The highest yield level was obtained for MIP Assol (6.01 t/ha), Estafeta myronivska (5.52 t/ha), MIP Dniprianka (5.77 t/ha) after the precrop soybean when sowing at 5.10 The highest 1000 kernel weight was formed in the varieties Estafeta myronivska (46.2 g) and MIP Dniprianka (46.4 g) when sowing at 5.10 after the precrop soybean, and in the variety MIP Assol (44.7 g) when sowing at 5.10 after the precrop sunflower. A significant influence of nitrogen fertilizer application rates on the yield and sowing qualities of seeds of winter bread wheat varieties MIP Assol, Estafeta myronivska and MIP Dniprianka has been proved. The application of UAN-32 at the rate of 50 kg/ha of active substance and 75 kg/ha of active substance increased the yield by 0.59–0.84 t/ha, the seed yield by 6–11% and the 1000 kernel weight by 1.6–2.4 g compared to the variants with no nitrogen fertilizers. It was found that when the seeds were heated for 5 minutes, in winter wheat varieties sprouting activity increased by 16.0 %, and the indicators of seed vigor and laboratory germination decreased by 11.90 % and 10.5 %, respectively. When the seeds were heated for 10 minutes, the sprouting activity decreased by 25.3%, seed vigor by 46.3% and laboratory germination by 42.2%. From the determining the postharvest ripening period, it was found that the varieties MIP Aelita, MIP Darunok, MIP Vidznaka, MIP Feieriia, MIP Fortuna have a short postharvest ripening period of up to 30 days, and the varieties MIP Nika, MIP Roksolana, MIP Yuvileina have a long pos-harvest ripening period of 40–55 days.
