The formation of grain productivity of maize depending on methods of cultivation

The researches’ results were represented along the influence of different mineral fertilizers’ doses and the plant density for yield of the grain of early ripe hybrid of the maize. It is established that with increasing of plant density the grain weight per cob was decreased. When making N120P90K60 the yield of the grain was increased by 2,00…of 2.78 t/ha. When using the fertilizers of the dose N120P90 the gain of the grain was received 39,7…48,8 % with comparison to unfertilized background. The shifting of the part’s nitrogen to the root feeding was contributed to the gain of the yield. 11,4…18,7 % in comparison with making of preplant N120P90. On the fertilized soil fertility the gain of the yield was marked until the density of 80 thousand/ha.
