Kharchenko G. Improvement of technology of growing potatoes for food under irrigation in the South of Ukraine

Object of studies: potatoes on the irrigated dark - chestmet soils. Purpose of studies: to put the finishing touches to the complex of the main elements of technology of growing of food potatoes on the irrigated lands of the Southern Ukraine which essentially influence the increasing of crop productivity. Methods of studies: system approach to the analysis of large information massives; field experiment, biometric, agrochemical and agrophysical observations; statistic grounds with using of generally excepted methods of mathematic statistics. Rezults of studies; 1) for theory - obtained rezults of investigations in response of potatoes plants on the created conditions of growth and development can be used for the formation of models of potatoes productivity. 2) for practice - adoption in industry of suggested regimes of irrigation, fertilizers and methods of the main soil tillage will make it possible to stabilize yield productivity of potato tubers, to raise the net profit from hectare of sowings, to provide competitive ability of potatoes comparison with traditional crops of the South of Ukraine. Field of utilization: farms of different forms of property in the South region of Ukraine.
