The Impact of Sowing Timing and Nutrition on Soybean Yields on the Absheron Peninsula in the Context of Climate Change

Abstract. The climate changes that have occurred over the past decades, as well as other plants, affect the yield of soybean grains. The study mainly examines the change in qualitative and quantitative indicators of soybean yield and development depending on the timing of sowing and the use of various fertilizer options. It was found that sowing in the third decade of April contributed to the production of mass seedlings, and at the stage of plant development, with a 60 x 10 cm sowing scheme, the results were different from the rest. On the irrigated gray-brown soils where the experiments were conducted, optimal conditions for seed swelling were created against the background of the use of N60P40+15 tons manure in cultivation, which, compared with the option without fertilizers, promotes the appearance of mass shoots and formation 3-4 days later than the ripening phase. According to the results of the study, it was noted that high yields of soybean grains are achieved against the background of the application of an optimal sowing scheme using manure N60P40+15 tons. The yield in this variant was 32.0 c/ha higher. This option should be considered significant in all directions.
