Nepochatov M. The optimization of main elements for growing technology of modern cultivars of bread winter in conditions of the east part of the Forest-Steppe of Ukraine

Object: tools of the provision for grain yield stabilization and grain quality of winter bread wheat in the conditions of the eastern part of the Forest-Steppe of Ukraine. Aim: to establish some peculiarities of the optimization main elements to technologies modern cultivars of winter bread wheat in the conditions of the eastern part of the Forest-steppe of Ukraine. Methods: field, laboratory, comparative-calculated, thermostatically- weighted, statistical. Novelty: for the first time for the conditions of the eastern part of the Forest-steppe of Ukraine new cultivars of winter wheat are selected for a adaptability type to weather condition, intensity level under cultivation on various fertilizer background, which provide a competitive productivity and quality of grain. For the first time, as for the conditions of the eastern part of the Forest-steppe of Ukraine, is determined rates of main elements of mineral fertilizer usage per on unit of produce and factors of their use by new cultivars of winter wheat. It is high-quality growing technology of winter wheat cultivars winter wheat advanced and economic ally motivated. Results: The most are determined adapted to the conditions of the eastern part of the Forest-steppe the winter wheat cultivars Harus, Belosnejka and Columbia for sowing on black fallow, Astet, Vasylyna and Columbia - after peas for grain. The rates of the fertilizer elements at sowing cultivars on black fallow and at sowing after peas for grain are defined. The sowing dates for winter wheat depending on a fore crop are established. The rates of the herbicide, fungicide and insecticide application integrated of protection winter wheat's sowing from harmful organisms. Application stage: the advanced elements of growing technologies are included into recommendations " Growing winter cereal crops on the farms of Kharkiv region in 2007 (an autumn complex of the field practice)". The results of the studies are introduced in to SEEF "Elitne" of Yuryev Plant Production Institute, NAAS and EF "Svitanok" on the total area of 95 ha that has provided grain yield increase of winter wheat by 0,4-1,0 t/hа in comparison with the traditional technology. Application area: agricultural enterprises of all property categories.
