In a long-term places, located on the experimental fields of Siberian Research Institute of Agriculture (Omsk), the schemes of field crop rotations were modernized by introducing oil crops (rapeseed, soybean) into rotation and replacing the repeated wheat crops with barley and oats. Accounting of grain crops productivity and accompanying observations were carried out in three field rotations of different lengths of rotation (four- and five-field) and on permanent sowing. The repetition of the experiments is fourfold. The system of agrotechnical measures recommended for the zone of the forest-steppe of Western Siberia was applied. The study of predecessors in the cultivation of crops for various purposes was carried out in field experiments using conventional methods. The humus content for rotation in the soil layer of 0-40 cm increased by 0.19% in the crop rotation “rapeseed - wheat spring wheat - barley - soybean - spring wheat”. The largest accumulation of humus (0.83%) was in the rotation “soybean - spring wheat - barley – oats”. During the years of research wheat productivity varied from 0.82 to 2.22 tons per hectare. Wheat was the first crop in all its predecessors to form grains, on average, by 0.3-0.5 tons per hectare, than the second crop. The yield of soybeans in the crop rotation was 1.23-1.78 tons per hectare. The productivity of rapeseed was low, its productivity over the years was 1.31 tons per hectare. Grain-fodder crops (barley, oats) averaged 0.4-0.6 tons per hectare, higher than the spring wheat productivity in the alternating rotation. The maximum yield of grain from a hectare of arable land was noted in the crop-steam rotation and amounted to 1.7 tons. An increase in the yield of feed-protein units was observed in crop rotations saturated with oil crops (rapeseed and soybean) and amounted to 3.4-4.0 tons per hectare. The economic calculation showed that the cultivation of field crops in the rotational crop rotation of “soybean - wheat - barley – oats” increased profitability by 44%, net income - by half, in comparison with the control variant. The obtained materials can be used to develop schemes of field crop rotations for the zone of the forest-steppe of Western Siberia.

The study was conducted in the subzone of unstable humidification of the Forest-Steppe on chernozem typical low-humus Panfil research station NSC «Institute of Agriculture NAAS».The study was conducted in the subzone of unstable humidification of the Forest-Steppe on chernozem typical low-humus Panfil research station NSC «Institute of Agriculture NAAS».The aim of the research is to establish the influence of the structure, set and placement of field crops in a 4-field crop rotation for 100 % grain saturation on the overall productivity, yield and quality of corn grain in particular.The technology of growing crops in the experiment is generally accepted and recommended for the research area.Varieties and hybrids of agricultural crops entered into the State Register were sown in the experiment. Chemical plant protection products were used for the production of competitive commodity products of cereals.The results of studies conducted in a long-term stationary field experiment, established in 2001, to study crop rotations on typical chernozems of unstable moisture of the Left Bank Forest-Steppe, convincingly show that for highly specialized farms the most rational in this area are 4-field crop rotations. saturation with grain crops (winter wheat peas-corn for spring barley grain) using various fertilizer systems (without fertilizers), mineral (with the introduction of N60P60K60), organo-mineral (NPK + by-products of the predecessor), organic fertilizer systems (by-products of the predecessor)). The grain yield of corn depended on the fertilizer system and was in the range of 5.86–8.30 t/ha. Productivity of crop rotation area for harvesting from 1 ha of arable land with corn for grain in 4-field crop rotation was: grain – 4.54–6.29 tons, fodder units –7.48–10.47 tons; digestible protein – 0.60–0.84 tons. The economic efficiency of growing corn for grain in short-rotation crop rotation, depending on the fertilizer system, is: relatively net profit – 16.04–21.34 thousand UAH/ha, the level of profitability –112 –180 %.

The results of long-term research in experiments with crop rotations with different clover saturation are presented. It is shown that the cluster has a positive effect on the main indicators of vegetation of dark-gray forest soil. The introduction of two fields of perennial grasses into the six-field crop rotation significantly increases both the humus reserves and increases the productivity of arable land by 1.5–2 times compared to the crop rotation with a field of pure steam.

The long-term research conducted in 2002-2017 in a long stationary experiment on studying different types of field crop rotations under conditions of the Kirov region showed that on sod-podzolic soils the loss of humus could be lowered using agro technical methods. The most critical of them include the reduction of a portion of bare fallow, transition to sown and green-manure fallow, expanded use of perennial legume and grain-legume crops and intercrop sowings. In eight-field crop rotations when using such means of a biologization as plowing of the root-stubble residues, aboveground mass of green-manure crops in fallow fields and intercrop sowings, the supply of organic substance was within 17.24-83.03 t/ha. By mineral-ization of this substance 7.64-11.51 t of humus were produced. In a crop rotation with bare fallow there is a negative balance of humus of -0.06 t/ha. The positive balance is obtained when using sown, green-manure fallows, intercrop sowings (two-three fields), and introduction of up to 25% perennial legumes to the structure of crop rotations. The formation of 0.96-1.44 t/ha of humus in the arable layer provides positive balance of 0.20-0.72 t/ha. The increase of the part of grain crops up to 62.5-75.0% in the structure of crop rotations resulted in rise of their efficiency up to 4.74-4.79 thousand fodder units. It was 0.27-0.32 thousand fodder units higher than in the control crop rotation with bare fallow. Dependence of productivity of agricultural crops on humus content was insignificantly negative (r = -0.16). The efficiency of the studied crop rotations depended considerably on the amount of productive moisture in the soil in a phase of ear formation of grain crops (r = -0.78) and on biological activity of the soil (r = -0.80).
