英文摘要	Traditional irrigation practices, low crop productivity, unlevelled fields, water losses taking place during conveyance and application phases, as well as low irrigation efficiencies are the main problems of the common farmers in Pakistan. These problems are more noticeable in the command area of Lower Chenab Canal (LCC), which is the main portion of the Indus Basin Project in Pakistan. To overcome these problems, different water management technologies such as precision land levelling (PLL), bed planting, drip irrigation systems, and watercourse improvement were introduced to farmers to increase water savings and crop yields in the area of five distributariesKhurrianwala, Shahkot, Mungi, Khikhi, Killianwala and Dijkotduring the cropping seasons of 2008 to 2015. The use of drip irrigation resulted in savings of water and fertilizer and increased the crop yields by 30-40%. Three watercourses, one on each site of 1200 m in length, were lined, which resulted in improved conveyance efficiency of 15-20%. If wheat, rice and cotton in the command area of LCC are sown on precisely levelled fields and on beds, then about 2768.1 million m(3) and 3699.3 million m(3) of irrigation water can be saved. These results show the potential of water-efficient technologies for saving water as well as increasing crop yields.
