Revtio M. The formation of highly productive perennial grass agrocenoses on southern steppe arable lands withdrawn from tillage

Object of researches - Process of forming of harvest of seyanih mono specific agrofitotsenoz ovsyanitsi of east and alfalfas and weed specific to the овсяницево-alfalfa the mixtures of herbages depending on the norms of sowing. Purpose of researches - to Ground the theoretical bases of the modern landscape-ecological state of agricultural lands of south Steppe and develop energosohrannie technologies of creation of highly productive agrofitotsenoz of many years herbages in the conditions of the natural moistening. Methods of researches - analytical, field, laboratory, comparative-computation. Results of researches - For a theory: First at creation of highly productive agrofitotsenoz on the earths, withdrawn from till, productive potential of a new rannespelogo selection variety of ovsyanitsi is definite east (Dominique) and alfalfas of the Veselka sorts and Poltava, features of their growth and development depending on the agrotechnical terms of growing and influencing of prirodno-klimaticheskih terms of region. For practice: The got results of researches and developed agrarian-technological measures will find the practical use in the economies of different forms of own at zalugenii the arable earths withdrawn from till, and semenovodcheskih economies with the purpose of receipt of standard seeds of ovsyanitsi east. The sphere of the use is the agricultural enterprises of south region of Ukraine.
