under moldboard system of soil tillage to a depth of 20-22 cm and 25-27 cm – 3,88 t/ha. Increasing the depth of plowing under conditions of moldboard soil cultivation systems and the increased turnover of the stratum e.g. the use of double-level ploughing did not contribute to the increase in its yield. The yield of corn for silage and grain was at the level of conventional plowing. Saturation with flat-cut tillages in combined tillage systems led to a decrease in maize yield in proportion with the increase in their share in crop rotation. The maximum decrease in the yield of corn grain is observed under a non-moldboard multi-depth flat-cutting system of soil cultivation in the crop rotation. In case of N60P60K60 fertilizer application, the greatest efficiency is observed under the combined and multi-depth moldboard tillage systems in crop rotation and under the plowing to a depth of 20-22 cm for corn.

Abstract. The article contains results of researches in conditions of dry steppe zone of chestnut soils. The winter wheat yield forming was studied depending on means of soil preparation and weather conditions. Variants of basic tillage were proposed for study: -a classical ploughing by means of a plow PN-4-35 (control); -a basic tillage by chisel tool OCHO-5-40 with an interval of 0.4 m; 0.8 m; 1.6 m; -a variant without basic tillage. Over the years, studies have found that chisel soil cultivation even to a depth of 0.32-0.35 m allows to reduce the material and monetary costs up to 5-12 % in comparison with moldboard plow soil cultivation (depth of 0.25-0.27 m) by reducing relative fuel consumption (31%). This method increases net income by 1025-2360 RUB per 1 hectare, and also increases the profitability to 29%.

Abstract. Intrusion of invasive species of insects is a process that is hard to control. Economic way of penetration of alien species on the territory of the Russian Federation becomes the main way, which is associated with an increase in turnover of trade and freight, the spread of plant products (sowing and planting materials) on the containers, packaging material, with hand luggage, etc. Naturalization of the adventive species under new conditions does not pass without consequences for biocenosis, and at the same time, an alien species is not always economically dangerous. The absence of natural enemies, the ability to redistribute the energy resources and reproduction skillfully and high variability of the genetic apparatus allows the invasive species to adapt to new conditions. Reduced resistance of plant communities in general and individual plant species in particular provokes a decrease of interspecific and intraspecific competition, which causes a threat to the natural processes of development of biocenoses, contributes to the reduction of biodiversity and increases the possibility of extinction of many species. This applies fully to the population of insects, which are the most important indicator of the state of woody plants.

Abstract. In recent years, the number of dangerous pests of fruit crops, including such harmful as black zlatka, has increased. Damage zlatka trees in the garden and seedlings in the nursery often lead to their death. The most vulnerable to zlatka (Capnodis tenebrionis L.) are stone cultures. For three years, in the experimental production laboratory of fruit crops of the lower Volga research Institute of agriculture by route surveys, as well as monitoring of fruit plantations, in the period from budding to termination of vegetation, with an interval of 4-5 days, the study of the distribution and number of pests was carried out. As a result, it was found that the greatest damage, in the conditions of the Volgograd region, zlatka causes fruit plantations during the ripening period of stone fruit crops (June-July). The most effective way to combat this pest is the treatment of systemic insecticides in the period from the beginning of fruit formation to the end of fruit ripening, and in the nursery – until the end of the growth of shoots.

Abstract. Sudanese grass (Lat. Sorghum drummondii) is an exceptionally drought-resistant crop, it makes good use of the rainfall of the second half of summer and forms a large above-ground mass that is suitable for repeated grazing and mowing. Plant breeders of lower-Volga NIISKh, affiliate of FSC of Agroecology RAS created 9 sorts of Sudanese grass. Despite the success, it should be noted that the created sorts are not perfect enough. Currently, there are many requirements for the sorts: compliance with climatic and soil conditions of cultivation, resistance to stress factors, diseases and pest damage, adaptability to mechanical cultivation, high quality and yield of obtained production. The main methods used in new sorts breeding are manual castration and pollination during the inter-sort hybridization. Self-pollination, free pollination, mass and individual selection. The article presents the results of breeding work consisting of the creation and study of new early-ripening, high-yielding, good-qualitative sort samples of Sudanese grass.

Abstract. There was studied an adaptability of spring barley sorts to extreme weather conditions in the dry-steppe zone of chestnut soils of the Volgograd region. There were used the data from competitive test of sorts for period of 2015-2018. The experiments were carried out on 4 sorts, entered in the register of selection achievements in the lower Volga region and 2 promising sorts bred by the Lower-Volga NIISKh, affiliate of FSC of Agroecology RAS in accordance with field predecessors. Years of research were characterized by considerable contrast of the weather during the growing season of barley: 2015 and 2018 – dry, hydrothermal coefficient 0,3-0,1; 2016 – arid (0,8); 2017 – slightly dry (1,1). The average yield of the sorts ranged from 2,36 t/ha for the standard sort called «Kamyshinsky 23» to 2.60 t/ha for new sorts called «Medicom 696/1132». The most stable sorts according to grain yield is barley «Dmitrievsky 5» and a new sort «Medium 200» – coefficients of variation are 41.8 and 42.3%, and the standard is 51.0%. The coefficient of plasticity is highest in promising sorts «Medium 696/1132» – 1.05% and «Medium 200» – 1.04%, and in the sort «Kamyshinsky 23» – 0.94% respectively. In terms of drought resistance, the studied sorts differed slightly in 2018, the coefficient of yield variation in accordance with sorts was 3.13%. Significant differences were observed in heat resistance. In 2015, high temperatures of up to 40°C reduced the grain content in the ear in the period of the barley ears forming and, as a consequence, the yield. The smallest depression of grain yield from heat- and drought-resistant sorts «Demetrius 5» is 56,3%, «Medium 200» is 57.4%, and from the standard sort «Kamyshinsky 23» is 69,1% respectively.

Abstract. For four years, the productivity and adaptive properties of 15 zoned and promising sorts of spring durum wheat in the Lower Volga region were studied. It was revealed the influence of specific elements of productivity for crop yield, such as productive tillering, number of grains in ear, 1000 grains weight, the safety of the plants at harvesting time. The yield of du-rum wheat is the most strongly dependent on the number of grains per ear and weight of 1000 grains. The correlation between these features and productivity is average. Adaptive properties of the sorts were calculated by the method of L. A. Zhivotkov. According to our data, an adaptability of the sorts was more related to varietal characteristics, especially in the lean years. Therefore, it is necessary to examine the breeding material for adaptability more carefully, in order to prevent losing perspective forms.

Abstract. The article considers the market of winter wheat seeds in the Volgograd region. It was determined that consumer demand for winter wheat seeds are not elastic in price. Demand for winter wheat seeds changes by 5%, with a change in prices. The offer is elastic in price, e.g. if the price changes by a percentage, the offer changes by 20.3%. There are several breeding centers within the winter wheat seed market in the Volgograd Region. It is estimated that the Donskoy Agricultural Research Center (Federal State Budgetary Scientific Institution) has the largest distribution of the sorts with a volume of seeds production of all reproductions of 44.4% the second place (18.8%) is occupied by the Federal State Budget Scientific Institution of Agriculture of the South-East according to winter wheat seed concentration within the market, the third place (16.1%) is occupied by FNC Agroecology RAS. The winter wheat seed market can be described as monopolistic competition, when there are several sellers and buyers within the market, but those are in smaller amount than in case of a perfect competition.

Abstract. Manure is the staple food of many insects in nature, especially Black Solider Fly larvae (Hermetia illucens). Hermetia illucens larvae contribute to the natural utilization of food waste, and as they grow, they become food for many small and large animals, as well as birds and fish. Insects convert residual proteins of manure and other nutrients into biomass, which is a high-quality protein food for animals. Studies have been conducted to understand and use this technique for the disposal of manure. Scientists of in China, Russia, the USA, Mexico, countries of Eastern Europe, Israel, Australia, Central and South America use various methods of processing manure methods, as well as methods of recycling organic waste by converting them into biomass. The accent emphasis has shifted towards the production of fodder feed using insects. This increases the concentration of nutrients in animal feed. Insect larvae reduce the nutrient content of manure by 50-60% or more, absorbing them into themselves, while manure becomes a dry, crumbly substance, it is economically profitable to beneficial when transporting it within over considerable distances (unlike manure). Larvae modify alter the microflora of manure, potentially reducing the number of harmful bacteria. And factually, the larvae themselves are a protein feed additive for animals. In Russia, the methodology and cultivation process for the fly of the Black Solider Fly H. illucens are under development and are not practically not used in wide production. The studies have been conducted to understand and use this technique for manure recycling. Based on the literature and our own data, the features of the content of the Black Solider Fly (Hermetia illucens) in the laboratory culture were studied, basing on the literature and our own data, and this article describes the results of experiments of on the cultivation of a Black Solider Fly from eggs to adults and bioconversion of organic material. The prospects of using the fly within in the agriculture of our zone are considered.

Abstract. The article assesses the impact of light chestnut soil treatments on the accumulation of NPK in plowed fields in the Volgograd region. It is established that the higher content of nutrients in the fields that plowed without turnover of the soil layer, and in the control version in comparison with the lower rates at the surface treatment of the soil in all years of research. The data on the microbiological activity of the soil investigated by the method of linen strips are presented. The advantage of ploughing without turnover of the soil layer before classical treatments on the influence of microbiological activity of the soil was established. Changes in the nutrient regime of the soil under the influence of various meteorological conditions of the year are revealed. The intensity of nutrient accumulation depended on the intensity of precipitation, but virtually all of these indicators in years with hydrothermal coefficient of 0.3-0.5 they did not differ from the indicators in the years with hydrothermal coefficient 0.7. Quantitative change of nutrients in plowed fields is observed for different methods of soil cultivation. For comparison, the article presents the results on the accumulation of NPK and changes in soil moisture in the field with direct sowing and chemical treatment.

Abstract. Intensive farming, coupled with the lack of forestreclamation measures, led to an increase in land degradation processes in the Volgograd Trans-Volga region. The structure of land areas in the Trans-Volga region and determines the degree of their degradation by administrative districts analyzed in the article. It has been established that salinization is the most common form of degradation in the Trans-Volga region, it covers 59.4% of farmland, deflation in second place is 28.2%, and water erosion in the third place is 12.4%. The most saline lands are observed in the Pallasovsky district (328.8 thousand hectares), in Nikolaevsky (108.7 thousand hectares) and Staropoltavsky (107.4 thousand hectares) regions. Agricultural lands of Bykovsky (111.0 thousand hectares) and Staropoltavsky (105.9 thousand hectares) areas are most susceptible to deflation. Weak linear erosion and plane soil erosion were found in Nikolaevsky (72.0 thousand hectares) and Staropoltavsky (55.9 thousand hectares) districts. The use of geographic information technologies in conjunction with the data of remote sensing of the Earth allows to monitor the state of agrolandscapes, identify geographic features and rates of development of degradation processes and identify areas that need urgent anti-degradation measures.

Abstract. The article presents the results of studies of agroclimatic conditions of the dry steppe zone of light chestnut soils of the Gorodishchensky Region of the Volgograd Province. Results of meteorological observations since 1955 are reviewed. The influence of two meteorological elements, wind direction/speed and air temperature is discussed. Gorodishchensky Region is located in the Central drysteppe agro-climatic zone. The article analyzes changes that have occurred since the middle of the last century. Studies have shown that small climatic changes can be analyzed within a single locality based on meteorological statistics. It is found that the average daily air temperature has been gradually increasing at an annual rate of 2.1°C. It is also evident that the wind situation has been deteriorating, which calls for wind protection measures, such as planting of protective forest belts. Examining these data will help solve practical problems related to improving the efficiency of land use and agriculture in general in the Gorodishchensky district. And competent management will help increase not only the productivity of field crops but also the fertility of soils.

Abstract. For the first time for semi-desert landscapes of the Volgograd region, according to the currently dominant characteristics of this territory, a retrospective analysis of botanical research has been carried out. The researches of complexity characterize the semi-desert feature, indicating the presence of a tripartite component. The unique meadow chestnut soils peculiar to micro-depressions create conditions for better moisture supply. They are characterized by increased soil fertility, and provide additional opportunities for increasing the forest cover of drylands. Restoration in the fallow regime of complex soils after long-term violations of agricultural activity brings soil fertility to the zonal, with a correlation coefficient of 0.87. The reliability of the results is confirmed by Student’s t-test (probability 0.0005). The specific features of the plant communities are correlated with micro-depressions, where the best moisturizing conditions explain the presence in grass communities near the depressions of forest species. As the plant communities move away from depressions, the number of steppe species changes upwards, and the number of weed and meadow plants decreases. The dominants in the herbage are the cereals of the family Poaceae, 28 species have been identified. The sodominants are wormwood – 7 species have been identified, characterizing the specificity of the herbage. The peculiarity of this area is the distribution of precipitation over the periods of active vegetation analyzed for the 24-year period. In 29 % of the maximum precipitation falls in the summer (characteristic of the steppe zone), spring – 46 %, which corresponds to the desert zone, the remaining 25 % in the autumn. A retrospective analysis of semi-desert landscapes demonstrated the preservation of the uniqueness of the study area through a century-old period.

Abstract. To date land under protective forest belts is an object of non-movable, on which state property is not delimited. As a result, these objects do not belong to anyone, therefore no one can dispose of them. In this situation no one is obliged to preserve protected forest strips. As a result, there is a serious problem of carrying out restoration activities of these objects associated with the poor condition of protective forest belts. As heads of farms in which territory they are located, have no right to carry out any activity in relation to them, according to article 102 of the forest code of the Russian Federation. As a result, positive aspects of the use of protected forest belts are minimized as a result of ageing and extinction of trees, which adversely affects agriculture. One of the ways to preserve the protective forest strips is to carry out thinning, but first, it is necessary to conduct an inventory of forest belts, in order to obtain taxation data, to conduct the necessary restoration activities. This article presents the results of a study of the current state of the protective forest belt in the village of Troitsk, Mikhailovsky district, Volgograd region. The paper used both traditional and modern methods of studying the technical condition of the forest stand, as well as methods of accounting and determining the taxation indicators of the protective forest belt. According to the results of the study, the author gives an assessment of the state of protective forest plantations and recommendations for improving their condition, which can be used in practice.

Abstract. The article presents the data of the research on the cultivation of spring barley varieties Medicum 139 in the dry steppe zone of the Saratov region. The relatively low yield of spring barley in this area is currently due, on the one hand, to the aridity of the climate, low soil fertility, and on the other hand, the lack of development of adaptive technologies for its cultivation, and most importantly, the lack of new drought -, heat-resistant varieties. To obtain consistently high yields in the subzone of dark chestnut soils of the Saratov region, it is necessary to choose the best zoned varieties with appropriate cultivation technologies, namely: soil treatment, optimal precursors, doses of fertilizers, biologically active preparations. Only the use of a new generation of varieties, zoned for the area, and therefore the most adapted to its climatic conditions, will allow to obtain a grain yield of an average of 3.0-4.0 t/ ha. The article shows the economic efficiency of cultivation of spring barley Medicum 139 in the village of Green Dol Engels district of Saratov region in K(f)X Guber D. A. Research on further improvement of barley cultivation technology is currently relevant, and adapted technologies along with new varieties will contribute to an increase in the gross grain harvest of this valuable crop in the Saratov region.

Abstract. Construction of environmentally safe plant protection in agroforestry is realized on the basis of selection of a complex of regulated factors. The main components of the use of resourcesaving techniques and tools here are: system of multi-pedigree plantings, optimal area fields, natural phytocenoses, increasing soil fertility, reducing pesticide load through the use of environmentally friendly means. The forest-protected field is characterized by a pronounced differentiation of the spatial distribution of insects and phytopathogens, what should be taken into account when carrying out destructive activities. In arid conditions, the density of a number of economically dangerous pests exceeds the economic threshold of harmfulness (1.5-5 times). Under these conditions, the transition to accurate management of plant protection is promising. Special attention should be paid to: local implementation of protective measures; variation of consumption rates chemical preparation of drugs depending on the type and variety of culture; the rational combination of chemical, biological and natural means, taking into account the phytosanitary condition of agrocenosis.

Abstract. The Oilseed production has a big place in the national economy and largely determines the food security of the country and its regions, and compared to other types of commodity crop products, is most effective due to the high selling prices of oilseeds and their products due to the growing demand in the consumer market. In the Russian Federation, oilseeds occupy the third place in terms of agricultural production of plant growing after grain and sugar beet, and second place after grain crops in terms of export of crop production. The country has favorable climatic conditions for the cultivation of oilseeds (sunflower, mustard, etc.) and a sufficiently developed material and technical base for their processing. However, imports of oils of tropical origin in the country remain at a high level. The article discusses the reasons for the use and supply to Russia of vegetable oils of imported origin. The degree of preference in the food markets to domestic vegetable oils of imported vegetable oils has been determined.

Abstract. The article explores the possibility of thermally expanded graphite (TEG) using as a sorbent for removing insoluble and partially soluble petroleum products from water surface. The sorption capacity of TEG in relation to petroleum and petroleum products (gasoline, kerosene, diesel fuel, engine oil, vacuum oil, benzene and phenol) was determined by the gravimetric method and UV spectroscopy. A comparative sorption capacity analysis of the TEG obtained by us and a number of carbon sorbents described in literature was carried out. It was shown that the sorption capacity of the TEG obtained by us is comparable, and in some cases even exceeds the literature data. The results indicate to the possibility of obtained TEG using for liquidation of emergency spills of petroleum products on the surface of reservoirs, treatment of industrial wastewater and natural water sources, used, inter alia, for irrigation of agricultural grounds.

Abstract. The intensification of agricultural production leads to an increase in anthropogenic pressure on agricultural landscapes, which in turn leads to an increase in land degradation, including arable land. Progressive agricultural technologies allow timely identification of degradation foci, taking into account their spatial differentiation, and enable their timely localization. This article introduces the latest data on the studied problem. The use of geoinformation technologies in combination with aerospace information makes it possible to assess the current state of arable land. These technologies provide rapid erosion, deflation, salinization and other types of degradation foci detection that lead to loss of agricultural land fertility. For aerospace analysis of the arable land state, largescale space maps are used, which are created on the high-resolution space images (0.4-1.0 m) basis. As a result of the test site «Nesterkin» analysis, thematic geoinformation cartographic layers of the fields structure, terrain and protective forest stands were compiled. On the basis of arable land carto-graphic spatial analysis, 27 fields have been identified that are protected by forest stands. The minimum area of arable land in the research area is about 16.09 ha, the maximum is 455.73 ha. Five plots are included in the dark chestnut soil contour with a medium-sized humus horizon. Seven plots of arable land with a total area of 1353.66 ha are included in the chestnut soils contour with 25-50% chestnut solonetses with a lowthick humus horizon. The others are located on several soil contours. More than 72% of the arable land area requires anti-erosion measures, since the level of degradation «risk» has been identified in these fields.

Abstract. The article researches the spatial, seasonal and long-term patterns of the burnt-out areas dynamics in the Lower Don floodplain. This area is of great nature conser-vation and economic importance. After the construction of the Tsimlyansk hydroelectric complex, the spawning grounds of semi-anadromous and anadromous fish of the Azov Sea basin are concentrated here. The authors use a long-term data archive on the materials of burned-out areas automated identification based on the MODIS spectroradiometer (Terra and Aqua satellites) for 2001-2019, as well as methods of geoinformation processing. On the basis of spatial analysis and overlay operations, the values of the burned-out areas were determined in twelve major floodplain areas in the lower reaches of the Don. It was shown that the total area burned out during the research period exceeded 150 thousand hectares, which is about half of all the flood-plain lands of the Lower Don. The authors found that most of the burned-out areas fall on August and September, and significant areas in the delta are burned in March and April. It is stated that the highest frequency of fires during the research period was 10 seasons, and more than a quarter of the entire territory was covered by fire two or more times. The developed electronic maps can be used to optimize fire prevention measures in the region under study.

Abstract. The article presents research and analytical material on the sowing structure role in agriculture. The objects of research were indicators of production activity of individual agricultural enterprises in the Volgograd region and their agricultural landscapes. The sowing structure formation with new cultures began in the 60s of the last century with the introduction of corn, sunflower, Sudan grass, grain and fodder sorghum, later chickpeas, Camelina sativa, and is also associated with the achievements of Soviet breeding. In the late 80’s, a balance was achieved in sowings between winter and spring cultures, between cereals, row and forage cultures. Sowings of perennial grasses reached 5-7 % of the arable land. With the market relations advent in the sowing structure, the percentage of more profitable cultures increased, such as sunflower, whose sowings in the region sharply increased to 800-900 thousand hectares, and winter wheat, which began to occupy up to 70-80% of grain crops. Annual forage cultures and perennial grasses have almost disappeared in the sowings. The article shows the dynamics in production and economic indicators changes depending on agricultural technologies in the current field cultures sowing structure. The negative and positive aspects of different technologies using are noted, as well as changes in soil fertility are analyzed. In conclusion, it is stated that the sowing structure for a number of environmental indicators is a factor in the ecological and economic agricultural landscapes balance formation and the organizing link of agricultural technologies themselves.

Abstract. The article is devoted to the detailed analysis of the field training practice final day in soil science, which is an integral part of the educational process in training specialists of ecologists and nature managers. As a research task, the author has identified an attempt to evaluate a new method of active learning through observation and analysis. In order to cause students’ interest to further soils morphological properties study, the first competition on field soils description was held. The method of Buivolova A.Yu., Prokofieva T.V., Kurbanova F.G. was used. The regulations of the international competition were redesigned and adapted to the curriculum of the first year students-ecologists practice. The students’ work was evaluated according to the 100-point system. Despite the fact that no team was close to the maximum score, in general students were better able to describe the soils morphological properties than in the traditional form of practice. As a result of the competition total analysis, both positive and negative aspects of the new active training method were revealed. Thus, the positive aspects include students’ acquaintance with the new Russian and international soils classifications, as well as the forms of description of the soil profile. The application of international practice of Mansell color scale using allowed to minimize errors in the soil color definition, which in the traditional format of practice were quite common. The largest difficulties for students both in the process of the new training method application and in the traditional format caused the soil structure definition, because in the most of methodical manuals for soil science practices there are no illustrative examples of different soil structures and departments, but only a text description or graphical drawings. In conclusion, the author notes that in such competitions the participants show personal responsibility for the final overall result. The author also suggests the possibility of using non-imitation methods in the educational process. The experience gained in the application of the new teaching method during the field training in soil science will undoubtedly be interesting for pedagogy specialists, who teach natural sciences.

Abstract. In the chestnut soils dry-steppe zone arid conditions of the Lower Volga region, the undoubted scientific interest in the soil protective main soil treatment and adaptive zoned varieties of various selection winter wheat, insufficient information about their impact on the soil structural and aggregate composition and the yield of this crop make the chosen research topic relevant. The purpose of the research was to carry out the basic tillage methods comparative assessment for pure fallow and winter wheat varieties of various selections, which allow increasing this crop grain production in the region. The soil on the experimental site is chestnut, heavy loamy, with a content of 2.12% humus in the upper humus-accumulative 0-0.24 m soil layer. For the 2019-2020 agricultural year, 274 mm of precipitation fell. The two-factor experiment scheme included three basic tillage methods (factor A): plowing to the usual depth of 0.2-0.22 m (control), deep chiseling to 0.3-0.32 m and shallow disking to a depth of 0.12-0.14 m, as well as three varieties of winter wheat (factor B): Ermak (St), Kamyshanka 6 and Lilith. The winter wheat cultivation agrotechnics were generally accepted for the research area, except the studied methods of basic tillage and varieties. The winter wheat predecessor was pure fallow. The most agronomically favorable lumpy-grainy soil macrostructure with the lumps size from 0.25 to 10 mm in the arable soil layer was provided for harvesting winter wheat when deep chisel main tillage was carried out with the varieties Kamyshanka 6 and Lilith under clean fallow, respectively 76.3 and 77.5%, the structural coefficient in these variants was 3.22 and 3.44. The highest winter wheat yield was provided in the varieties of Volgograd selection Kamyshanka 6 and Rostov selection Lilith against the deep chisel tillage background, respectively, 4.06 and 4.17 t/ha.

Abstract. Sweet pepper (Capsicum annuum L.) is a valuable vegetable crop, in the conditions of the Volgograd region, it can be grown by seedling in the open ground. The high yields obtaining is possible only with irrigation, which the most ergonomic way is intra soil irrigation (ISI). The feasibility of ISI using and its regime for growing pepper was established when implementing the hypothesis that the planned crop yield (70 kg/ha) depends not only on the amount of water used for irrigation but also on the evenness of its flow into the rhizosphere. The article presents the two-factor experiment results on the ISI regime influence on the sweet pepper yield. Three variants of before irrigation soil moisture: 75- 65% of the least moisture capacity (LMC), 85-75% of LMC, 85% of LMC were tested. In each case, the distance between the ISI humidifiers (1.2 m, 1.4 m, 1.6 m) was an additional factor. It was estimated that the total water consumption has a medium effect (R = 0.52, R2 = 0.28). The planned yield of 70 t/ha can be achieved in the range of total water consumption in 5500-5900 m3 on ha. Getting more yields than planned is possible when the soil moisture content before irrigation is maintained at the level of 85% of LMC and 85–75% of LMC and the distance between the humidifiers is 1.2 and 1.4 m.

Abstract. The introduced woody plants have been successfully used for many years to create protective plantings of various categories including the South of Russia arid zone, the climatic features of which make specific requirements for the tree species selection for landscaping urban areas. Plants of the genus complex Robinia, the natural area of which is confined to similar natural and climatic conditions in the arid zones of North America, are widespread in the protective plantations of the Lower Volga region. In recent years, the specific Robinia phyllophages invasions have been increasingly recorded in Russia, among which the most aggressive is the Obolodiplosis robiniae. In this regard, this research purpose was to study the features of the Robinia quantitative abundance in biotopes with different ecological conditions. The research was carried out during the 2020 field season in protective plantations of various types and categories. According to the research results, it was found that the Robinia quantitative abundance is influenced by a complex of factors – crown density, air humidity, and also the technogenic press level.

Abstract. The article is devoted to the issues of sewage sludge utilization and application in agriculture. The effect of processed sewage sludge used in field studies as a fertilizer-meliorant on the nutrients and organic matter content in the soil, as well as on the yield of safflower dye has been studied in this paper. According to the research results, sewage sludge contains the main elements of nutrition: nitrogen (3.3%), phosphorus (4.27%), potassium (0.31%) and an increased content of organic matter (32%). The received sewage sludge fully meets the requirements of State Standard R 54651-2011 and can be used as a fertilizer for the cultivation of agricultural crops. The data from the soil samples analysis show that the sewage sludge into the soil at doses of 5 and 10 t / ha introduction increased the organic matter content to 2.28 and 2.94%, as well as ammonium and ammonia nitrogen, mobile phosphorus and exchange potassium. The research results showed that for obtaining the high yields it is expedient to use an organic fertilizer-meliorant sewage sludge in the dose of 10 t/ha and chisel tillage tool OCHO-5-40 with the working body “Rancho” to a depth of 0.37-0.40 m with a soil layer turnover of 0.12-0.15 m.

Abstract. Mapping and modeling of agricultural landscapes located in transitional natural zones, one of which is the territory of Maly Syrt, located on the Saratov and Volgograd regions border, is a modern tool for studying the of the natural and territorial complexes functioning conditions features, identifying patterns of changes in their state and determining the spatial location of zones of trouble. Satellite images are a contemporary source of information for forming a spatial database on the agricultural land current state. They are provided mainly in digital form, representing a class of raster digital images – in a certain sense, models, and spatially defined. Such images, when analyzed in specialized computer programs, allow to obtain a large amount of data about the studied territory. The developed mathematical and cartographic models provide the necessary information for determining both the existing characteristics of agricultural landscapes and predicting their changes in the future. The geoinformation systems development relevance for identifying and forecasting the agricultural landscapes state is due to the need to provide the agro-industrial complex with up-to-date spatial information and spatial models that make it possible to solve scientific and applied problems related to inventory, analysis, modeling, forecasting and management of the land resources agricultural use territorial organization.

Abstract. The article is devoted to the actual problem of reducing the arable land productivity in the agricultural production intensification conditions. Agrochemical survey of fields is an important element of the soil fertility monitoring system in both rainfed and irrigated agricultural landscapes. The latest contemporary methods advantage was revealed, using which a soil fertility elements comprehensive analysis of the irrigated area of the farm was carried out on the land use by LLS «Rusproduct-Zavolzhye» example in the Sredneakhtubinskij district of the Volgograd region, located in the light chestnut soils subzone. The research novelty lies in the integration of the satellite images cameral deciphering, their field standardization with the soil sampling points coordinate referencing, laboratory analysis and following geoinformation mapping. According to the soil samples analysis results, it was established that the soils of medium loamy granulometric composition, with a low humus content and low in nitrogen are prevailed in the farm. Fields with increased availability of mobile phosphorus make up 67.8%, with average availability – 26.5%, with high – 5.7%. Soils with an exchangeable potassium high availability make up 84.8%, with a very high availability – 10.7%, with an increased availability – 4.5%. Despite the drip irrigation use, land-use soils are mostly non-saline, with a dense residue (content of water-soluble salts) varying from 0.8 to 0.12%. The water extract pH value varies from 7.35 to 8.87, which corresponds to a slightly alkaline and alkaline reaction. The sulfur content analysis showed that the fields with low availability are 82.2%, with an average – 17.8%. The compiled agrochemical cartograms made it possible to determine the studied lands fertility level more effectively and clearly.

Abstract. The paper presents a method of burned-out areas of non-forest landscapes visual expert de-encryption based on satellite observation data in the river floodplains conditions. The authors carried out a comparative analysis for monitoring the landscapes fire regime methods using the example of the Volga-Akhtuba floodplain. In the work, information products FIRMS for detecting active combustion and MCD64A1 and FireCCI51 for burnt areas have been used. The automated algorithms accuracy assessed based on the burned-out areas identified by high-resolution satellite images from Landsat and Sentinel 2. The analysis revealed that services that have global coverage lose the burned-out areas boundaries accuracy for some types of landscapes at the regional level. Due to the floodplain landscapes geomorphological features, fires here are small in size, elongated, and short in duration. Due to this, visual methods turn out to be more reliable in identifying burned-out areas than automated ones, which can be used for additional verification during expert de-encryption.

Abstract. The cereals grain proteins qualitative and quantitative composition determines the quality and nutritional value of grain, as well as the flour obtained from it for humans. The protein profiles highlighting method should be accurate and at the same time as accessible and fast as possible, for this purpose, the construction of electrophoretic profiles is widely used. On the other hand, protein pattern differences could be used for variety identification and search for their associations with important for breeding phenotypic attributes. A first stage to search protein candidates for use as protein markers is polymorphic proteins detection, which have high variability value between varieties. The purpose of current work is protein patterns difference analysis of durum wheat and spelt varieties grown in the conditions of spring drought by electrophoresis. In 7 varieties of durum wheat, 17 proteins were identified, the content of which differed most significantly between varieties. Protein profiling using two prolamins with molecular weights of 100 and 60 kD allowed us to divide 7 studied varieties into 4 groups. 8 proteins were identified in spelt, the content of which differs greatly between varieties. Moreover, two polypeptides were found in the globulin fraction, which are present in all studied spelt varieties and absent in all durum wheat varieties. Therefore, the obtained results can be used in the further protein markers search of economically valuable properties and durum wheat and spelt varieties identity.

Abstract. The intensive gardens type creation is closely related to the clonal rootstocks use, which contribute to accelerated fruiting, increased productivity due to a denser planting scheme, as well as the planting maintenance convenience. The clonal rootstocks use to produce high-quality planting material for laying intensive gardens is a priority area of horticulture. In this regard, the identification of the method of clonal rootstocks accelerated reproduction by cuttings remains one of the contemporary nursery breeding main tasks. The article presents the comparative study of the cuttings of stone crops clonal rootstocks survival rate data for 2018-2019, depending on the rooting method, as well as the rooted rootstocks survival rate after transplantation into the first field of the nursery. According to the obtained in the course of research experience results, it was found that rooting when using a mist-forming device is higher than rooting with lignified cuttings, but at the same time the rooting with lignified cuttings method is more simple, convenient and cheap. According to the data obtained after planting the rootstocks in the first field of the nursery, it was found that plants rooted with lignified cuttings took root and developed better than plants rooted with green cuttings.

Abstract. Sesquiterpene lactones are one group of substances observed in seeding lettuce (Lactuca sativa) are add a bitter taste. Lettuce breeding was aimed in particular to decrease sesquiterpene lactone content in new varieties in previous years. Recently, beneficial pharmacological activities of these substances were found. The purpose of this mini-review was analysis of current knowledge about lettuce sesquiterpene lactone biological activities and lettuce breeding perspectives. Lactucin, lactucopicrin and 8-deoxylactucin are main lactoines in seeding lettuce. Their exact biosynthesis mechanism in lettuce is not clear, only the stages of precursor compounds synthesis were established. Lactucin and similar lactones have multiple pharmacological activities including antitumor, antiinflammatory, analgetic, sedative and antiparasitic effects. The use of the sesquiterpene lactones quantitative content as biochemical markers has certain significant disadvantages. Possible approaches to the development of a new generation of molecular markers suitable for use in breeding are considered.

Abstract. The winter soft wheat varieties test materials on light chestnut soils of the Volgograd region are presented. The study purpose is to assess the productive and adaptive potential of new promising varieties of winter wheat from various breeding centers. Field experience has been laid at the experimental site of the FSC of agroecology RAS in a nursery located in the dry-steppe zone. The research was carried out according to the generally accepted methods of B. A. Dospekhov. The difference in autumn tillering and intensity of tillering depending on the variety was revealed. Varieties Kamyshanka 3, DF-58-03, Kamyshanka 6, Etud, Doneco and Don Byliny have a high tillering coefficient in the autumn growing season, which indicates the seeding these varieties possibility at a later time of sowing. It is established that intensive tillering in the autumn period does not always contribute to the productive stems preservation. The varieties that have the potential to generate high yields at the expense of a smaller number of productive stems with a larger spike mass are identified: Zhavoronok, Don steppe, Krasa Dona, Victoria 11, Kamyshanka 4, Etud, Stavka, Volodya, Zorro.

Abstract. The article explores the possibilities of analyzing the fire regime of landscapes based on information products based on automated methods for processing Earth remote sensing data from space with a MODIS spectroradiometer (Terra and Aqua satellites). The authors use the data of the active burning sites FIRMS (The Fire Information for Resource Management System) and the burnedout areas MCD64A1 to determine the features of the spread of fire fires in the Volgograd region. The study is based on a geoinformation analysis of a longterm archive (2001-2018) of active burning centers (thermal points) and burned-out areas, including the calculation of thermal points in cells of a regular grid of 10 × 10 km, followed by interpolation using the nearest neighbor method. The possibilities of using data on burned-out areas for the analysis of the fire regime of natural and agricultural landscapes are shown. The article notes that the number of foci of burning in 2010- 2018. it almost halved compared to the period 2001- 2009, the decrease was mainly due to summer fires on agricultural land. The authors identified errors in the detection of burns by automated algorithms, which consist not only of skipping burned areas, but also of mistakenly identifying unburned areas as burnt. As a result, the article states that visual decryption remains the most reliable way of identifying burns, while using MODIS data is justified for additional verification.

Abstract. Land is one of the main elements of national wealth for society, and its rational use significantly affects the development and formation of the country ‘s economy. Irrational use of land is the main problem of the modern state, which directly affects all aspects of economic development. The article deals with the study of land resources, their qualitative and quantitative characteristics, as well as the nature of modern and prospective use of land that will provide the most appropriate and cost- effective use of land in the process of production activities, and at the same time, ensure environmental protection. The study of irrigated and rain-fed arable land plots was conducted within two cadastral blocks 34: 26: 030101 and 34:26:030102 on the basis of geo- information analysis, which made it possible to create a space photo map of the actual use of these lands, as well as to identify violations in the field of land legislation. A management and rational use of land (land resources) can be performed within the framework of land inventory, which is impossible without the use of modern techniques and technologies.

Abstract. Annotation. Under natural and anthropogenic influence, landscapes are transformed. In semi-desert climatic conditions, the processes of land degradation and desertification arise and develop as a result of the transformation. A relevance of research is due to a presence of the processes of degradationon within a large area of land. The method of geoinformation analysis of spatial data based on aerospace surveys was used to identify the areas of landscape degradation. We also used methods of geographic statistical assessment of landscape characteristics and determination a correlation of these characteristics with natural and anthropogenic factors. The novelty lies in the fact that a combined database consisting of cartographic thematic layers and attributes is created for the geoinformation assessment of landscape degradation. The integrated use of this data makes it possible to analyze the digital spatial data that reflects the current state, as well as the attribute information about objects reflected on these maps. The space survey data has clear advantages in terms of regularity, repeatability, territory coverage, and economic efficiency. The images are decrypted using computer methods and programs that provide both visual and automated recognition of objects in the image. The object of the study was the «Kharabali» polygon (Astrakhan region, Kharabali district) with a complex environmental situation, configuration and terrain. The applied geoinfomational methods of analysis helped to determine geomorphological, soil characteristics and spatial distribution of the degraded areas by levels: norm, risk, crisis and disaster with the utmost accuracy.

Abstract. With regard to anti-erosion reclamation, the methodological basis of research is described, and different approaches are considered to account the methods of melt water runoff and soil flushing on slopes. Very diverse agroecological and soil-erosion conditions have historically developed there. For these conditions, the classical method of field experience could not be applied because of the requirements for selecting objects on flat areas with the same soil cover at a distance from forest strips and other forest plantations. An experimental evaluation of methods for soil flushing accounting has shown that the method of water pothole measuring gives inflated results. More accurate results are obtained by the method of determining the turbidity of solid runoff, although it gives understated indicators of soil flushing in some cases. The analysis of all materials indicates the reasonability of parallel using these two methods for determining the flushing and the need to improve the methods of flushing accounting.

Abstract. The role of varieties during the production of winter wheat grain is shown in the article based on the analysis. Among various agricultural practices, they account for 20-25% of crop growth [4]. The study was conducted through consideration of issues related to winter wheat, such as the impact of extreme weather conditions and their consequences (severe winters, droughts, Puccini recondita epiphytosis, and other diseases) on the creation of resistant varieties and the use of hybridization methods. The article draws attention to the fact that the breeding of winter wheat has been carried out since 1993 in the Kamyshin district under conditions of the development and production of the Laboratory of field crops of the NVNIISKH that is a branch of the Federal Scientific Centre of Agroecology of RAS. The article describes the conditions of winter wheat cultivation, which are very difficult in this zone: poor chestnut soils, heavy loam, with stony inclusions with a small humus content of 1.0-1.2%, short spring, hot summer (sometimes the air temperature rises to +40-43 ° C), arid early autumn and severe winter. All this creates great difficulties in case of selection of the winter wheat, so the creation of a variety that is resistant to all stress factors of the external environment is of particular importance here. For recent years, Kamyshin breeders have been able to produce a number of varieties, seven of which are included into the State register of breeding achievements approved for use in the 8th region of the Russian Federation, despite all the adverse conditions during creating the varieties. The last 2 varieties «Elanskaya» and «Memory of Pozhilova» entered in the register in 2020. The tables show the economic and biological properties of the varieties. The advantage of the «Elanskaya» variety in comparison with the best zoned «Don 93» variety is revealed in the following indicators: a greater amount of gluten and protein in the grain, a responsiveness to a high agronomic background, the purpose of the variety in terms of product use is baking. The «Memory of Pozhilova» variety is characterized by a better winter, drought and heat resistance, a relative stability of crops over the years and a tolerance to late sowing periods. In conclusion, it is stated that two promising varieties of winter wheat e.g. «Elanskaya» and «Memory of Pozhilova» were created for the drysteppe and black-earth zones of the Volgograd region as a result of breeding work, and also it is briefly stated that breeders are working not only to increase yields, but also to achieve stability of winter wheat yields.

Abstract. A research is related to the problem of chickpeas growing. Despite the positive qualities of chickpeas, it is not widely distributed on the sown areas in the Russian Federation. The reason is its low competitiveness with weeds, as well as its increased sensitivity to herbicides. The article describes a method for weeds controlling in chickpea crops. The research was carried out in 2015-2018 at the experimental field of the Lower Volga Research Institute which is a branch of the FSC of Agroecology of the Russian Academy of Sciences, located in the zone of chestnut soils (Volgograd region, Gorodishchensky district). The experiments were performed in three versions and in four repetitions. Tank mixtures of herbicides were used. Their effectiveness was determined in terms of the fight against weeds in chickpea crops. The yield was obtained with a profit margin of 15 and 25.6%. The highest economic efficiency was shown by the variant with a tank mixture of herbicides, such as promethrin 750 g / ha + C-metalochlor 786 g / ha. The yield of chickpea beans was 0.71 t / ha in this variant, and 0.45 t/ha in the control without the use of herbicides, respectively. An applying of our recommendations will improve the yield and quality of chickpeas.

Abstract. Amaranthus is an ancient American Indian crop. The earliest information about it is found in the book series «Monuments of literature», published in the 1970s in Russian. In Russia, cultural amaranth has been tested since the first third of the last century. Weed species of Amaranthus were introduced into Russian territory in the 19-20-x centuries and are burdensome weeds in modern agriculture. The high competitive ability of weed amaranths is determined by their biology. The degree of contamination of arable land with wild amaranth seeds largely hinders the development of cultural species. The quality of varieties and the level of seed production of amaranths remains as a problem. The practical experience of growing amaranth is summarized in the Trans-Volga districts of the Volgograd region. It is proposed to develop a preventive set of measures for the destruction of wild amaranths, the development of technology for cultural species cultivating in relation to local conditions and seed production improving of created Amaranthus varieties.

Abstract. Generalizing work devoted to the disclosure of the artificially created forest plantings systems influence that perform protective and reclamation functions. The main research methods are field water-balance studies at experimental runoff-erosion stationaries, with a complex of runoff sites and experimental drainage areas. In the steppe arid zone, with an annual precipitation of 400-450 mm, unproductive annual losses from unprotected forest strips of agrocenoses reach 230-280 mm or 50-60%. The forest cluster has a high inhibitory effect on Aero hydrodynamic flows (winds, snowstorms, dry winds, slope water streams and surface runoff water flows), which reduces their intensity and negative entropic effect on soils and agrocenoses. For the first time, numerical values of wind-blizzard losses sublimation and snow drift-transport during the cold (winter) period in unprotected steppe agro enosis and in forestprotected fields were experimentally revealed. The forest cluster increases the input components of the spring water balance (precipitation, absorption) and reduces expenditure (sublimation, physical evaporation, surface runoff), localizes and reduces erosion, reduces moisture loss for physical evaporation and transpiration by 15-20%. A General scheme of flat reliefhydroerosive self-organization has been developed, the scientific basis of modern synergetic erosiolandscape studies has been developed. The model agroecolandscapes are used to calculate the perspective ratios of the main land (arable land-steppe forest-water-settlements) for the standard gully basin agricultural landscapes optimal reclamation is an effective means for saving the light (protium) water of high value for human health. It is necessary to revive steppe protective afforestation and sustainable landscape agricultural nature management.

This paper presents data from an experiment that began in 2015 on three lysimeters, filled by sand and planted with pine seedlings with different planting rates: 10000 PCs/ha (lysimeter # 2), 15000 PCs/ ha (lysimeter # 5) and 25000 PCs / ha (lysimeter # 6). The novelty of the research consists in obtaining experimental data on the influence of the pine plantations density on the water regime of various granulometric composition soils (sand, sandy loam, loam). The article details the weather conditions of the 2018/19 hydrological year, which allowed us to trace the process of partial resumption of runoff on some models. The water balance was calculated based on precipitation, transpiration, physical evaporation, and outflow of moisture to ground water. As a result of research, it turned out that during spring snowmelt or a long winter thaw, accompanied by liquid atmospheric precipitation, ground runoff can temporarily resume under young plantings with a high proportion of fallen plants or low planting rates. Previously, it was found that runoff stops when the soil moisture content is 2.22% for soils of light granulometric composition and 8.66% for soils of heavy granulometric composition. In conclusion, it is indicated that pine planting at the age of 3 years during summer transpiration strongly drying up the soil. As a result, the water regime on light soils in some years is periodically washed, and on heavy soils it is non-washed.

Abstract. The use of agricultural land as a resource for food production is of great importance for the ensuring food security of the state. Currently, the structure of land use is changing, especially in arid areas. The complexity of the climate, lack of moisture, low fertility and salinity of the soil do not provide conditions for guaranteed cultivation of products, production becomes unprofitable. Long-term unsustainable use of such the land has led to the degradation of arable land, removal of the nutrients, deflation, water erosion and salinization. Sown areas are not cultivated everywhere, overgrown with the herbaceous ruderal vegetation and the shrubs. A General overview of the arid territories on the example of the Caspian lowland shows a significant decrease in the cultivated areas of the rain-fed arable land. The problem is particularly acute in the immediate vicinity of the irrigated areas on saline and saline soils. The research conducted at the “Kolobovka” test polygon, which is representative of the conditions under consideration, showed that more than 5 thousand hectares of arable land were withdrawn from use. A retrospective analysis of satellite images showed that the last attempt to process it was in 2013. That is, for 7 years, the land has not been used as arable land, it is overgrown. In July 2016, a large landscape fire was registered at the landfill, and dry vegetation was burning. The consequences of the fire are visible until 2018. As a result, arable land was not used for its intended purpose. According to cadastral registration data, the land is at the stage of re-registration.

Abstract. Land legislation sets the priority of protection of agricultural lands, their protection from adverse impacts and destruction, and also forms a strategy for their conservation and reproduction, as the main element of national wealth. The value of land resources is determined by their fertility on a specific economic infrastructure and depends on many factors. The article deals with the issues of land accounting, their condition and quality protection of agricultural land on the territory of the Duplyatsky municipal settlement of Novonikolaevsky district of the Volgograd region. The use of geoinformation technologies within the boundaries of the Duplyatsky rural settlement allowed to clarify the boundaries of the localities that make up it, to assess the arable land and determine the soil washout from each site. The total soil washout is 22316.5 t per 4932.9 ha or 4.5 t / ha. Consideration of issues related to the study of the state and quality of agricultural land is aimed at creating a modern and promising use of land, which will ensure the most appropriate and cost-effective use of land.

Abstract. The article presents the seasonal, long-term and spatial patterns of the fire regime of landscapes in the ecotone “Maly Syrt – Caspian Lowland”. The authors use a long-term archive of data on the detection of center of active fires (hotspots) and geoinformation processing methods. On the basis of spatial analysis and samples based on attribute data, arrays of thermal points are formed in the context of seasonal, long-term, landscape features of the region. It has been shown that in most municipalities summer fires prevail on pastures and summer-autumn fires on arable lands predominate. The authors found that the dynamics of the burning behavior of all types of underlying surface and genera of landscapes is characterized by negative skin coefficients of linear trends. The largest decrease in the number of foci of active combustion occurred on arable land. It is stated that in all considered municipal areas there was a decrease in the number of fires in 2010- 2019. in comparison with the first decade of the 21st century: from 25% in the Fedorovsky district to 70% in the Pitersky district of the Saratov region. The developed electronic maps can be used to optimize fire prevention measures in the studied region.

Abstract. In current conditions, due to the regulation of water runoff and anthropogenic changes in the relief of the surface territories of the Volga-Akhtuba floodplain (construction of roads, dams, mounding of recreational areas, etc.), its flooding areas have significantly decreased compared to previous years, when the Volga’s hydrological regime was close to natural. At the same time, the forest-growing properties of soils changed, which led to the formation of new conditions for the existence of the Volga-Akhtuba floodplain forest ecosystems. Areas of the hilly floodplain were almost completely deprived of woody vegetation and partially transferred to the category of non-wooded lands. As a rule, such territories are confined to the beds of rivers, canals, lakes and are subject to afforestation for environmental and economic reasons. According to the results of our research, new updated data have been obtained. Previously in 2006 and 2017-2020. The biological features and ecological conditions of the growth of scots pine on the Volga-Akhtuba floodplain territory were studied, based on the results of these studies, 3 groups of suitability for afforestation with pine were identified: favorable, medium and least favorable. According to the forest management data, it was possible to allocate 2,055 hectares of non-forested lands of the forest fund, but potentially suitable for afforestation with pine crops. Additionally, with the help of decryption, 1401.1 hectares of forest-suitable areas of varying degrees of suitability for growing pine crops were found.

Abstract. The article identifies the problem of innovative and technological support of the agro-industrial complex of Russia and the Volgograd region, presents the existing practice and analysis of the scientific knowledge transfer to agricultural production, the basic concepts of a new mechanism for the knowledge transfer in the form of consulting activities, the experience of its organization in developed countries, the first steps and experience in the formation of an agricultural consulting system in Russia and the Volgograd region in the 90s of the last century, the current state and prospects for the development of the industry. An analytical method was used to study the regional statistics of scientific and information support of the agro-industrial complex, regulatory documents, scientific articles on information technology topics. The presented material is descriptive of the information infrastructure formation stages in the agricultural sector of the Volgograd region. The forecast of the prospects for the development of the industry is indicated. International projects of the 90s (ARIS, etc.) on the organization of the consulting system undoubtedly brought an understanding of the information support importance for the agro-industrial complex, the form of its organization, methods of work and testing in Russian reality. However, the consulting activity did not receive due responsiveness from the consumers of its services, and consequently, it did not provide practitioners with high-quality innovative and technological material. The highest sectoral and regional leadership, and especially the Ministry of Agriculture of the Russian Federation, did not perceive this system as an effective and efficient mechanism for ensuring technological progress in the agricultural sector, and therefore the ICS system was not properly prescribed in the regulatory and legislative framework for regulating and managing the agricultural sector of the economy and did not receive further development. Contemporary agribusiness in Russia meets the needs for innovative products by receiving information from suppliers of machinery, fertilizers, chemical plant protection products, scientific and practical conferences of research institutes, as well as by self-organizing the producers themselves and exchanging experience with demonstrating high results at the production facilities themselves, holding special seminars on innovations, including the work of specialized newspapers and journals.

Abstract. It is known that sewage sludge is a serious ecological problem for the environment, therefore, the issues of their utilization and reuse remain very relevant. The sewage sludge use in agriculture is a common practice, however, the study of its structure and morphology, as well as the study of its moisture-retaining properties is a new and promising direction, since the data obtained will help to more accurately predict the effects of the introduction of such types of “waste”. The research was carried out on the basis of the Federal Scientific Centre of Agroecology of the Russian Academy of Sciences in the soil testing laboratory. Sewage sludge was taken from the treatment facilities of the Volzhsky city. Field research was carried out on the experimental field in the educational research and production center “Gornaya Polyana”. Experimental studies have established that sewage sludge has a high fertilizing value, the amount of total nitrogen in it was 3.3%, phosphorus – 4.27%, potassium – 0.31%, organic matter – 32%. The content of heavy metals in the sediment is within normal limits. Analysis of microphotographs of sewage sludge has shown that it consists of particles of various sizes: from 0.1 to 800 microns, some of the particles are aggregated. The study also found that both meso- and macropores are found in the sediment. It has been proved that the introduction of sediment in various dosages (0, 5, 10 t/ha) against the background of different depth treatments of the soil allowed to significantly increase moisture reserves. The maximum supply of productive moisture was observed during deep tillage with a chisel dump tool with a working organ “Rancho”. The average yield of safflower with the use of chisel treatment and the introduction of sediment at a dose of 10 t/ha increased by 15.3% compared to the option without application.

Abstract. In the Volgograd region conditions, the amount of annual precipitation plays a key role in shaping the yield of agricultural ecosystems. In this regard, it becomes necessary to trace the influence of vegetation on the water balance of pastures on various soils. For this purpose, models of pasture ecosystems on sandy, sandy loam and loamy soils using herbs of the Stavropol selection were created in large-sized lysimeters. The article considers the results of studies of the pasture ecosystems influence on the water balance of soils in lysimetric models. The data on the annual precipitation distribution of the 2020/2021 hydrological year are also presented, which made it possible to trace the process of changing the gravitational flow on lysimetric models. Transpiration coefficients for three simulated pasture ecosystems are given. On lysimeters with sandy loam and loamy filling, about 50% of the incoming and accumulated moisture is spent on transpiration. With a yield of 0.41 t/ha in pasture ecosystems on sandy soils, soil runoff in the first year of growth decreases slightly compared to areas of ungrown sands and the amount of precipitation spent by plants on transpiration is significantly reduced.

Abstract. The article presents the results of the agricultural land degradation spatial analysis on the test site «Osinovskaya Balka» territory. The research site is located on the territory of the Don Ridge in the Surovikinsky district, Volgograd region. The relevance is due to the intensive use of land on the test site territory as agricultural land, which led to the development of soil degradation. Geoinformation mapping and analysis with quantitative determination of areas under degradation carried out based on observations of the Earth’s surface by ground, aviation and space facilities equipped with various types of survey equipment (remote sensing). Such an analysis is carried out to identify the actual characteristics of the agricultural landscapes state, which is the basis for planning agricultural work on the selected territory. Spatial analysis of the test site performed in the geographic information systems QGIS and ENVI, statistical processing of data carried out in the Microsoft Office Excel software. During the implementation of the geoinformation assessment, cartographic layers were developed: an isolinear elevation map, a slope steepness map, a slope exposition map and an agricultural landscape degradation scheme. As a result, it was revealed that the degradation of the selected agricultural landscapes at the test site «Osinovskaya Balka» with an area of 374.8 hectares is at the «Risk» level, the «Norm» and «Crisis» levels occupy 82.0 hectares each. The level of degradation «Disaster» occupies 4.2 hectares (1% of the total area of chosen agricultural land).

The winter hardiness of plants is influenced by many factors, such as agricultural cultivation techniques, variety, rootstock, wintering conditions, climatic conditions of the period of plants transition to a period of deep rest, the duration of the rest period, etc. Physiological changes occurring in the plant cause them to exit the rest period, which affects winter hardiness. In our experiments, the cultivars emerged from a period of deep rest in February and remained in a period of forced rest for two months, plus or minus two days. As a result of artificial cultivation of cultivars in four variants, high resistance of generative buds and woody parts of the plant to frost up to -35°C was established. When modeling the temperature regime in the freezing chamber -5 and -10°C for five days with a further decrease in temperature by 5°C per hour to -20°C for freezing for 8 hours and thawing at 2°C or -2°C, all varietal combinations showed high resistance to early frosts.

Abstract. The article is devoted to the disclosure of the landscape essence of the impact and the naturetransforming role of the vast hydro-reclamation and hydrotechnical cluster (a set of techniques and methods) on the steppe arid natural-geographical zone of Russia environmental factors in the agroecological conservation landscape-synergetic (Dokuchaev’s) nature management. The hydro-reclamation and hydrotechnical landscape cluster is an important part of the impact, management and transformation of negative processes and natural phenomena of the steppe arid zone under the landscape-synergetic (Dokuchaev’s) agricultural nature management methodology. It has a great impact on the catenarybasin land area hydrological, agroecological and erosion regime, can provide 100% retention of atmospheric precipitation from the catchment basin and more productive use of the residual local surface runoff. It is the main means of quickly and reliably stopping the growth of existing ravines, increasing the water-absorbing role of flow-regulating forest strips and bio-productive use of the absorbed runoff with the help of forest-reclamation drainage, which allows purposefully managing (in time and space) the catchment area hydrological regime. Together with other landscape clusters (forest, pasture-hayfield, adaptive-agricultural, etc.), it is possible to additionally involve 20-50 mm of moisture in bio-production and increasing the low-water period runoff of the small river due to the retention of spring flood and storm runoff, and to reduce non-productive losses of annual precipitation from catchment area by 110 – 160 mm or more, increase and stabilize the transformed basin agroecolandscape productivity.

Abstract. The article presents the results of the main geomorphological characteristics (slopes and exposures of slopes) study relative to agricultural land located in the green areas zone of recreational use in the Sovetsky district, according to the functional zoning scheme of the Volgograd city Master Plan. Territorial planning documents may contain data that does not fully reflect the state of the objects that are located on certain sites. Therefore, the problem of including agricultural land in the green areas zone for recreational purposes is urgent. At the same time, in order to plan certain measures to rationalize the land use, it is necessary to analyze the research objects terrain. The author uses data from remote sensing of the Earth, such as the digital terrain model (DTM) SRTM 1 Arcsecond, as well as high-resolution satellite images of the study area. With the help of geoinformation processing, data on the distribution of agricultural land types by exposure points and slope gradations were obtained. The territory was evaluated according to the main geomorphological characteristics. The predominance of a warm group of expositions and weakly-sloping slopes was established, which has a favorable effect on the growing processes of the main agricultural crops. These data can be used in the development of not only a system of arable land rational use in the study area, but also in the planning of their reclamation. A discrepancy was found between the functional zoning content and the actual situation in the place. The obtained data can be used in the proposal to amend the scheme of the Volgograd city territory functional zoning, in particular, to replace the category of functional zone in the zone of green areas for special purposes (agricultural). Also, presumably, when developing green areas on the studying territory, instead of agricultural ones, it is necessary to take into account the steepness of the slope and the exposure for the green spaces planning.

Abstract. The current state of the Kalmykia lands is associated both with climatic conditions caused by low precipitation, high temperatures in the warm season, strong winds that turn into dust storms, and increasing anthropogenic pressure associated with an increase in the number of livestock, especially sheep and goats. Only in the territory of the Kalmykia, the number of sheep and goats exceeded 2.5 million units in 2019, but the drought of 2020 caused a sharp decline in feed stocks on pastures, which led to a decrease in the number of sheep and goats by almost 0.6 million units in February 2021. The purpose of the research was to identify the actual spatial distribution of degradation and desertification in the Justinsky district territory of the Republic of Kalmykia, chosen as the object of research, due to a combination of natural and anthropogenic factors. The of remote sensing data use and geoinformation analysis methods is an important stage in the development of measures to prevent the degradation and desertification of landscapes. Mapping of degradation levels made it possible to obtain new spatial data for the precise localization of sites with different degradation levels and to identify desertification pockets in the study area. As a result of the research, space maps of natural pasture landscapes were developed with the allocation of degradation contours, their areas and geomorphological characteristics were established, and the composition of natural plant communities was revealed.

Abstract. The article considers the daily dynamics of heat exchange between the soil and the surrounding space, depending on the depth of the soil layer. Thermogradient transfer of moisture in the soil, which is an important part of the water supply of plants, is directly related to heat exchange. Data on the temperatures course were obtained using a series of soil thermometers placedon lysimetric models at a depth of 0 to 50 cm with an interval of 10 cm on soils of light and heavy granulometric composition. It was found that when the air temperature changes from 30°C to 16°C, the soil surface releases 638 kcal/m² of heat into the surrounding space, while at a depth of 50 cm this value is 20 kcal/m², that is, it is reduced by more than 30 times. With increasing depth, heat transfer decreases even more, which is why the value of thermogradient moisture transfer in the daily water supply of plants also becomes less essential.

Abstract. This article presents data on the geomorphological analysis of the Bol’shaya Golubaya river catchment area test site, which was performed using the geoinformational system. The study site is located in three districts of the Volgograd region: Ilovlinsky, Kalachevsky and Kletsky. The relevance of the study is that the satellite remote sensing and geographic information system (GIS) use in the landscape studying makes it possible to obtain new data on the agroforestscapes status and plan their use for agricultural work. Geoinformation analysis of the Bol’shaya Golubaya river catchment area makes it possible to identify how the relief affects the agroforestry landscapes process degradation. The relief characteristics were measured using the geoinformation system. Special maps of geomorphological analysis were developed based on the digital relief model (DRM). As a result, it was revealed that the study area is moderately divided, it is dominated by the southern exposure of the slopes (31%), heights from 140 to 160 m occupy 32% of the entire study area. During the analysis, it was found that the catchment area of the Bol’shaya Golubaya river has 7% of the total area with slope angles equal to 5°. The relief profile along the talweg of the Bol’shaya Golubaya river was layed for the studied territory in the software package.

Abstract. Taking into account the climatic, soil and agroecological realities of the South of Russia, a working protocol for clonal micropropagation of representatives of the genera Caragána and Cersis for protective afforestation was developed. The clonal micropropagation process includes 4 stages: the procedure for selecting a donor plant to obtain a well-growing sterile culture, laboratory scaling of meristematic clones, rooting of propagated shoots and growing plants in a greenhouse before planting in open ground. Specific stages were correlated both with the cultural characteristics of plants and with the specifics of their further habitation in the arid zone with practically no human assistance, but in the presence of a high anthropogenic load as a result of adjacent land use. This protocol is especially relevant for the Volgograd region and has a novelty, since for the first time these plant species are used for clonal micropropagation, and the process of their preparation for natural growth is considered, the selected plants can live in arid conditions, without additional introduction of moisture.

Abstract. Despite the wide diversity of varieties, apricot remains one of the most demanding fruit crops for growing in the Volgograd region. At the same time, the popularity and need for apricot fruits make it the most promising crop for cultivation on an industrial scale. The main factor preventing the laying of large areas of its cultivation is the low resistance to sharp temperature fluctuations in the winter and early spring periods. Therefore, apricot varieties adaptability to the conditions of the planned growth place is a limiting factor in the selection of the assortment. The aim of the research is to study the apricot variety adaptive capabilities assortment in the experimental territory of the laboratory of breeding, seed production and nursery production of the FSC of agroecology RAS, located in the Dubovsky district of the Volgograd region. It is important to study promising introduced apricot varieties for the subsequent use of the most adapted ones in amateur and industrial horticulture of the Volgograd region. Assessment of the varieties stability is carried out in the field according to generally accepted methods. These data for 4 years of research show significant differences in the apricot varieties of different geographical origin adaptability to the most harmful stress factors. The preliminary results allow us to identify promising varieties for further study in the industrial garden conditions.

Аннотация. На основании анализа литературных источников и личного опыта автора статьи в области лесоразведения в Калмыкии дана оценка возможности использования культуры смородины золотой в лесной мелиорации земель на территории Ергенинской возвышенности. Естественные насаждения древесно-кустарниковых пород на территории Калмыкии отсутствуют, и республика нуждается в агролесомелиоративной помощи, так как в условиях засушливого климата только ксерофитная древесная растительность служит надежной защитой населенных пунктов, сельскохозяйственных угодий от неблагоприятных экологических факторов. Климатические условия республики формируют довольно сложные лесорастительные условия, особенно за счет таких факторов, как усиленное испарение, вызванное низкой относительной влажностью воздуха и частыми сильными ветрами при малом количестве атмосферных осадков. Все эти факторы не обеспечивают распространения лесных насаждений естественным путем. Это обуславливает низкий процент лесистости, который составляет в среднем по республике 0,2%. Созданные на территории республики лесополосы из древесно-кустарниковых насаждений служат надежным средством в борьбе с суховеями и засухой. Покрытая лесными культурами площадь представляет собой искусственно созданные полосные и мелкомассивные насаждения, разбросанные по полупустынным ландшафтам Ергенинской возвышенности. Наиболее жизнеустойчивой из кустарников в этих условиях является смородина золотая, успешно произрастающая не только на незасоленных, но и сильносолонцеватых светло-каштановых почвах. Установлено, что она является одной из важнейших пород, используемых на современном этапе защитного лесоразведения в Калмыкии. Обосновано и намечено направление дополнительных исследований эффективного использования этой культуры.

Ключевые слова: полупустыня, светло-каштановые почвы, защитное лесоразведение, культура смородины золотой, опыт и перспектива использования.

Abstract. Based on the literary sources analysis and the personal experience of the article author in the field of afforestation in Kalmykia, the possibility of using the culture of golden currant in forest land reclamation on the territory of the Ergeninsky uplands assessment is given. There are no natural stands of tree and shrub species on the territory of Kalmykia, and the republic needs agroforestry assistance, since in a dry climate only xerophytic woody vegetation serves as a reliable protection of settlements and agricultural lands from unfavorable environmental factors. The climatic conditions of the Republic form rather complex forest growing conditions, especially due to factors such as increased evaporation caused by low relative humidity and frequent strong winds with a small amount of atmospheric precipitation. All these factors do not ensure the spread of forest plantations in a natural way. This causes a low percentage of forest cover, which is 0.2% on average in the Republic. The forest belts created on the territory of the Republic from tree and shrub plantations serve as a reliable means in the combating against dry winds and drought. The area covered with forest plantings is an artificially created forest belts and small-massifs plantings scattered across the semi-desert landscapes of the Ergeninsky uplands. The most resilient of the crops in these conditions is the golden currant, which successfully grows not only on unsalted, but also on strongly saline light chestnut soils. It has been established that it is one of the most important species used at the present stage of protective afforestation in Kalmykia. The direction of additional research on the effective use of this species is justified and outlined.

Аннотация. Для снижения риска гибели плодового дерева, в том числе черешни и сливы, необходимо особое внимание уделять технологии выращивания посадочного материала. На качественные показатели выращиваемых саженцев влияет множество факторов, к перечню которых относятся и орошение. При этом в условиях Волгоградской области орошение является одним из ключевых факторов, обеспечивающих получение качественного посадочного материала. От качества посадочного материала зависит многое. Выбор саженца влияет на дальнейший рост, развитие, плодоношение, урожайность и иммунитет будущего дерева. В данной статье представлен анализ влияния различных вариантов капельного полива на качественные характеристики и процентный выход первосортных однолетних саженцев косточковых культур. Схема опыта предусматривала изучение трех вариантов. Лучшие показатели высоты центрального стебля, диаметра шейки и выхода саженцев 1 класса отмечены во втором и третьем вариантах. Их величины были больше, чем в контроле, соответственно на 21 и 17 см, 0,1-0,2 см и 24-32 %. При этом выход первосортных саженцев в третьем варианте превышает второй вариант по культурам на 6 (черешня) и 5 (слива) %.

Аннотация. Валовые сборы зерна ячменя в Волгоградской области не постоянны по годам и зависят в основном от складывающихся погодных условий, которые не стабильны. Присутствуют годы как острозасушливые с повышенными температурами, так и с достаточным увлажнением. Относительно стабилизировать валовые сборы возможно за счёт создания и внедрения в производство пластичных сортов. Цель исследований: на основе анализа урожайности сортов конкурсного сортоиспытания селекции ячменя ФНЦ агроэкологии РАН за 2017 – 2021гг. по показателям вариации урожая, коэффициентам корреляции урожая с ГТК, экологической пластичности, уровню стабильности и стрессоустойчивости отобрать сорта максимально приспособленные к местным погодным условиям. Объектом исследования явились районированные и перспективные сорта ярового ячменя селекции ФНЦ агроэкологии РАН. В результате комплексной оценки выделены сорта Медикум 885, Нутанс 982, Медикум 1059 и Медикум 200, которые являются наиболее адаптивными к местным контрастным погодным условиям. Возделывание их в хозяйствах Волгоградской области позволит относительно стабилизировать валовые сборы зерна ячменя по годам.

Аннотация. Пищевые растения, синтезирующие антоцианы, считаются более полезными для питания человека. В красных сортах салата посевного антоцианы образуются из предшественников, относящихся по химической структуре к флавоноидам. Однако пока точно не установлено, приводит ли расход части флавоноидов для синтеза антоцианов к стимуляции продукции флавоноидов в растениях с красной окраской листьев. Поэтому целью настоящей работы был сравнительный анализ общего содержания фенолов, содержания флавоноидов и антиоксидантной активности у сортов салата посевного с зелеными и красными листьями. В листьях 10 сортов салата (5 красных и 5 зеленых) определялись содержание фенольных соединений и флавоноидов и величины антиоксидантной активности. Анализ полученных данных показал, что часть зеленых и красных сортов могут иметь сходное содержание проанализированных соединений. В то же время при анализе объединенных выборок было показано, что в листьях красных сортов содержание всех проанализированных групп соединений статистически значимо выше, чем в листьях зеленых сортов. Таким образом, наши результаты поддерживают гипотезу о повышенной продукции флавоноидов и фенольных соединений в целом у сортов салата, синтезирующих антоцианы.

Abstract. Food plants synthesizing anthocyanins are considered more useful for human nutrition. In red varieties of lettuce, anthocyanins are formed from precursors that belong to the flavonoids in chemical structure. However, it has not yet been established for sure whether the consumption of some flavonoids for the synthesis of anthocyanins leads to stimulation of flavonoid production in plants with red leaf color. Therefore, the purpose of this work was a comparative analysis of the total content of phenols, the content of flavonoids and antioxidant activity in varieties of lettuce with green and red leaves. In the leaves of 10 lettuce varieties (5 red and 5 green), the content of phenolic compounds and flavonoids and the values of antioxidant activity were determined. The analysis of the obtained data showed that some of the green and red varieties may have similar contents of the analyzed compounds. At the same time, when analyzing the combined samples, it was shown that the content of all analyzed groups of compounds in the leaves of red varieties is statistically significantly higher than in the leaves of green varieties. Thus, our results support the hypothesis of increased flavonoids production and phenolic compounds in general in lettuce synthesizing anthocyanins.

Аннотация. В статье изучено влияние стероидных фитогормонов – брассинолидов на морфогенетические особенности регенерантов некоторых древесно-кустарниковых видов в культуре in vitro. Эпибрассинолид в составе препарата «Эпин-Экстра» оказывает стимулирующее действие на развитие растений. Поэтому добавление данного препарата в питательную среду должно усиливать действие цитокининов и, как следствие, оказывать положительный эффект на ростовые показатели растений-регенерантов. Полученные результаты свидетельствуют об эффективности внесения в питательные среды для древесных культур эпибрассинолида на этапе микроклонального размножения. Ответные реакции исследуемых объектов: Robinia pseudoacacia L., Cotinus coggygria Scop., подвой Cerasus носят индивидуальный характер и зависят от конкретного генотипа. В качестве эксплантов использовали микрочеренки с одной парой пазушных почек. Культивирование проводили на питательных средах с основным составом макро- и микроэлементов по протоколу Мурасиге и Скуга. В качестве основного цитокинина использовали 6-бензилоаминопурин. Растения культивировали на фитостеллажах при 16-ти часовом фотопериоде и температуре 22-24°C. В течение эксперимента фиксировали линейный прирост, коэффициент размножения, а также общее влияние брассиностероидов на развитие растений в культуре in vitro. Добавление в питательную среду эпибрассинолида для размножения в культуре in vitro древесно-кустарниковых видов экономически выгодно и значительно сокращает сроки культивирования и получения максимального коэффициента размножения.

Abstract. The article studies the effect of steroid phytohormones – brassinolides on the morphogenetic features of some tree and shrub species regenerants in “in vitro” culture. Epibrassinolide in the preparation “Epin-Extra” has a stimulating effect on the plants development. Therefore, the addition of this preparation to the nutrient medium should enhance the effect of cytokinins and, as a result, have a positive effect on the growth indicators of regenerating plants. The results obtained indicate the effectiveness of the epibrassinolide introduction into the nutrient medium for tree crops at the stage of microclonal reproduction. The responses of the studied objects: Robinia pseudoacacia L., Cotinus coggygria Scop., Cerasus rootstock are individual and depend on a specific genotype. Micro-rootstocks with one pair of axillary bud were used as explants. Cultivation was carried out on nutrient medium with the basic composition of macro- and microelements according to the Murashige and Skuga protocol. 6-benzyloaminopurine was used as the main cytokinin. The plants were cultivated on phytostellages at a 16-hour photoperiod and a temperature of 22-24°C. During the experiment, linear growth, reproduction coefficient, as well as the total effect of brassinosteroids on the plants development in culture “in vitro” were determined. The addition of epibrassinolide to the nutrient medium for reproduction in “in vitro” culture of tree and shrub species is economically advantageous and significantly reduces the time of cultivation and obtaining the maximum reproduction coefficient.

Аннотация. Несмотря на большие площади, занятые культурой ячменя, актуальным остается повышение его продуктивности, особенно в годы со сложными климатическими условиями. Задача повышения урожайности не нова и решается несколькими способами, основные из которых – это новые урожайные сорта и современные технологии, в основе которых лежит применение удобрений. Однако вопрос влияния различных удобрений на продуктивность различных сортов в определенных условиях произрастания культуры в большинстве случаев остается открытым. В статье представлены результаты изучения влияния дополнительных обработок посевов ярового ячменя в условиях сухостепной зоны светло-каштановых почв Волгоградской области. Опыты проводились по предшественнику – озимая пшеница – на 4-х сортах двух селекционных центров: Медикум 139 и Новониколаевский – ФНЦ агроэкологии РАН; Ратник и Федос – АНЦ «Донской». Полевой опыт заложен на опытном участке ФНЦ агроэкологии РАН в Городищенском районе Волгоградской области. Изучаемые сорта показали существенные различия по продуктивному стеблестою и продуктивности. Особенно существенной была разница на фоне листовых обработок удобрениями и регуляторами роста, что говорит о высокой отзывчивости изучаемых сортов ячменя на дополнительное питание в условиях светло-каштановых почв Волгоградской области. Представленные результаты требуют дальнейшего изучения, но уже сейчас можно говорить о положительном влияние дополнительного питания на повышение продуктивности ярового ячменя.

Abstract. Despite the large areas occupied by barley culture, it remains relevant to increase its productivity, especially in years with difficult weather conditions. The task of increasing yields is not new, and it is solved in several ways, the main of which are new high – yielding varieties and modern technologies based on the use of fertilizers. However, the question of the various fertilizers influence on the different varieties productivity under certain conditions of crop growth in most cases remains open. The article presents the results of studying the effect of spring barley crops additional treatments in the conditions of the dry-steppe zone of light chestnut soils of the Volgograd region. The data of the competitive variety testing for 2021 were used. The experiments were carried out on the predecessor – winter wheat – on 4 varieties of two lecture centers: Medicum 139 and Novonikolaevsky – FSC of Agroecology RAS; Ratnik and Fedos – ANC «Donskoy». The field experiment was laid at the experimental site of the FSC of Agroecology RAS in Gorodishchensky district. The studied varieties showed significant differences in productive stem stand and productivity. The difference was especially significant against the background of leaf treatments with fertilizers and growth regulators, which indicates a high responsiveness of the studied barley varieties to additional nutrition in the light chestnut soils of the Volgograd region conditions. The presented results require additional study, but already now we can talk about the positive effect of additional nutrition on increasing the productivity of spring barley.

Аннотация.  Статья касается экологического аспекта в аграрном производстве, в частности, проблемы повышения урожайности сельскохозяйственных культур при снижении пестицидной нагрузки на растения. В засушливых условиях Нижнего Поволжья изучено влияние способов протравливания семян на всхожесть, энергию прорастания, интенсивность поражения болезнями корневой системы, урожайность сафлора. Впервые разработаны эффективные баковые смеси препаратов с целью снижения пестицидной нагрузки и повышения биологической эффективности против корневых гнилей. Целью настоящих исследований являлось изучение новых способов защиты растений сафлора в интегрированных системах в Волгоградской области. Опыты по исследованию эффективности способов защиты сафлора проводились в 2017- 2019 годах на территории опытного поля ФНЦ агроэкологии РАН, где преимущественно преобладают светло-каштановые почвы с содержанием гумуса 1,2-2,0%, рН=7,8. Проанализированы результаты опытов в четырех вариантах в 4-кратной повторности. Рассмотрены способы защиты сафлора и выявлена высокая эффективность протравливания семян баковой смесью Винцит 1,5 л/т + Фертигрейн Старт 0,5 л/т. По итогам исследований этот вариант был самым рентабельным с урожайностью 1,2 т/га, на контрольном варианте урожайность – 0,8 т/га, на варианте с применением баковой смести (Винцит 1,5 л/т + Азотовит 2,2 л/т + Фосфатовит 2,2 л/т) – 0,9 т/га. Использование данных рекомендаций обеспечит экологическую стабилизацию при производстве сафлора с высокими урожаями и качественной продукцией.

Abstract. The article concerns the ecological aspect in agricultural production, in particular, the problem of increasing crop yields while reducing the pesticide load on plants. In the arid conditions of the Lower Volga region, the influence of seed poisoning methods on germination capacity, germination energy, intensity of root system diseases, safflower yield was studied. For the first time, effective tank mixtures of drugs have been developed in order to reduce the pesticide load and increase the biological effectiveness against root rot. The purpose of this research was to study new ways of protecting safflower plants in integrated systems in the Volgograd region. Experiments on the effectiveness of safflower protection methods were carried out in 2017-2019 on the territory of the experimental field of the FSC of agroecology RAS, where light chestnut soils with a humus content of 1.2-2.0%, pH = 7.8 predominate. The results of experiments in four variants in 4-fold repetition were analyzed. The methods of safflower protection are considered and the high efficiency of seed poisoning with a tank mixture of Vinzit 1.5 l/t + Fertigrain Start 0.5 l/t is revealed. According to the research results, this option was the most cost-effective with a yield of 1.2 t / ha, on the control variant the yield was 0.8 t / ha, on the variant with the use of tank sweep (Vinzite 1.5 l/t + Azotovite 2.2 l/ t + Phosphatovite 2.2 l/t) – 0.9 t/ha. The use of these recommendations will ensure environmental stabilization in the safflower production with high yields and high-quality products.

Аннотация. В статье изложен вклад ученых эрозиоведов ВНИАЛМИ в изучение эрозионно-аккумулятивного гидрологического процесса и создание основ противоэрозионной мелиорации и современных адаптивно-ландшафтных систем земледелия. А.С. Козменко был первым отечественным ученым, положившим начало систематическому исследованию эрозионно-гидрологического процесса и разработке системы мер по его регулированию, а также впервые в мире создал оригинальную теорию рельефообразования. Дальнейшее развитие взглядов А.С. Козменко продолжено его учеником Г.П. Сурмачем. Им выполнены обширные почвенно-эрозионные исследования, дополнена теория рельефообразования А.С. Козменко, дана теория формирования серых лесных почв и черноземов в лесостепи, разработана новая классификация почв по степени смытости. Развитие теории Г.П. Сурмача продолжили его ученики – Е.А. Гаршинев, В.П. Борец, А.Т. Барабанов, В.И. Панов, А.И. Петелько. Были уточнены условия формирования эрозионно-аккумулятивных форм рельефа; разработана логико-графическая схема эволюции склонов в ходе эрозионно-аккумулятивного процесса, разработана схема самоорганизации равнинного рельефа; созданы научные основы современного синергетического эрозиоландшафтоведения, рассчитаны оптимальные соотношения основных угодий (пашни-степи-леса-воды-поселений); выявлена связь стока талых вод с запасами воды в снеге и почве, глубиной ее промерзания и продолжительностью снеготаяния на юге ЦРНЗ, в ЦЧО и Поволжье; сформулирован закон лимитирующих факторов поверхностного стока талых вод; выдвинута и обоснована концепция «ледяного экрана», формирующегося на границе талого и мерзлого слоев почвы, который играет важнейшую роль в эрозионно-гидрологическом процессе. Таким образом, вековые исследования в области противоэрозионной мелиорации получили достойное развитие и являются сейчас базой для эрозионнобезопасного высокопродуктивного земледелия на основе адаптивно-ландшафтного обустройства территории и создания агролесомелиоративного экологического каркаса.

Abstract. The article presents the erosion scientist’s from VNIALMI input in the study of erosion-accumulative hydrological process and the creation of foundations of anti-erosion reclamation and contemporary adaptivelandscape farming systems. A.S. Kozmenko was the first Russian scientist, who initiated a systematic study of the erosion-hydrological process and the development of anaction system for its regulation, as well as the first in the world created an original theory of relief formation. Further development of A.S. Kozmenko’s views was continued by his student G.P. Surmach. He carried out comprehensive soil-erosion studies, added A.S. Kozmenko’s theory of relief formation, gave a theory of the formation of gray forest soils and chernozems in the forest-steppe, developed a new classification of soils by degree of washing away. Development of G.P. Surmach theory was continued by his students – E.A. Garshinyov, V.P. Borets, A.T. Barabanov, V.I. Panov, A.I. Petel’ko. The conditions of erosion-accumulative landforms formation were clarified; a logical-graphical scheme of slope evolution during the erosion-accumulative process was developed, a scheme of plain relief self-organization was developed; scientific foundations of contemporary synergetic erosion-landscape science were created, optimal ratios of major land-use (arable-steppe-forestwater-settlements) were calculated; the relationship between meltwater runoff and water reserves in snow and soil, the depth of its freezing and the duration of snowmelt in the south of the Central regions of the non-chernozem zone, the Central chernozem region and the Volga region was revealed; the law of surface meltwater runoff limiting factors was formulated; the concept of «ice screen», formed at the border of thawed and frozen soil layers, which plays the most important role in the erosion-hydrological process was proposed and substantiated. Thus, centuries-old studies in the field of anti-erosion reclamation have received a worthy development and are now the basis for erosion-safe high-productive farming on the basis of adaptive landscape arrangement of the territory and creation of agroforestry-ameliorative ecological framework.

Изначально плоский осадочный равнинный рельеф суши самоорганизовывается в пересечённый эрозионный рельеф в виде территориально локализованных рельефо-ландшафтных образований или фрактально-иерархических целостностей – суходольно-речных водосборов. Данная статья посвящена раскрытию этой сложной темы с позиций синергетической парадигмы (принципов и законов самоорганизации сложных нелинейных открытых природных систем). Каждая открытая сложная система (в данном случае анализируются водосборные бассейны) – это локализованные, изолированные друг от друга водораздельными границами, но взаимосвязанные воедино дренирующими водотоками и реками водосборные бассейны от микроводосбора маленького ручейка до гипергигантских водосборов больших и великих рек. Впервые в отечественной и мировой литературе показана эрозионная самоорганизация склоново-бассейнового равнинного рельефа как процессы с обострением в двух режимах – в LS-режиме и в HS-режиме (по С.П. Курдюмову и Г.Г. Малинецкому). Эти процессы открывают возможность математического доказательства самоорганизации на прямых склонах-гиперкатенах первичных больших водосборов с руслом в середине. В статье с позиций самоорганизации-синергетики дана фрактально-иерархическая типизация всех водосборных бассейнов, главных, обязательных элементов самоорганизованного эрозионного рельефа или земельно-эрозионных фондов (водораздельные и приводораздельные равнинные земли, склоны, присетевые крутосклонные земли, земли суходольного и речного гидрографического фонда, склоновые катены и агроэкокатены, смытые земли, линейные промоины, размывы и овраги, суходольные русла и водотоки, масштабная иерархия равнинных рек, речных пойм). Даны их краткие пространственно-временные, функциональные и хозяйственные характеристики с обеспечением экологической, гидрологической и эрозионной безопасности.

Ключевые слова: рельеф, самоорганизация, эрозия, синергетика, водосборные бассейны, типизация эрозионного рельефа, земельные фонды

Abstract. The continuous relief-forming process occurs as a result of a long evolution and under the influence of powerful exogenous-endogenous system-forming forces of nature and man. Initially, the flat sedimentary plain relief of the land is self-organized into an intersected erosive relief, in the form of geographically localized relief-landscape formations or fractal hierarchical wholes – dry valley-river catchments. This article is devoted to the disclosure of this complex topic from the standpoint of the synergetic paradigm (principles and laws of complex nonlinear open natural systems self-organization). Each open complex system (in this case, catchment basins are analyzed) consists from catchment basins are localized, isolated from each other by watershed boundaries, but inter connected together by draining watercourses and rivers, from the micro-catchment of a small stream to the hypergiant catchments of large and great rivers. For the first time in the native and world literature, the hydro erosive self-organization of the slope-basin plain relief is shown as aggravation processes in two modes – in the LS-mode and HS-mode (according to S. P. Kurdyumov and G. G. Malinetsky). These processes open up the possibility of mathematical proof of selforganization on straight slopes-hypercathenes of primary large catchments with a riverbed in the middle. In the article a fractal-hierarchical typification of all catchment basins, the main mandatory elements of a self-organized erosive relief or land-erosion funds (watersheds and near-watersheds flat lands, slopes, middle part of steeply sloped lands, lands of the river hydrographic and dryvalley fund, slope catenes and agrocatenes, washed-out lands, linear washouts, ravines, dryvalleycanals and watercourses, large-scale hierarchy of flat rivers, river floodplains) is given from the standpoint of self-organization-synergetics. Their brief spatial-temporal, functional and environmentaleconomic characteristics are given with the provision of environmental, hydrological and erosion safety.

Аннотация. Устойчивость лесопастбищ в изменившихся климатических условиях привлекает все больше внимания в связи с нарастанием антропогенной нагрузки на пастбищные угодья и увеличением процессов опустынивания. Объектами исследования являлись очаги опустынивания на Черных землях Калмыкии. Изучены сукцессии растительного покрова восстановленных пастбищ, биоразнообразие, структура фитоценозов и фитопродуктивность созданных лесопастбищ. Определена возможность создания очагов инспермации в свежемелиорированных очагах дефляции и сезонная динамика развития видового состава и биомассы растительного покрова в «потухших» очагах дефляции на пастбищах. Установлено, что при сукцессии прогрессивного типа видовой состав восстановленных пастбищ с присутствием древесно-кустарникового яруса достаточно стабильный. Кустарниковый ярус достаточно устойчив в возрасте 30-35 лет даже в крайне засушливых условиях. Под защитой кустарников активизируется формирование травянистого яруса, а устойчивость и продуктивность фитоценозов поддерживает самосев. Мониторинг сукцессий растительного покрова в «потухших» очагах дефляции на Черных землях Калмыкии показал, что долговечные и продуктивные кормовые угодья сформировались при комплексной мелиорации очагов опустынивания, где применялись древесно-кустарниковые и травянистые растения.

Abstract. The forest pastures steadiness in the changed climatic conditions attracts more and more attention nowadays due to the increasing anthropogenic pressure on pasture lands and due to the increasing desertification processes. The research objects were the centers of desertification in the Black Lands of Kalmykia. The vegetation covers succession in the restored pastures, biodiversity, the phytocenoses structure and the created pastures phytoproductivity were examined. The possibility of creating inspermation centers in fresh reclaimed deflation centers and the seasonal species composition dynamics and vegetation cover biomass in «extinct» deflation centers on pastures are determined. It has been established that in succession of progression type the species composition of rehabilitated pastures with the presence of a tree-shrub layer is quite stable. The shrub layer is quite stable at the age of 30-35 years even in extremely arid conditions. The grassy layer formation is intensified and the stability and productivity of phytocenoses supports self-seeding under the protection of shrubs. The vegetation cover successions monitoring in the «extinct» deflation centers in the Black Lands of Kalmykia showed that long-lasting and productive feedstocks were formed during the complex reclamation of desertification centers where tree-shrub and herbaceous plants had been used.

Аннотация. Актуальность исследований обусловлена тем, что орошаемые земли в аридных ландшафтах являются составляющей, позволяющей получать гарантированную продукцию независимо от наличия или отсутствия осадков. Сложившаяся структура орошаемых земель базируется на исследованиях, проведенных при формировании политики экстенсивного развития сельскохозяйственного производства. В результате недостаточной предпроектной подготовки часто создавались системы орошения на землях, не отвечающих требованиям сохранения плодородия почв в условиях орошения. Результатом такой работы являлась неэффективность орошения, связанная с большими экономическими затратами, вызванными потерями поливной воды в открытых системах, потерей плодородия почв за счет засоления и дегумификации, загрязнение окружающей среды. Объектами исследований являлись территории в полупустынной природной зоне. Новизна исследований обусловлена новыми знаниями, полученными в результате геоинформационного анализа территории. Цель исследований – получение пространственных геостатистических характеристик участков орошения, отражающих особенности их положения, размещения в рельефе и определение их координат на основе геоинформационных технологий, геоморфологических особенностей каждого орошаемого участка и данных дистанционного зондирования Земли. Использовалась методология геоинформационного анализа территорий по космоснимкам и по данным цифровых моделей рельефа. В результате исследований определены точные координаты центров орошаемых участков, их геометрия, площади экспозиции на территории исследований, а также карты их пространственного распределения. Геоморфологические характеристики, полученные в ходе исследований, дают возможность провести предварительную оценку перспективности использ�
