The results of the 2016–2017 studies are presented. Indicators of the crop structure, productivity and fodder values of chickpea varieties (Privo 1, Volgogradsky 10, Volzhanin) are determined. Different methods of crops treatment with growth stimulants Growth matrix, Megamix Profi, Aminokat + Raikat Development are described. The multifactorial experiment included two options of mineral nutrition (without and with fertilizers N12P52 (factor A); three varieties of chickpeas: “Privo 1”, “Volzhanin”, “Volgogradsky 10” (factor B); two options of vegetation treatment: without and with treatment using Growth Matrix, Megamix Profi, Aminokat + Raikat Development (factor C). The studies have shown that all treatment options f increased productivity of chickpeas and crops quality. The maximum yield was obtained by applying N12P52 for Volzhanin variety treated with Megamix Profi and Aminokat + Raikat Development (2.19 t/ha and 2.16 t/ha with a dry matter of 1.97-1.95 t/ha, digestible protein of 0.36-0.33 t/ ha and an exchange energy yield of 27.10-26.90 GJ/ha, respectively).

Mixed Crops

An important factor in increasing the efficiency of crop diversification in West Kazakhstan and reducing the dependence of crop productivity on weather conditions is the expansion of crops most adapted to unsustainable humidification of plants such as chickpeas, Sudan grass, sorghum, corn and sunflower. One of the ways to increase the productivity of Sudanese grass is to use its mixed crops with chickpeas, sunflower, corn and sorghum. Mixtures due to the best quality indicators of feed provide the maximum yield of feed units and digestible protein. The article presents research data on the study of mixed crops of Sudanese grass with annual crops in the conditions of the 1st dry-steppe zone of Western Kazakhstan. A comparative test of mixed crops by yield from digestible protein area units revealed the most nutritionally valuable mixtures. So, in the research of 2018-2020, the largest yield for digestible protein was obtained on the variant using sunflower for silage mixed with Sudan grass (1.65 c/ha), slightly lower on the versions of using a mixture of Sudan grass and corn for silage (1.58 c/ha) and a mixture of sorghum and Sudan grass for silage (1.55 c/ha).

The article presents the results of scientific research on the growth-stimulating preparations in the pre-sowing treatment of soybean seeds and crops according to the development phases in the foreststeppe zone of the Middle Volga. It contains the results of the 2016-2018 research with an assessment of indicators of plant safety, photosynthetic activity and soybean yield in different treatment options by growth factors. The two-component preparations in pre-sowing seed treatment contribute to better soybean germination up to 78.12%. The pre-sowing treatment of seeds with Risotorphine and Raykat Start preparations forms the maximum leaf area. Comparing three years, we can say that the leaves work more productively in the variants with the use of Risotorphine and Raykat Start in pre-sowing treatment. Weather conditions in 2018 allowed soybean crops to form a high yield. The yield level was in the range of 1.48 - 1.98 t / ha. Inoculation of seeds with Raykat Start followed by crops treatment in the phase of 3-5 leaves and budding allowed achieving maximum yield for all years of research. After treating the seeds with Raykat Start, the maximum grain yield was 1.40 t/ha with a double-treatment of crops by microfertilizing mixture Megamix Profi in a phase of 3-5 leaves and budding.

Fertility reproduction features of southern carbonate chernozems in the conditions of the dry-steppe zone of Northern Kazakhstan (Shortandinsky district of Akmola region) are studied. We studied the changes of humus content in the model micro plot experience. Various variants of the experiment with non-fallow and dump steam without fertilizers, grain crops with different doses of mineral fertilizers, manure, as well as with straw and sideral crops (pea-oat mixture, Donnik) are laid down. The introduction of rotted manure in small doses of 20 t / ha did not provide an increase in humus during crop rotation. When adding 40 and 80 t / ha of manure to the fallow field, it allowed to increase the humus content by 0.24 and 0.18 % of the initial amount. The introduction of sideral steam and perennial grasses into crop rotation enhanced the processes of humification and provided a positive balance of humus. In this version of the experiment, the amount of humus increased by 0.10-0.13 %. The greatest accumulation of organic matter occurred when using melilot: the increase in humus was 0.39 %. Long-term cultivation of permanent wheat crop in one field, even with high doses of mineral fertilizers, does not provide significant reproduction of soil fertility. The application of mineral fertilizers does not contribute to the increase of humus in the soil. The greatest decrease in humus content in southern chernozems is observed in the permanent dump and waste-free pair-0.11 and 0.13% over a 6-year period of observations.

The purpose of the work was to study and identify the main factors aff ecting the quantity and quality of beef produced and sold in the Southern Federal district. A comparative assessment of the growth, development, formation of meat productivity and quality of beef of young animals of beef, dual and dairy breeds with stall-pasture technology and intensive rearing in the industrial complex. Experimental studies have been carried out in farms in the Rostov region. The object of research was cows with calves of Kalmyk, Hereford, Aberdeen-Angus, Russian komolaya, Kazakh White-headed breeds, as well as young animals of the same breeds, in addition, Black-and-White and Swiss breeds. Removable live weight in Hereford steers at 18 months of age was 658,0 kg, and Aberdeen-Angus – 655,2 kg. Domestic steers of Kalmyk were 41–44 kg lower in live weight than their herdmates of two imported breeds. However, with intensive rearing at 18 months of age, steers of Kalmyk breed had a removable live weight of more than 613,7 kg and a carcass weight of 326 kg. The yield of hot carcass was 55,4 %, and the slaughter yield was 58,89 %, which was only 1–2 % lower than the world’s leading beef breeds. It has been found when analyzing the results of boning the half-carcasses of experimental steers that the biggest weight of half-carcasses and the content of muscle and fat tissue in them in absolute terms were in Hereford steers. Steers of Kalmyk breed took the third place in terms of weight of large-sized semi–fi nished products and signifi cantly lost to Aberdeen-Angus herdmates by 7,3 kg or 6,5 %, and Hereford steers by 9,2 kg or 8,3 %. The results obtained prove the expediency of using stallpasture technology in the dry-steppe zone of the Southern Federal district when rearing young animals for beef up to 350–400 kg live weight at 15 months of age and its subsequent intensive rearing under industrial technology, in order to obtain the live weight of more than 570 kg and produce cost-eff ective beef.

The research is devoted to the study of poorly preserved psammophytic variants of meadow steppes in the forest-steppe zone of the Middle Volga Region. It has allowed to define the main stages of re-establishment of vegetational cover and estimate the conservation prospects on the river Ardym in different ecological conditions (geomorphological and edaphyc). It has been established that the re-establishment of psammophytic steppes vegetation occurs in a similar way both on the slopes of the predominantly southern exposition and on watershed surfaces. However, in the absence of anthropogenic effects on watershed surfaces, there is a sylvatization of the vegetation cover resulting in displacement of psammophytic steppes. Only the constantly occurring weak natural erosion processes on the slopes of the predominantly southern exposition contribute to the preservation of these rare communities here. Under intense anthropogenic influence, as well as in the conditions of a significant erosion process, the psammophytic steppes fail to be preserved or replaced by steppe meadows.

Relevance of research. Due to ongoing climate change, almost the entire territory of the Steppe of Ukraine by annual humidity factor belongs to the dry and very dry zones, the relative area of ​​which has increased by 13.2% of the total area of ​​the country compared to the 1960-1990s. At the same time, for today in Ukraine only about 500 thousand hectares are actually irrigated, that is 19% of the potential area. Purpose of research. To determine the patterns and trends of climate change in the western part of the dry Steppe of Ukraine and analyze the economic indicators of production activity in the region as to the variable weather conditions. Research methodology. Climate change was estimated on the basis of Climate Water Balance (CWB) and Hydrothermal Coefficient (HTC) values. The analysis of the economic efficiency of agricultural production was carried out by analyzing the statistical data for Odessa region and for the chosen agricultural enterprise. Research results and conclusions. The use of significant heat supply in the dry Steppe zone is limited by insufficient water supply conditions. In the years of 1991-2016  the average annual rainfall was 480 mm and since the early 2000s there has been a slight increase in that. However, even having 500-550 mm of average annual rainfall that has been observed over the past five years, it is not enough for providing high-yield agricultural production. High thermal regime couses high evaporation that in turn, leads to water supply deficit, which at the end of the growing season amounts to 336-436 mm. According to the HTC index in the region 80% of cases show severe and moderately arid vegetation conditions. At the same time, irrigation area in the region has decreased to a minimum, which has led to the domination of winter cereals and sunflower in the cropping system. Under variable weather conditions, winter wheat yields ranged from 19.4 to 38.5 c/ ha (31.4 c/ha on average) and sunflower - from 12.2 to 21.4 c/ha (17.4 c/ha on average), winter rape - from 13.1 to 20.9 c/ha (18.2 c/ha). It was proved a close direct relationship between the sale price of products of all studied crops and their cost price, as well as the inverse relationship of these indicators with the crop yield. The profitability of winter wheat from 2011 till 2016 ranged from 17 to 153 USD/ha with an average value of 86 USD/ha, winter rape - from 39 to 273 USD/ha with an average value of 166 USD  ha and sunflower - from 116 to 315 USD/ha with an average value of 192 USD/ha. Corn and soybeans have proven to be unprofitable in some years, which obviously explains rather small areas under these crops in the region. Above mentioned demonstrates the high economic instability of agricultural production in changing weather conditions, which is accompanied by significant risks for producers, especially when attracting credits. This situation, in turn, leads to a limited use of intensification means, in particular mineral fertilizers, which promotes agrochemical soil degradation. Under unstable water supply, the magnitude of net profit variation per hectare of arable land in Odessa region is 33-188 USD/ha (111 USD/ha on average). It is possible to increase these indicators by increasing the share of winter rape in the cropping system. With the optimization of the water and air soil regimes as well as crop rotation factor, the profitability of agricultural production in the region can be increased up to 580-600 USD/ha. Similar results were obtained after analyzing the statistical data from the southern regions within the dry steppe zone.
