Fedorovich G. Productivity and quality soryzu depending on level of crop rotation, seeding and power in southern Ukraine

The object of researches is the processes of growth, development of plants, forming of productivity and quality of corn of soryzu. The purpose of researches is the study of processes of growth and development of plants, forming by them the productivity and quality of corn of soryzu under act of predecessors and backgrounds of feed. Methods of researches - the field, laboratory, statistical and generally accepted in agriculture methods of concomitant researches. Results of researches - For a theory: First in the conditions of south of Ukraine influence of predecessors on the processes of growth and development of plants of not groats culture in current use of soryzu is explored, forming by her the productivity and quality of corn for growing on black earth a south both without the fertilizers, and the on a background improved their application. The nourishing mode of soil at growing of culture on different predecessors is definite, supplies of moisture, total vodopotreblenie, coefficient of vodopotrebleniya. For practice: It is explored, that soryz is a drought-resisting culture which even in unfavorable after weather terms years on different predecessors is able to form the permanent levels of productivity of corn with the high indexes of quality. It is set, that productivity of culture rises considerably, and the basic indexes of fertility of soil get better at bringing of organic and mineral fertilizers in the link of crop rotation. The sphere of the use is the agricultural enterprises of south region of Ukraine.
