Background. Fungal diseases are the main cause of the deterioration of grain quality and lower yield of cereals crops. Reduction of acreage, and, as a consequence, violation of crop rotation rules, oversaturation of fields with cereals, spring and summer droughts contribute to the mass emergence and widespreading of new obligate and facultative diseases in all regions of the country. Therefore, the search for a variety of donors and sources of sustainability is a vital task.Materials and methods. Materials engaged in the research were kernels of 41 oat accessions from the VIR collection of plant genetic resources, obtained in 2016–2018 in field crop rotations by the Genetic Diversity Research Department of ARHIBAN (Mikhnevo, Stupino District, Moscow Province). The specific diversity of micromycetes in grain was identified using Litvinov’s “wet chambers” technique and light microscopy.Results. The dominant pathocomplex of micromycetes in oat grain in Moscow Province was found to belong to the genera Alternaria (A. infectoria, A. tennuissima), Cladosporium (Cl. cladosporioides, Cl. herbarum) and Fusarium (F. avenaceum, F. culmorum, F. heterosporum, F. nivale var. nivale, F. oxysporum, F. poae, F. proliferatum, F. solani, F. sporotrichioides var. minus, and F. tricintum).Conclusion. The hulled cultivars ‘Bulanyi’ (VIR-15277, Russia, Moscow Prov.) and ‘Zakat’ (VIR-15384, Ukraine), and the naked cultivar Mestnyi (VIR-15290, UK) demonstrated the least contamination with pathogens: Fusarium fungi in these accessions were represented by one species – F. avenaceum.

Positive Effect

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.

Oil Crops

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 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).

Purpose. To establish the influence of the soybean crops protection from diseases system on reduction the degree of damage and grain yield increase in conditions of the Right-Bank Forest-Steppe zone. Methods. Field, quantitative-weight, comparative-calculation, mathematical-statistical. Results. Dependence of the effectiveness of soybean protection systems against diseases (fusarium wilt, septoria, bacteriosis) and crop rotation is revealed. Application of the system of soybean protection against diseases grown in a 4-field crop rotation reduced the incidence of plant diseases by more than 2 times compared to the control, which significantly affected the level of soybean yield. In the areas of application of the soybean protection system against the most common diseases, which consists in pre-sowing seed treatment (Rhizoactive 2.0 kg/t + Maxim XL 035FS (1.0 l/t) in combination with spraying crops with Abacus fungicide (1.5 l/ha), provided an increase in seed yield from 1.89 to 2.16 t/ha (14.3%) and from 2.32 to 2.64 t/ha (13.8%) respectively depending on 2- and 4-field soybean-corn crop rotations cultivation. Even higher yields of soybean seeds were obtained from the effects of this protection system together with twice done fertilization of soybeans with Plantafol (2.0 kg/ha). As a result, the yield of soybean seeds increased on average over 5 years by 0.27-0.65 t/ha, or 13-28%, compared with the control, where soybeans were grown without fertilization, and only pre-sowing treatment of seeds with the introduction of fungicide was carried out. Conclusions. It was found that pre-sowing seed treatment (Rhizoactive + Maxim ХL 035 FS) in combination with Abacus fungicide and Plantafol fertilization helped to increase soybean seed yield from 1.89 t/ha on the control (without seed treatment in 2-field crop rotation) to 2.76 and 2.97 t/ha when using these drugs in three-field and four-field soybean-corn crop rotations or, respectively, by 46 and 57% more.

The analysis of the influence of species and the fullness of crop rotations on the productivity and efficiency of grain crops is given. It was revealed that the highest grain yield is observed in a 4-field grain-fallow crop rotation. The absence of a field of late spring crops (millet) in 2- and 3-field crop rotations reduces grain yield in comparison with 4- and 7-field crops, both on average over 28 years (1991-2018), and in wet and middle years. The bioenergy coefficient, judging by the costs and grain yield, was highest in a 2-field grain-fallow crop rotation (4.94), then in a 4-field rotation (4.60), then in decreasing order: 7-field (3.86) and 3- field (3.73). In calculating the costs of labor, fuel and energy per 1 ton of grain from arable land, the lowest indicators were obtained in 2-field and 4-field crop rotations. It has been established that in terms of production costs per hectare of arable land, the cost of production of 1 ton of grain, conditionally net income per hectare of arable land, the level of profitability, the leading place is occupied by a 2-field grain-fallow crop rotation. For example, the lowest production costs were noted in a 2-field grain-fallow crop rotation (7782.00 rubles), the highest - in a 7-field (13835.56 rubles). Hence, the lowest production cost of 1 ton of grain was obtained in a 2-field crop rotation, amounting to 5598.56 rubles, followed by a 4-field crop rotation with millet - 7392.66 rubles. And according to the level of profitability, as mentioned above, grain-fallow crop rotations are arranged in decreasing order with the advantage of a 2-field crop rotation in the following order: two-, four-, three- and seven-field - respectively 116.1; 53.2; 48.2 and 37.0 %.

The aim of the research is to take a comparative assessment of the amount of plowed down plant residues in various field crop rotations in the conditions of the Republic of Mari El. The study was carried out in 2013-2018 on a stationary site in a two-factor experiment. Factor A ‒ types of crop rotations and shift of crops: 1. Grain and grass crop rotation (oats + clover, clover of the 1st year of use (y.u.) for green mass, winter rye, vetch and oat mixture for grain, spring wheat, barley. 2. I fruit-changing crop rotation (vetch and oat mix for green fodder, winter rye, barley, potato, vetch and oat mixture for grain, spring wheat). 3. II fruit-changing crop rotation (vetch and oat mixture for grain, spring wheat, potato with manure (80 t/ha), barley + clover, clover of the 1st year of use for green mass, winter rye). 4. III fruit-changing crop rotation (barley + clover, clover of the 1st year of use for green mass, clover of the 2nd year of use for green mass, winter rye, potato, oats). Factor B ‒ mineral fertilizers: 1. Without fertilizers. 2. N60P60K60. In the control grain and grass crop rotation with a oneyear use of clover, 3.02±0.06 t/ha of crop-root residues were received per year on the average. In the I fruit-changing crop rotation, due to the replacement of clover with potato, residues formed 2.14±0.04 t/ha, which was significantly less than the control variant (LSD05 in factor А ‒ 0.21). In the II fruit-changing crop rotation, the accumulation of crop-root residues amounted to 2.91±0.07 t/ha. Compared to the control, it was within the limits of experimental error. The largest number of crop-root residues was accumulated in the III fruit-changing crop rotation (3.37±0.07 t/ha). The use of mineral fertilizers significantly increased the bulk of crop-root residues in all crop rotations by 0.16 t/ha per year on the average (LSD05 in factor B ‒ 0.15). Carbon to nitrogen ratio (C:N) in the crop-root residues of clover and potato was 18…20, in the vetch-oat mixture it was 25…31, in spring grain crops it was 39…41, and in winter rye it was 53.

The influence of rotation length and fullness of grain – fallow crop rotations with a different set of biological groups (biogroupps) - winter, early spring and late spring crops on the yield of grain crops and grain yield from 1 hectare (ha) of arable land in the chernozem steppe of the Saratov Right Bank is analyzed, based on calculations for 4-field - 8 rotations, starting from 1989 and ending in 2020 (2-field - 16 rotations, 3-field - 10). It was revealed that the highest grain yield of 1.63 tons (t) from 1 ha of arable land, both on average for 32 years (1989-2020), and (1.82 t / ha) in the first-fourth (1989-2004) and (1.44 t/ha) of the fifth-eighth rotations (2005-2020), is observed in the 4-field grain – fallow crop rotation with a set of biogroupps-winter, spring early and late. The absence of a field of spring late crop (millet) in the 2 - and 3-field crop rotations reduces the grain yield by 0.11 and 0.30 t/ha, respectively, in comparison with the 4-field, both on average for all years, and by 0.22 and 0.28 t/ha in the first-fourth and by 0.20 and 0.32 t/ha in the fifth-eighth rotations. During the transition from the first-fourth rotation to the fifth-eighth, a significant decrease in the yield of field crops was established: winter wheat in the 3-field crop rotation by 0.87 t/ha or 26.6 %, 2-field by 0.72 t/ha or 22.4% and 4-field by 0.70 t/ha or 21.8 %; millet by 0.43 t/ha or 16.3 %, spring hard by 0.40 t/ha or 29.6 %, soft by 0.35 t/ha or 24.6 %. In all three spring crops, the yield reduction is 2.0 times lower than that of winter wheat. In general, according to crop rotations, the yield of winter wheat, both for the entire period of research, and in the first-fourth, fifth-eighth rotation, fluctuated within limited of the error of the experiment.

The research shows, that an increase of phytocoenoses provided an increase of phytomass volume in the biological cycle from 63.5 to 114.3 t/ha. The yield of phytomass in a crop rotation, different in structure and set of crops, was as follows: for four-field and five-field crop rotation - 63.5-86.7 t/ha, six field - 89.4, seven-field - 96.9, and eight-field - 114.3 t/ha. The optimization of the ratio of grain, technical and fodder crops allowed us to regulate quantitative parameters of crops’ phytomass, which was alienated from agrocoenosis. The yield of the main products, alienated from the field was, as follows: in four-field crop rotation -20.7 t/ha, five-field - 26.6, six-field -37.8, seven field -28.4 and eight field - 41.3 t/ha, which was 32.6%, 30.7%, 42.3%, 29.3% and 36.1%,respectively. The rest returned to the soil with by-products and crop remains. The total amount of nutrients (NPK) in the phytomass, involved in the circulation, was within the range for four-field crop rotation (100% of grain crops) – 1.814 kg/ha, five-field (80% grain and 20% technical) – 2.368 kg/hectare, six-field (66.8% of cereals, 33.2% of technical ones) - 2,599 kg/ha, seven-field (57.2% of cereals and 42.8% of technical) - 2.956 kg/ha, eight-field (62.5% of cereals, 25.0 % of technical, 12.5% of fodder) –3.491 kg/ha.
