ABSTRACT
The authors studied cultivation technology with drip irrigation based on renewable water energy in comparison with furrow irrigation in two agro-ecological zones in south and southeast Kazakhstan. Three soybean varieties (Lastochka, Danaya, and Akku) were used in the study. Due to the uniform supply of water to the roots of plants, drip irrigation has a positive effect, as compared to furrow irrigation, on the quantitative characteristics of growth and development of soybean plants and the formation of productivity indices. The yield of soybean varieties (an integral index that depends on irrigation methods) increased for all varieties by 5.6-10.6 c/ha with the use of drip irrigation.
