Naumov А. The productivity of carrot depending on irrigation techniques and modes of microirrigation and dozes of fertilizer on loam sandy soils of southern Ukraine

Object of researches - technological process micro irrigations of carrot in the conditions of Dry Steppe of Ukraine. The purpose of researches is the improvement of elements of technology of growing of carrot in the conditions of Dry Steppe of Ukraine, that includes a method, mode micro irrigations and dose of mineral feed. Methods of researches - the field; laboratory, abstracting; statistical; computation-comparative. Results of researches - For a theory: First for the terms of Dry Steppe of Ukraine at different methods micro irrigations productive potential of carrot is set, conformity to the law of forming of harvest and quality of root crops is definite on black earth a south depending on the modes micro irrigation and doses of mineral feed. Technology of growing of culture by optimization of factors is improved "method of watering" - "mode of irrigation" - "dose of mineral feed". For practice: Development for the economies of Dry Steppe of Ukraine at micro irrigation most economic of the expedient mode of irrigation of carrot in combination with the optimum dose of mineral feed, that t/ga is instrumental in forming of productivity of root crops at the level of 75-85. The sphere of the use is the agricultural enterprises of south of Ukraine.
