In irrigated as well as in rainfed areas, it is essential to work on the increase in water/ moisture-use efficiency of the crops. Since water is precious, suitable methods of irrigation and in-situ moisture conservation practices are to be adopted by the farmers on the basis of the suggestions made by the agricultural scientists of the country. In rainfed areas, suitable tillage can play a significant role in the conservation of moisture. Selection of crops and their varieties, fertilizer management and proper methods of sowing are the factors for increasing the moisture-use-efficiency and productivity. Methods of irrigations are to be modified in irrigated areas mainly to check the unnecessary loss of water.
