Bulygin D. Influence of the modes of irrigation and density of standing plants on the productivity of mid-season sorts of soy in the South region of Ukraine

The object of researches is the processes of growth and development of mid-season varieties of soy in the conditions of irrigation at different terms of humidity, density of standing and other factors of providing of vital functions of plants. The purpose of researches is development and improvement of elements of technology of growing of mid-season sorts of soy on the bases of resursosohraneniya in the conditions of irrigation in the South region of Ukraine. The methods of researches are scientific, special, researches, systems, mathematical-statistical, correlation, computation-comparative analysis, mathematical design. Results of researches - For a theory: The first given estimation of influencing of irrigation and density of standing of plants on productivity of mid-season varieties of the Danaya and Aratta soy at application of continuous method of sowing in droughty terms. For practice: has the important practical value for the economies, which are engaged in growing of soy in the conditions of irrigation and can be used for expansion, reconstruction and exploitation of irrigation systems, on the south of Ukraine. The sphere of the use is the agricultural enterprises of south of Ukraine.
