ABSTRACT: There are results of research on the effectiveness of new and improved elements of potato cultivation technology applied to the soil and climatic conditions of a foothill zone in the south-east of Kazakhstan. It has been established the influence of various precursors in crop rotations, irrigation technologies, new varieties of potatoes and fertilizer systems on yield, quality and keeping capacity of tubers. It was found that the productivity of a potato has increased by 33,7-39,8% when placing at the best predecessors in crop rotations, by 9,02-12,89% when using water-saving technologies, in the selection of highly productive varieties by 12,5-19, 6%, and while improving the conditions of mineral nutrition - from 18,6 up to 47,3%.
