Berdnikova O. Winter Wheat Varieties Productivity Depending On Nutrition Backgrounds and Irrigation under the Condition of the South of Ukraine

The object of researches is Processes of growth, development of plants of sorts of wheat of winter and forming of productivity and quality of corn depending on mineral and mikroudobreniy and modes of irrigation on livery soil. The purpose of researches is development and scientific ground of basic agrotechnical receptions of growing of sorts of wheat of winter, in particular, influence of irrigation, mineral fertilizers and vnekornevih podpitok on their productivity in the conditions of South of Ukraine. Methods of researches - the field; laboratory; statistical; computation-comparative. Results of researches - For a theory: For the terms of South Steppe of Ukraine on livery middling loamy soil the influence of differentiation of terms of moistening, bringing of mineral fertilizers and conducting of vnekorenevih podpitok Kristalon and Tenso on productivity and quality of corn of sorts of wheat of winter is first studied. For practice: The elements of technology of growing of wheat of winter on the irrigated earths are improved, namely in the ground of expedience of application of mineral and mikroudobreniy in combination with the mode of irrigation of saving of water with the purpose of rise of productivity of corn of wheat of winter and his qualities on condition of optimization of the use of agrarian resources and saving of fertility of livery middling loamy soil. The sphere of the use is the agricultural enterprises of south of Ukraine.
