Poltoretskyi S. Agrobiological basis of high-quality millet seed formation under the conditions of Right-Bank Forest-Steppes of Ukraine.

The research object is formation processes of seeds of different varieties of millet, its sowing qualities and yielding properties under the influence of abiotic and anthropogenic factors in conditions of Right-Bank Forest-Steppe of Ukraine. The aim was to determine optimal conditions for growing millet in Right-bank Forest-steppe of Ukraine, which will provide maximum yield of high-quality seeds. Research methods are laboratory, mathematical-statistical and calculating-comparative. The necessity of sowing millet seed crops in fertilized ground after fertilized predecessors of peas and winter wheat not later than the second decade of May by conventional line method and the rate of sowing 3,5 million similar seeds/ha is substantiated; positive effect of separate harvesting with obligatory softening wet weight of rolls at least three-six days on the formation of the highest level of quality indicators of seed material is proven; it is found that between the yield of millet seeds in generations there is a direct correlative connection while it is closely linked to laboratory, technological and cereal indicators of quality through integrated quality score of seed material and millet yield; feasibility of using integrated quality score for characteristics of sowing conditions of grown millet seeds in generations is determined; three patents for utility model are obtained. Implementation of copyright works is carried out into production in agricultural units of Cherkasy, Vinnytsia and Kirovograd regions. The research results are used in Uman National University of Horticulture and implemented into the educational process of other educational institutions of Ukraine. Field of use is selection research institutions and agricultural production.
