The results of studies conducted over the 2011 2014 are demonstrated with identification maize hybrids for different ecological types of environmental stability realizing the potential productivity under conditions of northern part Forest steppes of Ukraine, and the establishment of their response to the growing technological measures. Determined that the yield of hybrids Polissya Forest steppe ecotype Zdvyzh MV and Trubizh SV less depends on weather conditions, than hybrids Steppe ecotype Orzhitsa 237 MV and especially Yarovets 243 MV. For the intensity of response to fertilization the best one was hybrid Zdvyzh MV, whose share of influence of the factor in formation the yield was highest (97.4%), and increases in grain were 0,44 7,47 t/ha.

Keywords: maize, hybrid, ecotype, fertilizer, method of protection from weeds, yield.
