Water is becoming more precious commodity than anyone commodity, which is used for household activities, industry and agriculture across the world. Since rice is a staple food for the entire world. Due to the geometrical progression of the human population, the consumption of water is increasing day by day screening crucial limiting factor in all over the world. In this limiting available situation, the need of food to the world population by essential by increasing the rice production with new technologies which are enhance the food grain production by less available water. About 84 percent of water withdrawal is for agriculture, with major emphasis on flooded rice irrigation. Alternate wetting and drying irrigation (AWDI) with field water tube is a best water management technology in irrigated lowland rice that saves water and reduces greenhouse gas (GHG) emissions, number of irrigation and pest and disease while maintaining yields.
