The influence of various irrigation methods on the soybean water consumption rates and yield has been studied. It was established that the yield of the Lastochka soybean variety using the drip irrigation was 52.6 c/ha under the conditions of the Ili Alatau and 49.6 c/ha in the Kyrgyz Alatau, which is 8.0–8.14 c/ha more than when using the furrow irrigation. In both zones, the soybean consumption rates depended on the soil-hydrogeological state of the land.

Soy Cultivation Technology with Gravity Drip Irrigation in South and Southeast Kazakhstan

The authors studied the 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 on the quantitative characteristics of growth and development of soybean plants and the formation of productivity indices, as compared to furrow irrigation. The yield of soybean varieties (an integral index that depends on the irrigation methods) increased for all varieties by 5.6–10.6 c/ha with the use of drip irrigation.
