The research was carried out in order to find new technological and technical solutions that ensure the energy efficiency of agriculture, stabilization and increase in the yield of agricultural crops for the rotation of grain crop rotation in Volga-Vyatka region. The field experiment was started in 2014 in Nizhny Novgorod region. The work was carried out in grain crop rotation: 1. mustard for seeds; 2. winter wheat; 3. soy; 4. spring wheat; 5. peas; 6. oats. The experimental scheme included 5 systems of tillage (factor A), differing in the methods of the main autumn tillage. For each system of soil cultivation, the influence of mineral fertilizers and destructors of plant residues (factor B) was determined. Against the background of natural soil fertility, the most energetically payback option of the main soil cultivation system is autumn plowing with a plow with dumps (energy coefficient 2.93). The use of a plow without plows, a Pottinger Synkro 5030 K chisel cultivator and a Discover XM 44660 nothad disc harrow in a soil cultivation system leads to a decrease in the energy coefficient to 2.84 ... 2.85; and the use of no-till technology - up to 1.88. Against the background of natural soil fertility, the greatest energy return was provided by systems with fall plowing, carried out both with a plow with dumps and without them, as well as with disking as the main soil cultivation in combination with the use of the biological product Stimix®Niva - energy coefficients were in the range of 3 , 03 ... 3.31. When using no-till technology, the highest value of this indicator was noted when N60P60K60 was applied separately (2.27) and together with the biological product Stimix®Niva (2.53). The maximum energy return in the experiment was recorded in the variant with the main tillage of the soil with a Pottinger chisel cultivator against the background of N60P60K60 together with the biological product Stimix®Niva - the average energy coefficient was 3.45

The article reflects the results of research on the study of crop rotation productivity and energy efficiency components of crop rotation technology in terms of depending on different methods and depth of basic tillage. The purpose of the research was to determine the impact of basic tillage and fertilization on crop rotation productivity indicators and indicators of economic efficiency of crop rotation technology in irrigated conditions in the south of Ukraine. Methods: the field, in-gravimetric, visual, laboratory, calculation-comparative, mathematically-statistical and confessedly in Ukraine methods and methodical recommendations. The research was conducted during 2016-2019 in the research fields of the Askanian SARS IIA NAAS of Ukraine. Results. The use of differentiated and shallow single-depth system of basic tillage to the same productivity indicators at the level of 8.21 and 8.22 t.o.o./ha of products. However, the use of shallow tillage with different depths increased the productivity to 8.49 tons of water/ha, or 3.3%, and with no-till the lowest productivity was obtained 7.15 tons of water/ha. At the same time, the organo-mineral system of fertilizer N90P40 + green manure + crop residues yielded at the level of 7.61 tons per hectare. The improvement of nitrogen nutrition of crop rotations to N105P40 + green manure to get her with the earning of crop residues increased this figure to 8.06 ton so.o./ha, or 5.9% more than the control. At the same time, the maximum productivity indicators of 8.52 tons per hectare were obtained for the N120P40 system + green manure + post-harvest residues, which is actually 12% more than in the control. The reduction of total energy consumption was obtained with a shallow single-depth system of main cultivation of 26.45 GJ/ha, and the lowest values of 25.27 GJ/ha were obtained with no-till, which is 6.8% less than in the control. Application of organo-mineral fertilizer system N90P40 + green manure + post harvest residues formed costs at the level of 24.94 GJ/ha, increase of nitrogen nutrition of crop rotations to N105P40 + green manure with post harvest residues increased costs to 26.35 GJ/ha, and the highest costs 26.37 GJ/ha was obtained in the variant N120P40 + green manure, where the figures were higher by 11.5% compared to the control. Almost the same energy yield was obtained for differentiated and single-depth shallow tillage systems 127.33 and 127.64 GJha, respectively. The application of the system of multi-depth tillage increased the yield to 133.24 GJ/ha. Conclusion. The calculation of energy efficiency testifies that growing of agricultural cultures at bringing of N120Р40 + green manure + post-harvest residues in the system of the plowless on different depth is most expedient and justified from the power point of view. Technology of growing, which is based on these agrotechnology measures provides the receipt of maximal energy coefficient at the level of 4,96

The research was carried out in order to find new technological and technical solutions that ensure the economic efficiency of farming, stabilization and increase of crop yields due to the rotation of grain crop rotation in the conditions of the southeast of the Volga-Vyatka region. The field experience was established in 2014 in the Nizhny Novgorod region. Scientific research was carried out in the grain crop rotation: 1. mustard for seeds 2. winter wheat; 3. soy; 4. spring wheat; 5. peas; 6. oats. The scheme of the experiment included 5 tillage systems (factor A), which differ in the methods of the main finch tillage. For each tillage system, the effect of mineral fertilizers at a dose of N60P60K60 and destructors of plant residues (ammonium nitrate at a dose of 10 kg a.i. per 1 ton of straw and the biological product Stimix®Niva) was determined (factor B). All the studied tillage systems and applied mineral fertilizers with straw destructors allow for expanded agricultural production. The lowest conditional profitability of production was found for the traditional tillage system using a plow with dumps - 99.3 %, which is 34.6% lower than the conditional profitability in the field experiment variants using disking as the main autumn tillage - which provides the highest average conditional profitability of 133.9 %. The average conditional profitability of grain production using the No-till technology for the rotation of the grain crop rotation was 123.3 %, which is 24.0 % higher than the conditional profitability of traditional tillage and 10.6 % lower than that of the resource-saving technology of agricultural production using a disc harrow. At the same time, the direct sowing technology provides the highest absolute profitability of grain production for the rotation of a six-field crop rotation in the conditions of the southeast of the Volga-Vyatka region when cultivating crops according to N60P60K60 background together with the use of the biological product Stimix®Niva – 170.9 %

The development of resource-saving tillage and direct seeding technologies (no-till) of field crops end up making a profit when it is based on the results of research and practice but this is not the case in all regions. Taking this into account, in the central zone of the Krasnodar Region in the permanent crop rotation from 2013 through 2018, we studied the integrated effect of plowing (22-24 cm -the control), surface tillage (6-8 cm) and zero tillage (herbicide treatment) and the crop in the rotation on the economic efficiency of production and elements of soil fertility. The average annual air temperature in the area is +12.1°C; the precipitation amount is 614 mm. The soil is represented by ordinary chernozem; humus amount in the arable layer makes 3.8%; P2O5-22-28 mg kg of soil; K2O -350-380 mg kg of soil (according to B.P. Machigin). The accounting area of the plots amounted to 5000 m2; fourfold plot replica-tion; threefold temporal replication. The crops were sown with the Rapid600 seeder with fertilizer application. Pesti-cides and growth promoters were used. The crops were harvested with a Claas Tucano combine harvester. It was found that the tillage variants affected the yields of crown flax, winter wheat,foxtail millet in stubble field, and field pea; and also changed the production costs and the condi-tional net income for crops and the course of the crop rota-tion. Under direct seeding technology, the conditional net income for the course of the crop rotation made 58.6 thou-sand rubles per ha; fuel consumption -127 kg ha and labor costs -16.98 man-hours per ha which was by 5%, 43% and 11%, respectively, less than those in the control. Sur-face tillage also had an advantage in terms of these indica-tors. Moldboard plowing reduced the intensity of organic matter accumulation 1.5-1.2 times as compared to direct seeding (no-till) and surface tillage. The cultivation of 4 crops in a course of the crop rotation for 3 agricultural years stabilizes economic indicators and soil fertility. The developed technologies for crop optimization in a rotation (the crops in constant demand by the market); adaptive methods of basic tillage; preservation of soil fertility may be used by land users with similar soil and climatic conditions.

Field experiments on revealing of effectiveness of traditional and resource-saving technologies at cereal crop cultivation were conducted in 2011-2017 on sod-podzolic middle-clay soils of Kirov region. As ways of basic soil cultivation, the following variants were used: moldboard plowing and combined soil cultivation with aggregate KPA-2.2, which doing simultaneously surface tilling and disking for better stubble processing. On average, two trials experience productivity on traditional technology were as follows: vetch-oat mixture – 6.89 t/ha of dry matter; winter rye – 2.28 t/ha; spring wheat – 2.60 t/ha; pea-oat mix – 8.10 t/ha; barley – 3.40 t/ha; oat – 2.91 t/ha. At use of resource-saving combined soil tilling productivity of winter rye, spring wheat, and oat was in average higher than at plowing and consisted 2.47; 2.67; and 3.31 t/ha correspondingly. Yield of vetch- and pea-oat mix, barley was lower – 6.62, 7.81, and 2.94 t/ha correspondingly. Productivity of crop rotation with plowing was 3.41 thousand fodder units; coefficient of energy efficiency was 2.75; self-cost of 1 ton of basic production was 2771 rubles; level of total profitability – 77.3 %. When plowing was substituted with resource-saving method of basic soil tilling – surface combined cultivation – average productivity of crop rotation was 3.39 thousand fodder units at coefficient of energy efficiency of 2.81, self-cost of basic production – 2673 rubles per ton, and total profitability 80.7%.

Green Manure Crops

The reproduction of natural soil fertility is the most important direction in solving the problem of sustainable development of agriculture and the entire agro-industrial complex. The realization of this direction should be considered together with greening of agriculture. Considering greening of agriculture, the agricultural ecosystem can be divided into the components and each component can be considered separately. The main aspects of greening of agriculture are alternative systems of agriculture, non-pesticide crop cultivation technologies, binary or mixed crops, constructing of crop rotations to supply the plants with the main nutrition elements, application of green manure crops to improve soil fertility, etc. Green manure crops are the plants which are grown to improve soil fertility and they are called ‘green manure’. Green manure crops decompose in the soil much faster than other organic fertilizers thereby supplying plants with nutrition elements better. Plowed green manure improves water, air and food regimes of soil, improves its fertility and grain crop productivity.

The analysis of the main historical stages of the development of the theory of minimization of tillage, as well as data obtained during long-term stationary studies, is made. Over the long-term period, the use of non-dump resource-saving tillage in crop rotation was not inferior in efficiency, and in some indicators even exceeded the combined multi-depth tillage (including dump loosening of the soil). The data on the positive effect of the combination of the no-till system and the cultivation of groundcover crops in the crop rotation on the soil fertility with signs of its extended reproduction are presented.

In OOO “Dubovitskoe” which was organized in 2006 as investment project of the AO “Shchelkovo Agrokhim” for 2010 – 2012 three advanced crop rotations have been developed. Before their introduction the grain crops fraction in the cropping system was 62%, then it fell to 49%. At the same time the portion of raw crops increased from 15 to 20%, legumes from 6 to 8%, others (buckwheat, grain maize, etc.) - up to 23%. As of 2017, the crops of leguminous crops have increased noteworthily. There are two predominant soil types here heavy clay loam podzolized chernozem (6615 ha) and grey forest soil (856 ha). Weighted average indicators (as of 2017): humus content in the soils of arable land is 5, 34%; acidity pH is 4.92; labile phosphorus - 111.8 mg / kg soil; exchange potassium - 144 mg / kg soil. The coefficient of the soil fertility in the enterprise (weighted average) is 0.66. This means that maintaining and increasing the soil fertility for arable land of the enterprise is critical task. As a result of the research, it has been established that the technologies introduced in the crop vegetation management (CVS) in the crop rotation conditions ensure high productivity of cultivated crops and stability of humus content in soils as an energy basis and a guarantor of increasing fertility. The indicators of the labile phosphorus Р205 and exchange potassium К20 in the soils depending on the crop rotation vary from a certain decrease to expressed steady growth. Therefore it is necessary to specify seeding rates based on actual data. Sustainable soil acidification in the crop rotations under crop cultivation in OOO “Dubovitskoe” it is the result of the acid feterlizers high rates application, during studying period did not carried out required agromelioration with calcium contenting elements.

The article presents the results of comparative evaluation of the efficiency of the long-term application of mineral and organic fertilizers in the crop rotation system. It was found that the application of the mineral fertilizer system increased the value of hydrolytic acidity of the soil from 4,30 to 5,29 mg-eq per 100 g of soil, the indicator of metabolic acidity decreased from 5,2 to 4,9 pH units. By the end of the 11th rotation for both fertilizer systems, the content of mobile phosphorus increased by more than 4 times relative to the initial value, its mobility indicator – by 2,2-3,2 times compared with the control. The use of the organo-mineral system was accompanied by an increase in the content of humus by 0,35 % and a decrease in the C:N ratio from 11,2 to 8,9. The increased productivity of wheat was revealed when applying nitrogen and nitrogen-phosphorus fertilizers against the background of prolonged use of the mineral and organo-mineral fertilizer system. The change in wheat productivity by 56 % depended on the content of mineral nitrogen, mobile phosphorus, humus in the topsoil, and on the phosphate ion mobility. Soybean productivity depended on soil fertility indicators only by 24 %: the relationship between soybean productivity and the mineral forms of nitrogen and phosphorus is weak and direct, between productivity and P2O5 mobility - weak and inverse, with humus - moderate and direct.
