Onufran L. Optimization of elements of technology of growing of the spring barley in Southern Steppe of Ukraine

The object of researches is Processes of growth and development of plants and forming of harvest of corn of spring barley depending on the elements of technology of growing. The purpose of researches is optimization of basic elements of technology of growing of modern sorts of spring barley, namely, terms of sowing, norm of sowing, application of fertilizers and defence of plants in the conditions of South Steppe of Ukraine. Methods of researches - the field; laboratory; statistical; computation-comparative. Results of researches - For a theory: First in the unwatering terms of South Steppe of Ukraine the optimum parameters of complex of elements of technology of growing of sorts of spring barley Stalker and Eney are definite. For practice: Are definite and recommended to production optimum terms of sowing and norm of sowing of seeds, application of fertilizers and defence of plants of modern sorts of spring barley, that productivity of corn enables to get in the conditions of south of Ukraine 3,2-3,6 t/ga.
