Bondarenko V. Improvement of a technology of growing of spring canola in conditions of irrigation in the south of Ukraine.

Object of researches: spring canola. The purpose of researches: to base scientifically and create the complex of agrotechnical methods of growing of spring canola on irrigated land of the south of Ukraine, that will provide the getting of guarantee high yields of its seeds at economical use of resources.comparatively-calculative, mathematical. Results of researches: 1) for the theory - for the first time in the conditions of the south of Ukraine was determined the action and interaction of irrigation regime and doses of mineral fertilizers on the yield and quality of goods seeds of spring canola, total use of water and overage day evaporation, nourishing resume of soil; 2) for practice - the experimental material gave the opportunity to base economically and to recommend for the production the regime of irrigation of spring canola with optimal ensuring of plants by nourishing elements; was determined the term of gathering of this crop for seeds and green mass; were fixed the most adaptive sortsof spring canola for growing in conditions of south Steppe The data, that had been got, are promote the increasing of yield and quality of canola seeds, receiving of ecology - clean output. Sphere of use: the different forms of agricultural managing with growing feeding of cultures in conditions irrigation.
