THE EFFECT OF PRE-PLANT APPLICATION OF THE MINERAL FERTILIZERS ON THE PRODUCTIVITY OF SOYBEAN VARETIES ON LEACHED CHERNOZEM

In 2020, we studied the effect of pre-plant application of the mineral fertilizers in doses of N30P30 and N30P30S21 on the seed productivity, oil and protein content and their yield in soybean varieties Vita, Slavia, Irbis, Vilana beta on leached chernozem of the central natural and climatic zone of the Krasnodar region. On average, the mineral fertilizers contributed to an increase in the yield of varieties by 0.12–014 t/ha, protein yield – by 39–43 kg/ha, oil yield – by 21–28 kg/ha.
