Umanskiy O. Development and a substantiation of elements technology of cultivation of a soya in a rice crop rotation (for conditions of Krasnoznamenskoy irrigating system)

The object of researches is the culture of soy in the conditions of rice crop rotation. Purpose of researches - to develop the basic elements of technology of growing of soy in the conditions of rice crop rotations. Methods of researches - the field, laboratory, biochemical, chemical, mathematic-statistical, computation-comparative. Results of researches: 1. For a theory - first for the specific terms of rice crop rotations of south of Ukraine is offered and approved culture of soy; the best sorts of culture are set, the optimum mode of irrigation of soy is definite; the system of defense of sowing of soy is improved from weeds and the doses of mineral fertilizers at growing are definite; the parameters of optimum width of spaces between rows on sowing of soy acquired subsequent development. 2. For practice - are developed recommendations to the rice economies to rear the sorts of soy of different groups of ripeness with space between rows 30 sm. Thus to bring in the mineral fertilizers by the dose N60P90, to conduct one watering in the phase of flowering of culture, to apply herbicide of dual gold 960 ES to sowing of culture by a norm 1,6 l/ga and bazagran in the period of vegetation of soy by a norm 2,0 l/ga. The developed elements of technology allow to get the stable harvests of soy at the level of 22,8-33,9 ts/ga, that promotes efficiency of the use of the irrigated earths due to high profitability of culture and saving of fertility of soils. The sphere of the use is agricultural enterprises.
