Sviridovsky V. Influence of regime irrigation and protection of plants on the productivity of onion in Southern Ukraine

The object of research is the processes of formation of the onion of onions, depending on the agrotechnical measures in growing in conditions of drip irrigation in the south of Ukraine. The purpose of the research is to develop agrotechnical measures for growing onions in the conditions of drip irrigation in the south of Ukraine. Methods of research - field, laboratory; statistical; computational and comparative. Research results - For the theory: For the first time, under conditions of irrigation in the south of Ukraine, the processes of formation of the productivity of plants onion on the basis of interaction of drip irrigation and plant protection products have been investigated. Influence of irrigation regimes and different protection schemes of plants on their productivity was established, mathematical models of formation of crop of the studied culture were developed. For the practice: According to the results of the study, the elements of the technology of growing onions of a diced irrigation method in southern Ukraine have been improved and proposed for production. The sphere of use is agricultural enterprises of the south of Ukraine.
