Muntian L. The productivity of winter wheat varieties on seeding and fertilizing in rice crop rotations in the Southern Steppe of Ukraine

The object of research - the growth, development and yield formation of winter wheat, when grown under conditions of rice rotation, depending on the variety, seeding rate of seeds and doses of mineral nitrogen fertilizers. The purpose of research - theoretical study and improve the technology of growing winter wheat in the conditions of rice rotation Krasnoznam'yanskoyi irrigation system and obtaining high-quality grain when growing varieties of intensive type. Research Methods - Field; laboratory; statistical; settlement and comparative. The research results - for theory: first for the conditions of rice rotation the processes of formation of a crop of winter wheat of intensive type that is most adapted to growing conditions in rice crop rotations, depending on seeding and doses of nitrogen fertilizers. For practice, developed and improved the technology of growing winter wheat in irrigated rice crop rotations southern steppe zone, which in terms of regional climate change gives a yield of grain at 5,65-6,32 t / ha containing 11,4-12,2 % 17,3-21,6% protein and gluten, high levels of economic and energy efficiency. Scope - farms south of Ukraine.
