During 2016-2018, the share of weather conditions on the yield of corn grain reached 69%, and among the investigated factors: hybrids - 31-50%, seedlings and fertilizers - respectively, 7-13 and 6-23%. The application of N90R45K45 increased the grain yield of corn by 0.93 t / ha (14.4%), and N60R30K30 - by 0.68 t / ha (10.6%), compared to the background without fertilizers. The highest grain yield among the studied hybrids formed the mid-life hybrid DK Burshtyn for sowing at tg = 16-18 ?С: against the background of N60R30K30 and N90R45K45 - respectively 8.34 and 8.58 t / ha (conditionally net profit - 19235 and 18229 UAH / ha for profitability 107,6 and 93,1%), and without fertilizers - 7,74 t / ha (for conditionally net profit 20,289 UAH / ha and profitability 143,1%). The highest conditionally net profit was 20311 UAH / ha and profitability of 157.8% provided medium-term hybrid DC Burshtyn for sowing at Tg = 12-14 ° C on the background without fertilizers.
