THE INCREASING OF PRODUCTIVITY OF SUMMER GRAIN CROPS BY OPTIMIZING PLANT NUTRITION IN THE CONDITIONS OF UKRAINE SOUTHERN STEPPE

In this article are shown the results of researches about the study of efficiency of treatment of sowing summer wheat and triticale by modern growth regulating substances in the conditions of south steppe of Ukraine on the south black soil. It is experimentally well-proven that application of the said before mean of bringing a not high dose of mineral fertilizers – N₃₀Р₃₀ to sowing practically provides the receipt of the productivity of grain at the same level, as well as realization of signup the nitrogen (urea) fertilizer in a dose N₃₀. It is set that summer wheat and triticale, substantially promote the grain-growing productivity by applying of mineral fertilizers. Thus, by the background of making N₃₀Р₃₀+ N₃₀ in nutrition early exit tube plants in summer wheat on average for two years are formed 3.07 t/ha, while without fertilizer 1.57 t / ha and triticale under 3.47 and 2.07 t / ha. Proper treatment provides increase of crops yield of studied summer crops by means of modern growth regulating substances escort and D2
