　　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.
