Abstract | Alternate wetting and drying (AWD) has been attracting increasing interest, because it seems to reach several useful objectives: using less water to achieve the same result; thus increasing water productivity and profitability. It is the most widely adopted water-saving irrigation practice in China. This method of irrigation is characterized by: a) mid-season drainage during the later tillering stage of the crop and b) periodic soil drying 2-4 days in between irrigation events from panicle initiation to the harvest. In the mid-season drainage, the soil is dried out for 10-15 days, depending on the weather condition until some fine cracks appear in the soil. |
