Putsenko D. The influence of irrigation ways, fertilizers and plant density upon the yield and fruit quality of sowing tomatoes

Object of researches - processes of growth, development and formation of a crop of fruits of sowing tomatoes and their quality indicators depending on investigated factors. The purpose of dissertational work - to develop a technological complex of cultivation of sowing tomatoes at different ways watered, norms of mineral fertilizers on the planned level of a crop and density of standing of plants at which formation of high and constant crops of high quality in conditions of an irrigation in the south of Ukraine is provided. Methods of researches: field - for definition of a level of a crop, biometric accounts and measurements, laboratory - structures of a crop and the analysis of quality of fruits; mathematics-statistical - carrying out of the dispersive analysis and statistical processing of results of experience; settlement-comparative - an estimation of economic and biopower efficiency of investigated elements of technology of cultivation of sowing tomatoes. Results of researches: 1) for the theory- new scientific data about growth, development and productivity of plants of sowing tomatoes of grade Rio Grande are obtained; 2) recommendations are developed for practice - on technology of cultivation of sowing tomatoes in conditions of an irrigation in the south of Ukraine that allows to receive a stable level of a crop of fruits of high quality. Sphere of use: substantive provisions of researches can find practical use in facilities of southern region, which are engaged in cultivation of sowing tomatoes in irrigated conditions.
