Zhuykov O. Agrobiological substantiation of complex of technologies of growing of mustard varieties in the Southern Steppe of Ukraine

The object of researches is Processes of growth, development and forming of seminal productivity, valuable signs and high-quality indexes of harvest of mustard of Chines (leaf) mustard and winter, white and black mustards depending on the technological receptions of growing. The purpose of researches is complex research of scientific and practical bases in relation to forming of seminal productivity, features of growth and development, adaptive properties and competitiveness of plants of mustard of different sorts and agrobiological grounds and development on this basis of complex of technological receptions of growing of cultures. Methods of researches - history; field brief one, two and threefactor experience; laboratory; computation; statistical; computation-structural, prognostication and design. Results of researches - For a theory: The first developed scientific and practical bases of growing of South of a new oil-bearing culture - mustards of black; the set maximum level of saturation of production by the types of mustard, that orients on impermissibility of exceeding of specific fate of culture in the structure of sowing areas; the done comprehensive agrobiological estimation of modern of high quality composition of cultures. For practice: The results of the noted researches make practical interest for the agricultural enterprises of region, that specialize on production of commodity mustard seeds and reproduction sowing material for own necessities. The sphere of the use is the agricultural enterprises of south of Ukraine.
