The performance of the set tasks for the production of the necessary volumes of grain is possible only on the basis of a scientific-based approach to the development of agricultural technologies on a systematic basis. Research aim: to evaluate the effectiveness of methods of biologization of crop rotation links with winter wheat at the expense of grain legumes and organomineral fertilizer systems in conditions of forest-steppe zone of the Volga region. The research was carried out in years long stationary field trial of the department of agriculture, crop production and breeding of FSBEI HE Ulyanovsk SAU in 4-6-month field crop rotations. The objects of study were of crop rotation links with winter wheat: 1) complete fallow-winter wheat; 2) peas - winter wheat; 3) Lupin - winter wheat; 4) Lupin + peas - winter wheat. In the structure of land use, there is still a high share of complete fallow, which has negative environmental consequences. The main reason for the introduction of complete fallows is the preservation of moisture for seeding winter crops. However, our research shows that when replacing complete fallows to grain legumes (peas, white lupine), 23.0-25.0 mm of productive moisture accumulates in the soil before seeding winter wheat, which, if agrotechnical requirements are met, allows you to get seedlings and sufficient development of winter wheat in the autumn period. Despite the higher yield of winter wheat by complete fallow, the productivity of links with legumes was higher. The inclusion of grain legumes in crop rotations as steam-generating crops can be used to eliminate the negative effects of complete fallow. The results obtained allow us to recommend combined tillage that includes soil loosening for grain legumes and surface tillage for winter wheat, as well as to use the organomineral fertilizer system straw + NPK, while the doses of mineral fertilizers are calculated on the planned yield of grain legumes of 2.5-3.0 t/ha and winter wheat - 4.5 t/ha.

Yield Increase

The article presents results of studies of comparative productivity and cultivation economic efficiency of soybeans, peas, lupine and chickpeas, depending on main tillage systems in crop rotation and the level of plant protection from harmful organisms. Grain legumes are capable of forming a seed yield of 2.0 t / ha in the conditions of the forest-steppe zone of the Volga region. Three-year experimental studies have shown that the studied leguminous crops can be arranged in the following row according to the yield level: peas - 2.51 t / ha> lupine - 2.12 t / ha> chickpea –2.11 t / ha> soybean - 2.10 t / ha. Evaluation of the effect of soil tillage in cultivation of grain legumes showed a significant yield increase by plowing for 25-27 cm in comparison with tillage for 12-14 cm for all the studied crops, a yield increase for adaptive-integrated plant protection was also noted in comparison with minimum protection (protection only against weeds). Studies show that lupine crops had an advantage in protein content, its yield is from 533 to 802 kg / ha, as for soybeans, protein yield was 449-666 kg / ha, peas - 430-521 kg / ha, and chickpeas - 346-486 kg / ha with the advantage of the mentioned variants. A higher conditional net income was obtained on soybeans (31555-44584 rubles / ha) and chickpeas (27777-40037 rubles / ha), especially on combined tillage in crop rotation. Plant protection systems had an equal impact on economic efficiency of their cultivation; in some variants, adaptively integrated plant protection was less effective

Results of researches of efficiency in short crop rotation with busy steam are given in this article. Researches were conducted in the Omsk district of the Omsk region on typical black soil, with the maintenance of humus of 6.7% (in a layer of earth of 0-30 cm).  Cultivation of field cultures against the background of application of means of chemicalixation was carried out in a crop rotation the occupied steam (green manure) – wheat – barley – oats. During the conducted researches the quantity and dynamics of moisture, the maintenance of the main macrocells in the soil, and efficiency of all crop rotation was defined. The received results allow to draw a conclusion that in a crop rotation with busy steam and four fields at application of means of chemicalixation the increase of a harvest of the first wheat for 45.2%, barley repeatedly 31.5% and oats for 9.9% is noted. Application of fertilizers, at the rate of N30P30 on 1 hectare of an arable land, and herbicides, provided increase in productivity grain on 0.53 t/hectare, an exit of grain of 0.44 t/hectare, and feed-protein units to 1.29 t/hectare. The resulting materials can be used in the development of crop rotations schemes for forest-steppe of Western Siberia.

The article considers the practical aspects of ensuring the preservation of natural ecosystems based on the use of organic farming technologies. It presents the results of research in the forest-steppe zone of the Baikal region for 2011-2018. On the basis of the phytosanitary state of crops studying analysis, it was found that the correct alternation of crops in crop rotation suppresses the level of weeds, thereby not affecting the productivity of agricultural crops. The paper reveals the characteristics of agrophysical and water properties of gray forest soil, the influence of forage crop rotations with meadow clover on the yield of cultivated crops. According to the research results, the authors found that overseeding of legumes in the fields of forage crop rotations increases the average productivity by 16.6% in comparison with the control option. The influence of the aftereffect of perennial legumes in crop rotations increases the yield of grain fodder and silage crops by 20-31.8%. The crop rotation with two fields of meadow clover (crop rotation No. 3) was determined to be the best for all indicators.

The Impact

The article presents the results of studies conducted in 2004-2010 at the experimental plot in the forest-steppe Volga region. The research investigated the impact of traditional (average) and differentiated use of mineral fertilizers in the field crop rotation (winter wheat (reconnaissance sowing) – spring wheat ‒ annual grass – spring barley – bare fallow– winter wheat – spring wheat) on the change of agrochemical properties of leached chernozem. It was established that the six-year use of fertilizers contributed to the improvement of the main indicators of top soil fertility regardless of application technology. On average, in 15 sectors (plots) of each variant, the content of mobile phosphorus per rotation of crop rotation increased with differentiated fertilization by 15.9%, potassium – by 15%, and in the traditional one – by 4.8 and 16.7% respectively, (control of 100.8 and 116.2 mg/kg of soil, respectively). In sectors where no fertilizer was applied, the content of mobile elements decreased by 2-7%. The nitrogen content in the soil directly depended on the timing of sampling and the amount of moisture in the soil, so it was difficult to track its change. The difference in the accumulation of mineral nitrogen between the technologies of fertilizer application was not observed. For organic matter in all variants of the experience over the years of research there was a decrease in the indicator. This was more noticeable in the control, where the value decreased by 2.7%. Here, the value of soil acidity increased by 0.12 units and became 4.7. In variants with fertilizers soil acidity remained the same (4.6-4.7). In general, the differentiated use of mineral fertilizers did not have a negative influence on the agrochemical composition of leached chernozem. There was a gradual equalization of soil fertility due to the residual amounts of phosphorus and potassium on low-fertile plots and some reduction of mobile elements in zones with high content.

In the results of research are presented the regularities of the formation of cenoses of segetal vegetation in field crops, in particular, corn for grain and soybeans, with adaptive tillage systems in the Forest-Steppe zone of Ukraine in order to develop effective, environmentally safe, resource-and energy-saving agrotechnological measures to control the level of contamination of agricultural land. The research was carried out during 2016-2020 in a stationary two – factor field experiment, which includes 5 alternative tillage systems (plowing, flat – cutting processing, differentiated – chiseling, shallow and surface – disking) and 3 fertilizer systems (without fertilizers; earning in the soil by – products of the predecessor; by-products + mineral fertilizers) in a short-term grain crop rotation (winter wheat-corn for grain-spring barley-soy) on gray large-sawn-light loamy forest soils.It was found that in agrocenoses of corn for grain and soybeans during the growing season, a small-year type of contamination is formed with a predominance of representatives of the Poaceae family, the monocotyledonous class, in particular Echinochloa crus-galli L. and Setaria glauca L.The best results in controlling of the development of segetal vegetation on experimental variants were provided by varieties of deep tillage (plow, flat-cut or chisel) against the background of an organic-mineral fertilizer system with the introduction of by-products of the predecessor into the soil and the introduction of mineral fertilizers. Such fertilizer systems decreased the contamination of crops by 38.9%.When cultivating the soil without turning the soil chunk – flat-cut and disking, against the background without fertilizers, the development of segetal vegetation was poorly controlled.Systems of minimized–shallow and surface disk treatments significantly (up to 88%) increased the abundance and (up to 91%) weight indicators of crop weed contamination in the pre-harvest period compared to multi-depth plowing and differentiated system of basic soil tilling.
