The paper presents the results of studies of grain crops row sowing method agrotechnical indicators after the modernization of the working bodies of the SZS-2.1 seeder-cultivator. The SZS-2,1 stubble cultivator seeder has found wide application in the arid regions of the Republic of Buryatia, whose soils are prone to wind erosion. This seeder provides a combination of pre-sowing cultivation, sowing grain crops, applying mineral fertilizers to the sown rows and rolling them on stubble backgrounds, that is, in fields that have been processed since autumn with flat-cutting tools or have not been cultivated at all. Sowing with these seeders with 23 cm row spacing in a row method is the main method of sowing spring wheat in the soil conservation agriculture system. Routine sowing on soils of light texture, subject to wind erosion, causes thickening of plants in a row, which leads to irrational use of the feeding area by plants, increased weediness of crops between rows and, ultimately, to a decrease in yield. A distributor for the coulter has been developed, where the seeds are fed to the distributor. Then, reflecting from the distributor, the seeds are evenly dispersed in the opener under the plow space. Also, instead of serial wedge-shaped packer rollers, ring-spur rollers of the 3KSH-6 type are installed on the seeder. In addition, continuous rolling provides the necessary contact of seeds with the soil, preserves soil moisture and helps to attract it from the lower layers. Thus, the modernization of the SZS-2.1 seeder made it possible to substantiate subsurface-spread strip sowing with continuous rolling, which ultimately led to an increase in grain yield by 10-15%.

Field experiments were carried out in the Rostov region on the slope of ordinary chernozems in the system of contour-strip organization of the territory in 2011-2020. The aim of the research was the development of agrotechnical methods (design of crop rotation, the method of basic tillage and the background of fertilizers), which ensure high productivity of crop rotations on the eroded slope of ordinary chernozems and the preservation of fertility. The experiment included three factors: the design of the crop rotation, the method of the main tillage, the background of mineral fertilizers. It was found that, on average, for the period of research, the level of mineral nutrition has the greatest influence on the productivity of the crop rotation (83.9%), followed by the design of the crop rotation (14.9%). The influence of basic tillage is estimated at only 1.2%. It was found that the introduction of 20% of perennial grasses into the structure of crop rotation reduces soil washout by 19.5-27.7%, and an increase in the proportion of perennial grasses to 40% by 38.3-43.8%. The use of chisel tillage reduces washout by 15.6-24.2%, and with it the loss of humus. In the “C” crop rotation in all variants of the experiment, the humus content increased by 0.010.03%. It was revealed that the productivity of all the studied crop rotations changed under the influence of agrotechnical methods, reaching in the crop rotation “C” with 40% of perennial grasses and 60% of grain crops on average for the studied period the highest value of 3.53 t / ha of grain units, which is 9.3% higher than in the “B” crop rotation and 17.3% higher than in the “A” crop rotation.

The influence of various levels of mineral nutrition on the accumulation of plant-root residues of spring wheat and oats in the conditions of the forest-steppe zone of Western Siberia is studied. The natural agricultural background of leached chernozem was taken as a control. The research was carried out at the station of the Department of Soil Science and Agrochemistry of the State Agrarian University of the Northern Trans-Urals. In the experiment, various doses of mineral fertilizers were used, ensuring the yield of grain crops from 3.0 to 6.0 t/ha. It was found that the mass of plant-root residues of spring wheat and oats has no significant differences and depends on the level of mineral nutrition. On the natural agricultural background, the mass of plant-root residues is 3.24-3.88 t/ha. Fertilization increases the yield of grain crops to 6.0 t/ha, and also increases the amount of plant-root residues: spring wheat - 4.47; oats – 6.04 t/ha. Increasing the doses of mineral fertilizers reduces the ratio of yield to the mass of plant-root residues from 1:1.6 to 1:1.10 units. It was found that almost half of the root system of spring wheat and oats is located in a layer of 0-10 cm, while the share of roots in a layer of 30-40 cm accounts for no more than 16% of the mass.

Row crops represent the most important crops in terms of global cultivated area. Such crops include soybean, corn, wheat, rice, rapeseed, sunflower, and cotton. Row crops agriculture is generally an intensive system of farming used to obtain high yields by employing elevated quantities of organic and mineral fertilizers. Considering this, and the decrease in area of arable land, it becomes crucial to ensure high yield and quality using alternative strategies, such as the use of plant biostimulants. These compounds are increasingly recognized as sustainable solution to optimize nutrient uptake, crop yield, quality, and tolerance to abiotic stresses. In this work, by means of high-throughput plant phenotyping, we evaluated the effectiveness of a set of three new foliar biostimulant prototypes (coded as 52096, 52097, 52113) applied on corn and soybean at application rates 2.5 and 5 mL/L (corresponding to 1 and 2 L/ha respectively). This allowed us to select the most effective prototype (52097, commercial name “YieldOn®”) in increasing digital biovolume (DB) and greener area (GGA) either in soybean (both application rates) or corn (rate 5 mL/L) and decreasing Stress Index (SI) in soybean (both application rates). Molecular mechanism of action of selected prototype 52097 was subsequently characterized through Next Generation Sequencing (NGS). In corn, genes involved in hormone (cytokinin and auxin) metabolism/catabolism, maltose biosynthesis, sugar transport and phloem loading were upregulated after application of prototype 52097. In soybean, genes involved in nitrogen metabolism, metal ion transport (mainly zinc and iron), sulfate reduction, and amino acid biosynthesis were induced. The proposed approach supports the integration of multiple omics to open new perspectives in the discovery, evaluation, and development of innovative and sustainable solutions to meet the increasing needs of row-crops agriculture.

This study discusses a plant breeding and seed system recovery. According to the 2013 information, over 3000 seeders with colters of strip cropping were upgraded, which worked in 64 regions of the country. Simultaneously with the work on the modernization of the seeders for strip cropping, Russian Institute of Mechanization together with LLC “Tekhtsentr Laishevo” and “KhaRaSha” developed a design specification on the universal seeder SUZT 4of strip cropping with 4 meter width and a design specification on unified with it breeding and farming seeder SFS -2 with 2 meter wide. The pilot seeder SUZT-4 was designrd in LLC “KhaRaSha” and in 2012 it was successfully held acceptance tests with the recommendation on production at the Kirov Machine Testing Station. This seeder is designed for strip sowing of cereals, legumes, small-seeded crops and grass with simultaneous application of mineral fertilizers, as well as for early spring narrowband sowing of sparse winter crops and perennial grasses and subsurface mineral fertilizers plant nutrition. In 2013 there have manufactured a pilotmachine of breeding and farming seeder SFS-2 and it was transferred to Machine Testing Station for carrying out acceptance tests. The speeding up the implementing these seeders allow to carry out technological operation of planting crops in a highly effective stripping way with a significant increase of productivity and with high quality seeds. On spring wheat crops, where the seeds were prepared by car SMVO and sowing performed by seeders with ODA colters of strip cropping, the field germination ranged was from 92.5 to 95.6%, which is 4.5-8.1% higher, than seeds, obtained without isolation of their specific weight and drill sowing by double disc coulters. As a result, the higher harvest is formed by 8-10 centner per hectare and more. Additional 1.0 million tons of crops were reaped from improved seeds quality. Thus, the use of universal seeders with single disc - hoe colters and seed-crop cleaning machines SMVO is the most affordable way to increase the crops yield and seed quality for all farms. Key words: selection and seed-farming, Seed-growers association, seed-crop cleaning machine, processing of grain and seed, a seeder with disc-hoe colters, strip cropping .

Monolayers are highly desirable for their evaporation reducing capabilities due to their relatively minimal cost and ease of application. Despite these positive attributes, monolayers have consistently failed to perform effectively due to the harsh wind and wave conditions prevalent across real-world water reserves. An exhaustive and consistent study testing the influence of wind and wave combinations on monolayer performance has yet to be presented in the literature. To remedy this, the effect of simultaneous wind and wave conditions on a benchmark high-performance monolayer (octadecanol suspension, CH3(CH2)16CH2OH) has been analysed. Subjected only to waves, the monolayer remained intact due to its innate ability to compress and expand. However, the constant simultaneous application of wind and waves caused the monolayer to break up and gather down-wind where it volatilised over time. At wind speeds above 1.3 m s−1 the monolayer was completely ineffective. For wind speeds below this threshold, the monolayer had an influence on the evaporation rate dependent on wind speed. From these results a series of application protocols can now be developed for the optimised deployment of monolayers in real-world water reserves. This will be of interest to private, commercial and government organisations involved in the storage and management of water resources.

Investigations on light gray forest soils of the Chuvash Republic were carried out to study the effectiveness of the use of horn-ungulated meal or keratin as a nitrogenous organic fertilizer and zeolite-containing trefoil as a sorbent-type soil improver. The use of horn-ungulted meal as a nitrogen fertilizer of organic origin helps to enhance the biological activity of the soil. Observations during the vegetation period revealed a more intense coloration of the leaf surface, as well as an increase in the area of the assimilative surface of fodder beet and potatoes. The results of the determination of quality indicators has revealed the possibility of obtaining environmentally friendly products, as there has been a decrease in the content of nitrates in root crops fodder beet and potato tubers, increased dry matter content and sugar content in root crops fodder beet and in the tubers of potato dry matter and starch.The conducted studies have revealed the possibility of replacing the mineral form of nitrogen fertilizer with a nitrogen fertilizer of organic origin - horn-ungulated meal (keratin), which is a waste of the livestock industry. The joint application of zeolite-containing fossil meal together with horn-ungulated meal and phosphoric-potassium mineral fertilizers positively affected the increase in the use of nutrients from them not only in the row crops in the year of application, but also in the subsequent barley culture, increasing its yield and economic efficiency.
