Shevel V. Shaping to productivities and quality of grain varieties millet depending on sowing dates and background of fertilizer in condition of South of Ukraine

The object of research - the formation productivity millet varieties at different sowing time and doses of mineral fertilizers, especially the interaction of these factors in unirrigated conditions of southern steppe of Ukraine. The purpose of research - the study of the processes of growth and development of plants, forming their yield and grain quality millet varieties under the influence of sowing and backgrounds supply. Research Methods - field, laboratory, billing, statistic. The research results - for theory: the first time for conditions of southern steppe of Ukraine developed elements of technology of cultivation of millet, which provide formation performance culture through new domestic high-performance varieties adapted to arid conditions, reducing costs by minimizing chemical load using the estimated dose of fertilizer and optimal term sowing. For practice, developed and introduction into production of millet cultivation technology, which ensures the formation of grain yield at 3,8-5,3 t / ha through a combination of variety, sowing time and dose of fertilizer in unirrigated conditions of southern steppe. Scope - farms south of Ukraine.
