Essay

In experiments which were conducted in 2001-2004, the influence of plants standing density and level of mineral nutrition on the terms of growth and development of different corn hybrids, productivity of corn, economic and energy efficiency of its production. Corn hybrids of Ukrainian selection (FAO 240-260): Uvileynuy 70 M and Desna SV is necessary to sow with plants standing density of 70 th./h, "Pioneer" company hybrids(FAO 260-275) PR39D81 and PR39R86 - 80 th./h. Phosphoric-potassium fertilizers is better to applicate under basic soil tillage, 90 % - nitrogen fertilizers under pre sowing cultivation and 10 % - as additional fertilization at he stage of 5-7 leaves; the recommended norm of mineral fertilizers on the planned productivity 8 t/ga - N120P90K90. Corn hybrids of the intensive type PR39D81 and PR39R86 recommended for industrial usage, will give possibility to promote productivity of corn on 25-30 %.
