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 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.

The influence of the main tillage and plant protection on the yield and its structure of grain legumes has been studied. Combined tillage with adaptively integrated plant protection increased the studied parameters by 5,4-8,7% compared to the minimum tillage and the first level of plant protection. The maximum yield was obtained on peas by the combined tillage in crop rotations of 2,65 t / ha, and with the minimum tillage – 2,36 t / ha. The effect of combined tillage on soybeans was also higher than on the minimum, where the yield was 2,25 t / ha and 1.94 t / ha, respectively. The yield of chickpea is also higher for combined processing – 2,27 t / ha, and at the minimum –1.94 t / ha. The yield of lupine for soil cultivation is 2,23 t / ha and – 2,00 t / ha.

Ecological Role

The article presents the results of a theoretical review of the role of the structure of cultivated areas and crop rotations in agriculture. Based on experimental studies, recommendations are given for optimizing the structure of cultivated areas and the system of crop rotations in the forest-steppe zone of the Volga region. The structure of sown areas and crop rotations should expand the species composition of cultivated crops, introduce intermediate crops. Our research shows that the structure of sown areas should reduce the proportion of pure fallow to 40% of the area with winter grain crops to increase the productivity of arable land, protect the soil from erosion, preserve and reproduce its fertility. At the same time, it is necessary to increase the area of perennial leguminous grasses and legume-cereal mixtures and bring their share to 25% of the cultivated area. This requires introducing grain-grass and fruit crop rotations, which will improve the ecological state of the soil and crops, and ensure the reproduction of soil fertility.
