Siroshtan A. Improving system of winter wheat seed production by the way of optimization of agronomical practices under environments of Right-bank Forest-steppe

Object of study - the process of formation of yield and sowing qualities of seeds for winter wheat. Purpose - improvement of elements of growing winter wheat seeds depending on agronomical practices under environments of Right-bank Forest-steppe. Research methods - field, laboratory, measuring, weight, morphophysiological, mathematical statistics, calculative and comparative. The peculiarities of formation of yield and sowing qualities of elite seeds for winter wheat varieties depending on complex of agronomical practices have been ascertained. The expediency of application of modern insecticides, fungicides, micronutrients in spring and summer on winter wheat seed crops has been demonstrated. Elements of technology of growing winter wheat seeds in farms of Right-bank Forest-steppe providing 6.56-7.74 t / ha of elite seeds with high seeding qualities have been improved. Production test and implement of elements of seed technology have been realized during the 2009-2011 in the farms of Kyiv region total area of 180 hectares. Field of use - agricultural production.
