This article describes the specific conditions of nutrition of adaptive hybrid corn with ears to obtain high planned yields in the phase of milk-wax ripeness of grain on the gray forest soil of the Volga region of the Republic of Tatarstan in 2013-2015. As a result of the research it was found that the maximum increase in the area of the leaf surface was formed against the background of application of the calculated doses of fertilizers on 70 t/ha with sowing of corn hybrid Flint 200 (30.71 thousand tons). m 2 /ha), greater accumulation of plant biomass on the same background was observed on crops using the Newton hybrid (33.0 t/ha). The maximum yield formation (to 65.3 t/ha) was observed when making NPK 70 t/ha and the sowing of hybrid Newton, yield of green mass of corn on the background without fertilizers depending on sown hybrids amounted to 34.3-38.4 t/ha. In addition to this embodiment, it is noted the best nutritional value food and the best profitability 39.2 per cent, against 24.8 per on the background without fertilizers.
