Kazanok O. Productivity of sorts soybean, depending on irrigation schedules and backgrounds food in southern Ukraine

The object of researches is Processes of growth, development of plants of soy and forming of quality of corn of culture. The purpose of researches is Development and improvement of separate elements of technology of growing of soy in the conditions of south of Ukraine. Methods of researches - the field; laboratory; statistical; computation-comparative. Results of researches: 1. For a theory - First for the terms of south of Ukraine influencing of computation dose of fertilizers compatible with the оut of root additional fertilizing is explored by complex microfertilizer during differentiation of terms of moistening on productivity and quality of corn of soy of the Diona sorts and Apollo. Subsequent development of question of influencing of terms of the optimum mode of irrigation by rainwatering was acquired on the indexes of consumption of water and evaporation, bearing-out of elements of feed by the sorts of soy, rostovie and products processes of the explored plants. 2. For practice - Conducted researches allowed to define the optimum parameters of basic technological receptions of growing of soy on conditions of irrigation by rainwatering, which have a large practical value. The developed elements of technology of growing of soy of the Diona sorts and Apollo enable to get productivity of corn at the level of 2,8-3,5 t/ga. A net income here makes 3754,82- 4229,48 UAH./gа. The sphere of the use is the agricultural enterprises of south of Ukraine.
