Homina V. Reaction of a breed and productivity of a buckwheat depending on influence of regulators of growths in conditions of a southeern part of the western Forest-Steppe of Ukraine

object - the process of forming productivity of buckwheat depending on different of biological and morphologocaly of sorts, metods of sowing, regulators of growth at the different ways and terms of their use and feature of their co-operation in the soil-climatic time thier use peculiarly their interaction in the dirt-climatic factors of region; puprose - to expose the reaction of different sorts of buckwheat on the used regulators of growth, the setting most effective regulators of growth, and way or time of their use for improved yield and improvement factor grain of buckwheat in the conditions of southern part of Western Forest-steppe of Ukraine; metods - generel scientific: hypothesis, experiment, supervisions, special: field, measuring-weight, weight, mathematical-statistical; novelty - for cultivation of buckwheat in the conditions of southern part of Western Forest-steppe of Ukraine to expose the most effective regulatorsof growth with the purpose of rise of productivity of this culture are exposed, and also set the best metods to heighten productivity this culture, and also to discover most way and optimum time of use preparatins to seed sorts reaction of buckwheat by spring and summer times of sowing; results - the best regulators of growth are exposed near to growth different sorts of buckwheat by factor of region; to develop recommendations regarding to way and time used preparations, which is helped increase yield and improvement gualities grains of buckwheat; introduction - the agricultural enterprises of the Chernovitsiy and Khmelnitskiy reggions on the general area 160 ga; research - agriculture.
