Alternate wetting and drying (Tar-Watar) is commonly practiced in many crops particularly in rice in Pakistan as usually flooded conditions are difficult to maintain through out growing season. This improves growth, yield and stabilize quality. Now rice is being propagated by direct seeded method in many parts, also irrigated by tar-watar method and under growing water scarcity in Pakistan, it will complement to existing water crisis in Pakistan and also to stabilize the rice prices including quality due to reduced cost of production.
