Il’enko A. Optimization of adopting forming of the productivity of soy of different groups of ripeness in the conditions of northern of Steppe of Ukraine

An object is a process of the productivity and corn quality forming of soy sorts of different ripeness groups under influence of different density and nutrition area of plants. Purpose – to develop more accomplished receptions of growing agrotechnic of soy sorts of different ripeness groups. Methods – laboratory, field, and laboratory-field experiments. Results: the agrotechnics of Oriana and Phaeton soy sorts are developed and allow in the conditions of north Steppe of Ukraine to provide the productivity of seed of 2,1-2,3 tons per hectare. Novelty: firstly for the conditions of north Steppe of Ukraine the basic receptions of growing technology of modern soy sorts of different ripeness groups are developed. For the conditions of zone found out the reaction of plants on agrotechnical receptions. Found out the adaptive functions of plants of soy sorts of different ripeness groups. The field of introduction: Agriculture.
