Today, in the scientific and practical field, as well as a long time later, much attention is paid to improving the quality and quantity of yield. To obtain the desired results, we considered various systems of basic soil tillage in the growing of winter wheat, namely, determined the influence of basic soil tillage systems on the autumn development of winter wheat in the Luhansk region. The results of research of the influence of the basic soil tillage and the forecrop on the density and content of productive moisture in the soil layer of ordinary chernozems and on the autumn phases of development of winter wheat variety "Antara" are discussed. The research was performed in 2018-2020 in the fields of the department of scientific and technical training in agronomy and farms located in the north-central moderately arid subzone of Luhansk region. Three methods of soil tillage have been studied by us: moldboard ploughing -depth 22 cm; moldboard-less disking ploughing -depth 10 cm; moldboard-free subsurface cultivation -depth 12 cm. Forecrops: occupied fallow, sunflower, maize. The research was performed according to generally accepted methods. By means of research was established the advantage of moldboard ploughing over moldboardless ploughing. Moldboard soil ploughing contributed to the creation of lower density in the arable horizon under different forecrops, greater microbiological activity of the soil, better water supply during the autumn vegetative season. Moldboard ploughing increased access to nutrients such as potassium and nitrogen, and moldboardless ploughing accumulated available phosphorus. Improving the agrophysical properties of the soil contributed to the formation of better biometric indices in the autumn vegetative season. The height of the plants where the soil was plowed to the depth 22 cm was higher compared to the height of the plants with moldboard-less disking ploughing to the depth 10 cm. This affected the number of stems, which also increased, the number of leaves and roots increased, respectively. The depth of the tillering node increased relative to the increase in the depth of soil tillage, the weight of 100 absolutely dry plants increased, respectively, almost three to four times. Thus, the basic soil tillage improves the agrophysical properties, increases the microbiological activity of the soil and improves the biometric indices of plants.

The analysis of variability of winter soft wheat lines by quantitative traits is presented. The research was conducted in 2020–2023 in the Rostov region. Seven lines of winter soft wheat of the competitive variety trial were taken as an object of research. The Ermak variety was used as a standard. The yields of the lines during the years of study averaged from 9.78 to 10.12 t/ha with an average of 9.76 t/ha in the experiment. Plant height ranged from 85.0 to 115.0 cm. All the lines studied were classified as small- to medium-grained (32.9–45.9 g) in terms of 1000 grain weight. On average for the years of study, the minimum mass of 1000 grains was formed by the line 1638/19 (34.6 g), and the maximum – by the line 1361/19 (43.5 g). The lines had different groups of ripeness according to the indicator of the earing date. The spikelet length varied from 7.3 to 10.0 cm. The highest spikelet length was formed by the line 1361/19 (10.0 cm), the shortest – by the line 1120/19 (7.3 cm). The number of productive stems ranged from 471 to 924 stems/m2. The maximum number of productive stems for the years of the study was formed by the line 1921/20 (758 pcs./m2), the minimum – by the line 1361/19 (689 pcs./m2). The number of grains per plant ranged from 61.6 to 110.6. On average, the highest number of grains per plant was formed by the line 1638/19 (100.6 pcs.), the lowest – 1343/19 (70.4 pcs.). The grain weight per plant averaged 3.54 g and ranged from 2.26 to 4.56 g. The number of grains per ear varied from 28.9 to 51.5 pieces, the maximum number was formed by the lines 1361/19 (42.7 pcs.) and 1638/19 (41.2 pcs.). In terms of the grain weight per ear the standard was exceeded by the line 1361/19 (1.93 g), the values for the indicator varied from 1.02 to 2.28 g.

Sorghum is one of the main food and feed crops in the world. Rapid population growth in Africa requires a growing amount of local foods such as sorghum. Therefore, breeding work aimed at developing highly productive sorghum varieties and hybrids adapted to the soil and climatic conditions of Africa and the arid conditions of southern Russia is of great urgency. Therefore, it was necessary to identify the adapted samples with valuable economically valuable traits. The current study has been carried out on the experimental plots of the laboratory for grain sorghum breeding and seed production of the FSBSI “Agricultural Research Center “Donskoy”. As objects of the study there have been used the grain sorghum varieties of the National Research Institute of Semi-Arid Resources (NaSARRI) of the Republic of Uganda ‘Seso 1’, ‘Seso 3’, ‘Narosorg 1’, ‘Narosorg 2’, ‘Narosorg 3’, ‘Narosorg 4’, ‘Epuripur’, as well as the variety ‘Zernogradskoe 88’ sown as the standard variety. The study was conducted in accordance with the Methodology of State Variety Testing of Agricultural Crops and B. A. Dospekhov’s Methodology of a field trial. The purpose of the current study was a comprehensive estimation of grain sorghum varieties developed in the research institutions in Uganda under the conditions of the Rostov region to use the selected samples in further breeding work as sources of economically valuable traits. In the conditions of the Rostov region the Ugandan varieties belonged to the group of middle ripening and late ripening varieties. The plant height in the studied varieties varied from 155 to 210 cm. According to the trait “number of grains per panicle” the varieties had a large number of grains (1829–2530 pcs.). The main share of the NaSARRI varieties had a high percentage of raw protein in grain (13.6–14.9%). A low tannin content was established in the varieties ‘Seso 1’ (0.54%), ‘Epuripur’ (0.66%) and ‘Narosorg 1’ (0.71%).
