Pankieiev S. Productivity of Winter Wheat Varieties Depending on the Nutrition Background and Moistening Conditions in the South of Ukraine

Object of research - processes of growth, development, adaptive properties of plants, formation of crop and quality of grain of wheat varieties of winter, depending on biological characteristics, background of nutrition and conditions of humidification. The purpose of the research is to investigate the influence of the conditions of cultivation on the yield and quality of winter wheat grain in the south of Ukraine, to optimize the nutrient regime of the soil when cultivating winter wheat varieties for a stable grain yield. Methods of research - field; Laboratory; Statistical, estimated. Research results - For the theory: For the first time in southern Ukraine, the processes of growth, development, adaptive properties (frost resistance, resistance to falling) of winter wheat plants of Kherson Bezosta, Dryada, Victoria Odesa, Vdala, Favoritka, Alya saiga, Laguna, and their productivity formation were investigated. And the quality of the grain under the influence of the background in different humidity conditions. For practice: The application of the estimated dose of mineral fertilizers, which is determined by the difference between the removal, the optimal and actual content of moving nutrients in the soil, allows you to obtain the yield of wheat of wheat of winter varieties Victoria Odesa, Khersonskaya Bezosta, Dryad and Laguna without irrigation at a level of 4.27- 4.60, and at irrigation - 6.22-6.87 t / ha. Sphere of use - agricultural enterprises of the south of Ukraine.
