Larchenko O. Optimization of higt-quality sift wheat (Triticum aestivum L.)in the southern Steppe of Ukraine

Object of researches - forming and achieving productivity and adaptive signs of wheat of soft a different type of development depending on the terms of Providing by moisture, terms of sowing, ecological point of test. The purpose of researches is optimization of high quality composition of wheat of soft on parameters ecological plasticity and stability of productivity for different terms of growing in droughty Steppe of Ukraine. Methods of researches - the field; laboratory; computation; mathematical; statistical. Results of researches - For a theory: First for the terms of droughty Steppe of Ukraine optimum of high quality composition of soft wheat of a different type of development for different is definite terms of sowing and terms of Providing by moisture. Scientifically grounded the use of sorts of a different degree of intensity, genetically and biologically heterogeneous, that allows effectively to use agroklimatic potential of every area, the fields and, in an eventual result, promotes productivity. For practice: Experimental data about the features of forming of productivity and quality of corn are got by the plants of winter wheat, which have the important practical value for the producers of seminal, food and commodity corn. The character of display of parameters of plasticity, stability and ecological firmness of adaptive signs, elements of productivity and productivity is definite at the sorts of wheat of a different type of development can be with success used in technological measures from the rise of agroekological potential of productivity of culture at different terms growing. The sphere of the use is the agricultural enterprises of south Steppe of Ukraine.
