Abstract

Abstract: Drought interferes with soybean growth processes and causes significant changes to root system development and related physiological processes, thus reducing crop yield. Irrigation can mitigate drought effects on soybean production. This review focuses on the soybean root system; effects of drought on soybean growth processes are elaborated, the root system distribution and the mechanisms of physiological change following drought are discussed, and positive effects of appropriate irrigation on soybean crop development are indicated. Tactical irrigation strategies aimed at minimizing the loss of soybean yield caused by drought and achieving increased water use efficiency are discussed, and the emerging directions and status of soybean research in drought prone regions are reported. This paper thus provides a theoretical basis for future research into drought-resistance of soybean, and is of significance to achievement of water savings, drought-resistance and yield increase of soybean grown in drier areas.

Key words: research progress, drought, soybean, growth and development of root, irrigation
