To determine the peculiarities of the growth and development of corn plants during the growing season and their reaction to the tillage system, fertilizers, sowing dates and other factors in the conditions of the left-bank forest-steppe

According to the results of the research, the grain yield of the early-ripening hybrid DN Nur in the reporting year was maximum in the second sowing period of 4.83 t/ha, of the medium-early DN Astra in the second and third sowing periods of 5.89 and 5.91 t/ha, and of the medium-ripening hybrid DN Drag in the first sowing period of 5.75 t/ha.The use of fertilizers contributed to an increase in the yield of corn hybrids. The highest yield of the hybrids DN Nur, DN Astra and DN Drag was obtained when mineral fertilizers were applied at a dose of N60P60K60.(foliar feeding of plants with liquid concentrated nitrogen fertilizer in the 5-6 leaf phase) against the background of shelf soil cultivation and amounted to 5.39 t/ha, 5.73 and 5.76 t/ha, respectivelyEarly-ripening hybrids provided a yield of 5.48 t/ha with grain moisture of 12.4%, medium-early hybrids - 5.40 t/ha with grain moisture of 13.6%, and medium-ripening hybrids - 5.10 t/ha with grain moisture of 15.6%.The use of fertilizers contributed to an increase in the mass of 1000 grains of corn in 2024 on the hybrid DN Nur from 4.4 to 11.7% (control 215.2 g), DN Astra from 6.2 to 7.7% (control 258.0 g), DN Drag from 8.4 to 16.1% (control 239.6 g).Щодо впливу систем основного обробітку на даний показник, то він був вищим порівняно з поверхневим за полицевого обробітку у гібрида ДН Нур на 7,4 %, за чизельного на 1,9 %; ДН Астра відповідно на 10,4 і 2,5 % і ДН Драг на 10,7 і 3,2 %
