Petrychuk L. Agrobiological bases of formаtion of highly productive agrocenoses sorghum sugar in terms of the Southern Steppe

The object of researches is the processes of growth, development, forming of harvest mono specific and compatible sowing of sorghum of saccharine depending on agro technological measures. The purpose of researches is the study of conformity to the law of forming of harvest of mono- and polividovih agrotsenozov sorghum of saccharine depending on the group of ripeness of district sorts and hybrids, optimizations of elements of resursosberegayushih technologies, that are instrumental in more effective use of biological features of green crops. Methods of researches - the field; analytical; the laboratory-field; computation-comparative; statistical. Results of researches - For a theory: First in the conditions of the natural moistening (without irrigation) in south part of area of Steppe the processes of forming of harvest of highly productive sorts and hybrids of sorghum of saccharine are explored. The set conformity to the law of forming of harvest of highly productive agrotsenozov sorghums of saccharine in the monospecific sowing depending on the method of sowing, densities of standing of plants and inokulyatsii seeds before sowing by bacterial preparations. For practice: As a result of the conducted researches improved and the elements of resursosberegayushey technology of growing of sorghum of saccharine are offered to production in the odnovidovih and compatible sowing in the conditions of the natural providing by moisture of south part of area of Steppe. The sphere of the use is the agricultural enterprises of south of Ukraine.
