Karashuk G. Productivity and quality of a grain sorice depending on mineral fertilizers in conditions of irrigation of the south of Ukraine

Research object:: sоrice. The purpose of research: to teach (learn) processes of growth and development of plants, productivity and parameters of quality of a grain sоrice depending on a nutritious mode of a ground. To establish optimum, economically justified doze of mineral fertilisers under sоrice in conditions irrigation of a southern zone of Ukraine. Methods of researches: field short-term experience, and also techniques, standard in agriculture, of accompanying researches. Results of researches: 1) for the theory - for the first time for conditions irrigation of the south of Ukraine the carried out (spent) researches, which are directed for definition of influence of different dozes of mineral fertilisers on efficiency of culture and quality of a grain, growth and development, photosynthetic activity of plants, nutritious mode of ground, offset of basic elements of a feed(meal), irrigation sоrice. The optimum doze of mineral fertilisers is established which is determined by a settlement method,that has ensured on dark - chestnut obtaining to ground of the planned grain yield with high contents in it (him) of fibre and irreplaceable amino acids. Are carried out (spent) an economic, biopower and ecology-economical estimation of efficiency cultivation sоrice; 2) for practice - the application in manufacture of a settlement doze of fertilisers, which define (determine) behind a difference between offset, optimum and actual contents of mobile elements of a feed (meal) in ground, will ensure 65-70ц/га of a high-quality grain with significant economic and power parameters and ecology-economical benefit. Sphere of use: facilities (economy) of different patterns of ownership with cultivation agricultural of cultures in conditions irrigation.
