Water use efficiency and physiological response of rice cultivars under alternate wetting and drying conditions

摘要：

　　Rice production in Asia is increasingly constrained by water limitation as a consequence of global water crisis.One of the technology options that can help farmers cope with water scarcity at the field level is alternate wetting and drying (AWD).Nitrogen (N) is also an important factor which often interacts with water and influences rice growth.
