Description of research:

Partial root-zone drying (PRD) irrigation is a novel biological water-saving irrigation strategy. The physiological responses of various crops to PRD irrigation have been intensively studied. Most of these studies observed that PRD irrigation can increase water use efficiency (WUE) without significant yield reduction, compared with conventional deficit irrigation (DI) and full irrigation (FI).
