In the process of ontogenesis, corn plants need not only traditional nutrients of mineral nutrition, but also micronutrients, most important among them are: Zn, B, Mo, Co, Mn, Cu and others that play an essential role in the life of corn plants. That is why our scientific researches are devoted to the study of the influence of the calculated norm of mineral fertilizers (Check) on dark gray podzolic soils and the application of micro nutrients fertilizers Nutrimix, Nutribor and Micro Mineralis Corn as topdressingin two phenological phases with maximum 2times application. To fulfill tasks set during 2015-2017, research was carried out under conditions of LLC Ukrainian Dairy Company (Zgurivsky District, Kyiv region) with hybrids Orzhitsa 237 (control) and Ajax. The conducted researches and the substantiation of the received results defined optimal; rates of micronutrients Nutrimix (1 kg / ha), Nutribor (0.5 kg / ha) and Micro Mineralis Corn aqt the steges 4 and 8 leaves with mineral fertilizers N158P52K52 as check, which provided the formation of the maximal yield at an average of three years at the level of 9.29 t / ha in the Orzhitsa hybrid and and 9.95 t / ha for 237 MW. At the same time, the quality indicators of corn grain were determined and the patterns of change in the content of protein, starch and fat content from the applied fertilizers were revealed.
