Rasulova, V.A.
Soybean as a high-protein and oilseed crop is an important source of food and feed resources, and its production is a highly competitive and profitable industry. Therefore, the development of varietal technology of soybean cultivation, aimed at obtaining high yields and improving grain quality by optimizing plant nutrition, is an urgent task. The article presents the results of three-year research (2020-2022) to study the effect of complex mineral fertilizer NPK in rates of 30, 60 and 90 kg/ha, as well as foliar feeding with complex microfertilizer “Sunny Mix legume vegetation” on yield and quality of soybean seeds of different varieties and lines. As a result of the research, different varietal responsiveness to the applied elements of cultivation technology was established. Thus, in the variety Osmon maximum productivity provided background mineral nutrition N90P90K90 in combination with foliar feeding - yield was 31.8 kg/ha, protein content - 40.7%. Application of mineral fertilizer rate of 60 kg. of active substance per hectare in combination with leaf fertilization on varieties Lancetnaya and Zusha provides an increase in yield up to 27.8 and 30.0 kg/ha compared to the lowest rate (30 kg. of active ingredient per hectare), and simultaneously increases the protein content of seeds up to 41.9% and 42.6%, respectively. At the same time, the highest seed and protein productivity of line L-85 was obtained on the background of N90P90K90 without foliar treatment. Yield was - 29.4 c/ha, protein content - 42.3%
