Combining alternate wetting and drying irrigation with reduced phosphorus fertilizer application reduces water use and promotes phosphorus use efficiency without yield loss in rice plants

As one of the most widely promoted effective irrigation strategies for rice, alternate wetting and drying (AWD) irrigation can not only reduce water use but also increase mineral nutrient use efficiency. In this research, we compared the differences in grain yield, grain quality, phosphorus use efficiency (PUE), and growth states of roots and shoots of lowland and upland rice cultivars that were subjected to different irrigation and phosphorus...
