The effect of different types of fertilizers on the yield of corn for grain in Tambov region

The article presents the results of research carried out in 2014-2017 studying the effects of liquid fertilizers Megamix for foliar nutrition of corn on the background of mineral nutrition. The work was carried out under conditions of long-term stationary field experience on typical Chernozem, in six-field crop rotation. The introduction of liquid mineral fertilizers Megamix in combination with the use of traditional mineral fertilizers and optimization of nitrogen nutrition on the typical Chernozem with high availability of mobile forms of nutrients has a positive impact on the yield of corn in terms of grain crop rotation. The maximum yield of maize grain on average for the years of research was obtained on the variant with autumn application of azofoski at a dose (NPK)60 in combination with the introduction of ammonium nitrate N60 (presowing cultivation) + Megamix (in the phase of 3-5 leaves) - 11.1 t/ha. Increase to control made up 4.82 t/ha. the Remaining variants of the experiment also significantly higher than the control.
