Vozhehov S. Theoretical and agroecological justification technologies of growing crops in rice crop rotations

The object of research - the formation of rice productivity and related crops. The purpose of research - theoretical and agroecological substantiation of technology of cultivation of crops in rice crop rotations southern steppes of Ukraine. Research Methods - general methods: analysis, synthesis, observation, comparison, measurement, etc; special: field, laboratory and field, laboratory; generally accepted scientific methods certified, GOST; statistical and cash-comparative. Results of research - theory for the first time in the conditions of South Steppe of Ukraine on different soils The dynamics of water and nutrient regimes in rice cultivation and related crops in crop rotation, irrigation regimes modeling made of rice using information tools established dynamic compilation density of the soil, weed-infested fields in rice crop rotations. For practice, research results is a scientific and practical basis for developing a rational use of primary tillage and fertilizer in rice crop rotations Ukraine taking into account regional factors with implementation of agri-designed resource saving measures. Agrotechnological development measures proposed rysosiyuchym farms, contribute to reducing the chemical load on rice agrocenosis and improve the ecological state of rice irrigation systems. Scope - farms south of Ukraine.
