Domaratskiy Y. Agroecological substantiation of the systemic use of multifunctional growth regulating agents in the cultivation of field crops in the Southern Steppe

Object of research - The process of scientific substantiation of agroecological and technological measures for the formation of yield and quality of winter wheat, sunflower and winter rape and the conditions of the Southern Steppe of Ukraine. The purpose of the research is theoretical substantiation and development of adaptive technologies for the optimization of the production processes of winter wheat, winter and sunflower rape, using modern ramming drugs in different conditions of cultivation. Research methods - field, laboratory, analytical, statistical, calculative and comparative-computational, statistical. Research results - For the theory: For the first time the adaptive properties of winter wheat varieties and hybrids of oilseeds have been determined by determining the plasticity and stability of the manifestation of yield under different growing conditions. The elements of technology of cultivation of investigated cultures that promote increase of productivity and quality of production independently from stress factors of an environment are developed. For practice: Foliar nutrition and the use of combined regenerating drugs provides more economical use of soil moisture reserves to form a unit of basic products; Thanks to the combined application of nitric fertilization and of the triglycerides, a direct synergistic effect was achieved; the use of biological stimulants increased the immunity of plants of winter wheat, winter and sunflower rape, and reduced the level of damage of agrocenoses by diseases by 25-40%. The sphere of use is agricultural enterprises of the south of Ukraine.
