“…The interest in soy is due to the high-quality composition of its grain, which, depending on the variety and growing conditions, contains 35-55% easily digestible protein, 17-27% fat, up to 30% carbohydrates, vitamins, etc. Due to its rich and diverse chemical composition, it is widely used as a food, fodder and technical crop, while having great agrotechnical importance [1][2][3][4].…”

The article presents the results of research on the reaction of soybean plants depending on the timing of sowing in the foothill zone of the Republic of North Ossetia-Alania. The need to improve the timing of sowing occurs with the introduction of new varieties of various ripeness in the main and intermediate crops. The purpose of the paper is to study the effect of sowing dates on the yield of soybean seeds in the conditions of the foothill zone of the RNO-Alania. The scientific novelty was to establish optimal sowing dates that would ensure optimal plant growth and development and high productivity. Our research was carried out in the experimental fields of the North Caucasian Research Institute of Mountain and Piedmont Agriculture of the VSC RAS in 2018-2021. The object of research was the varieties of breeding of the Federal scientific center "V.S. Pustovoit All-Russian Research Institute of Oil Crops. Two main types of soils prevail in the foothill zone: chernozems of varying degrees of leaching, as well as meadow and meadow-boggy soils. The arable layer contains from 3 to 4.4% humus. Down the profile, the amount of humus decreases gradually. The reaction of the soil solution in the upper horizons is neutral, in horizons deeper than 80-90 cm – slightly alkaline. The predecessor of the experimental plots was corn for grain. It was found that at early sowing dates (April 20 - May 5) resulted in higher field germination (87-93%), plant foliage of 46.9 thousand m2/ha and their survival rate for harvesting 84-91%. More nodules formed on the roots of the plants. The maximum yield is 2.6 t/ha, obtained during sowing on April 30.

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.

The article provides the data of the field experiment (2016-2019) on studying soybean varieties in order to determine their suitability for cultivation in Kaluga region (the central part of the Non-Chernozem region of the Russian Federation) and their use as a source of agronomic traits for further breeding work. The objects for the research were the soybean varieties of Russian (Mageva, Svetlaya, Kasatka, Maleta, Okskaya, Georgia) and Belarusian (Pripyat and Volma) breeding. Cultivation of soybean varieties in the northern regions of the country is limited due to the short growing season. During the research, the source of early ripening trait has been identified – Kasatka variety had the shortest vegetation period (109 days, 10 days less than Mageva standard variety). According to the plant height Pripyat (93.5 cm) and Okskaya (92.7 cm) varieties have been noted. In comparison to the control, Maleta, Pripyat and Volma varieties showed a steady dynamics towards dry matter accumulation increase. Plant yield index is the most important indicator in assessing soybean varieties genotype suitability for the certain cultivation area. A close correlation has been established between Svetlaya and Okskaya varieties yield indices and moisture availability indicators during the growing season (the amount of precipitation and the hydrothermal coefficient) (r = 0.9). The yield of the Belarusian Volma and Pripyat varieties showed a strong correlation between the average density and precipitation (r = 0.5-0.7) and HTC (r = 0.4-0.6), which proved the possibility of their cultivation in the Non-Chernozem region. On average over the research Pripyat variety has been the most productive one (2.0 t/ha, 21 % higher than the standard), which makes it useful as a source for increased productivity trait in soybean breeding.
