Netis V. Optimization elements of technology cultivation of soybean on irrigated lands of southern Ukraine

Object of research - processes of growth, development of plants and the formation of crop and quality indicators of seeds of different varieties of soybeans during irrigation, depending on the studied elements of technology. The purpose of the research is to optimize the main elements of the technology of cultivating the new generation of soybean varieties, namely: seed sowing, application of mineral and bacterial fertilizers, plant growth regulators and develop a varietal technology for their cultivation on irrigated lands of southern Ukraine. Research methods - field; laboratory; statistical; computational and comparative. Research results - For the theory: For the first time, the technology of cultivating soy varieties of the new generation Aratta and Sofia has been developed, which meets their biological requirements and gives the opportunity to maximize their crop potential, increase the productivity of the crop and the efficiency of its cultivation under irrigation conditions. For the practice: The optimum seed sowing, application of mineral and bacterial fertilizers and highly effective plant growth regulators for new soybean varieties have been determined and recommended for production, which makes it possible to obtain, in conditions of irrigation in southern Ukraine, seed yield of 3.0-3.2 t / ha and reduce costs of 10%. Sphere of use - agricultural enterprises of the south of Ukraine.
