FORMATION OF A PRECIOUS MASS OF STRAW WHEAT AND TRICHTICAL UNDER INFLUENCE OF THE OPTIMIZATION OF THEIR FOOD ON THE SOUTH OF UKRAINE

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. The said before information confirms that modern growth regulating substances are able to optimize the feed of summer crops and it is expedient to use them as an element of energy-saving technologies of graincrops growing in the conditions of Steppe of Ukraine. It is set that forming of the grain-growing productivity of summer grain-crops considerably grows in the condition of optimization of moisture providing to the plants due to atmospheric during a vegetation period. 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. Researches have established that a high efficiency of their application for early exit tube plants, and the two-time processing of crops by substances provides them a getting of the same level of grain yield, as the same as the their nutrition by nitrogen at a dose N₃₀. It is determined that in a southern steppe of Ukraine the level of productivity of crops, a.o. summer grain crops, which are largely determined by the amount of precipitation that rain during the growing season crops. By optimizing conditions of nutrition of plants significantly increases their productivity regardless of weather and climate conditions
