Zolotukhina Z. Productivity of winter wheat varieties depending on agrotechnical measures of cultivation in the conditions of Southern Steppe of Ukraine

Object of researches - processes of forming of productivity and quality of corn by the intensive sorts of wheat of winter under act of regulators of growth and different levels of nitric nourishment. Purpose of researches - to optimize a products process in relation to realization of biological potential of productivity and quality of corn of intensive sorts of wheat of winter through the use of regulator of the AKM growth on a background a different level of nitric nourishment in the conditions of South Steppe of Ukraine. The methods of researches are scientific, special, mathematic-statistical and computation-comparative. Results of researches - For a theory: First for the terms of South Steppe of Ukraine conformity to the law of products process of plants of wheat of winter depending on treatment of seeds and plants by the modern regulators of growth and application of different doses of nitric fertilizers for nourishment is set. Technology of the use of regulator of the AKM growth for the rise of productivity and quality of corn of intensive sorts of wheat of winter is developed. For practice: For the receipt it is assured high productivity and quality of corn of intensive sorts of wheat of winter for growing of them in the conditions of south Steppe of Ukraine, it is offered to apply the recommended dose of nitric fertilizers for providing of productivity of corn at the level of 6,0 t/ha and conduct before sowing treatment of seeds and plants in the phase of output tube and pouring of corn by the regulator of growth of the AKM plants. The sphere of the use is the agricultural enterprises of south of Ukraine.
