Sidorenko A. Productivity and quality of grain varieties of winter wheat depending on the norms sowing and providing by nitrogen

Object of researches - Processes of forming of productivity and quality of corn at the sorts of wheat of soft winter and parameters of complex of elements of agro technology, which adapt oneself to their agrobiological features in the conditions of Central Steppe of Crimea. Purpose of researches - to define influencing of norms of sowing and material well-being by nitrogen on productivity and quality of sorts of wheat of winter in the unirrigated terms Central Steppe of Crimea. Methods of researches - the field; laboratory; statistical; computation. Results of researches - For a theory: First in the conditions of Central Steppe of Crimea the character of forming of harvest and quality of corn of sorts of wheat of winter, which differ by ecological plasticity, is explored, depending on complex action of norm of sowing and dose of nitrogen, their parameters are adapted. For practice: Zemlyachka Odessa, Unity, Kiriya norms of sowing, doses of nitric fertilizer, doses of Nourishment out of root and terms of application of fungicides are adapted to the terms of the Steppe area of Crimea agrobiological features of sorts of wheat of winter provide the receipt to 50,1-58,6 с/ga high-quality corns. The sphere of the use is the agricultural enterprises of south of Ukraine.
