Chernichenko M. Productivity minitubers of potatoes at different r?gimes and way of the irrigation in the south of Ukraine

Object of researches - products processes of plants of potato from the minitubers of the sort Kobza at different terms moistening. Purpose of researches - theoretical ground of elements of technology of tiny irrigation and sprinkling irrigation at growing of seminal material of potato in the primary links of Receipt of seeds. Methods of researches - the field; laboratory; biochemical; chemical; statistical; computation-comparative. Results of researches - For a theory: First for the terms of south of Ukraine on a livery one, middling to clay soil the processes of Consumption of water of the plants of potato, got from minitubers at tiny irrigation and sprinkling irrigation, are studied. Conformity to the law of growth, development and accumulation of harvest of tubers is set by the plants of potato from minitubers at different terms moistening of soil, economic and power the use is grounded for watering of potato of tiny irrigation and sprinkling irrigation. For practice: On the basis of results of researches the scientifically grounded elements of technology of growing of plants of potato are offered from minitubers subject to the condition sprinkling irrigation and tiny irrigation, which provide productivity at the level of 40-45 t/ga for the economies of material and labour resources. The sphere of the use is the agricultural enterprises of south region of Ukraine.
