Role of Irrigationin Higher Crop Productivity

摘要

Water available in India, its consumptionpattern, potential of irrigation and actual irrigated area are given. The reasons for the gap between potential and actual are briefly mentioned. The role of irrigation and drainage in crop produotivity with data is presented and discussed. Improved metods of irrigation and their role in increasing yields and sustainability are reviewed along with actual data for several crops. Drip irrigation is discussed. Changes in methods of water resources management to commensurate with changing time are mentioned. Policies and strategies for such changes are also discussed in this paper.
