Shkoda O. Productivity of winter-rape depending on method of basic treatment of soil and fertilizers in the south of Ukraine

The object of researches is the processes of growth and development of rape of winter, forming of his productivity depending on the method of basic till of soil and fertilizer. The purpose of researches is establishment of basic constituents of forming of productivity of rape of winter at a different method basic till of soil and background of feed on the irrigated earths of south of Ukraine. Methods of researches - the field; analytical; the laboratory-field; computation-comparative; statistical. Results of researches - For a theory: First in the conditions of south of Ukraine on the irrigated livery to soil the features of growth, development and photosynthetic activity of rape of winter are trained, his productivity at application of straw of wheat of winter as an organic fertilizer at a different method of its bringing. For practice: Expedience of application of computation dose of mineral fertilizers, which provides high economic efficiency, is grounded. It is set, that bringing of computation dose of mineral fertilizers on the planned productivity of seeds of rape of winter 3 t/ha taking into account actual material well-being of soil by the elements of feed and biological necessity in them, that their recoupment promotes efficiency of fertilizers by the increase of harvest. The sphere of the use is the agricultural enterprises of south of Ukraine.
