Improving water productivity can make an excellent contribution to global food production and poverty improvement. The purpose of the study was to evaluate the water productivity, crop water use efficiency and irrigation water use efficiency of tomato cucumber and bottle gourd crop under water stress condition. A field experiment was conducted at the experimental site of Sher-e- Kashmir University of Agricultural Sciences & Technology, Srinagar, Jammu and Kashmir during 2018. The average yield of tomato, cucumber and bottle gourd was 30.65 ton/ha, 18.41 ton/ha and 19.15 ton/ha. The maximum and minimum yield for the tomato was 43.2 ton/ha and 12.31 ton/ha. The range of water productivity for tomato crop was 5.3 – 13.45 kg/m3. Crop water use efficiency varies from 36.59 – 125.65kg/ha/mm for tomato crops. The highest irrigation water use efficiency was 330 kg/ha/mm for tomato crops. The best result is obtained in case of treatment 11because irrigation was provided at the initial and development stage only. The crop needed more water in the initial and development growth stage. At mid and late-stage water is provided by the rainfall, so there is no need for irrigation at these stages. Similarly, range of water productivity and crop water use efficiency for cucumber crops found to be 6.59 to 15.75 kg/m3 and 24.53 to 80.96 kg/ha/mm. The highest irrigation water use efficiency for cucumber crop was found in treatment 14 (321.48 kg/ha/mm). For bottle gourd crop maximum water productivity (15.93 kg/m3) found in T9 and highest irrigation water use efficiency (272.43 kg/ha/mm) in treatment 11. Therefore, irrigating the field when the crop needs help to enhance water productivity and save the most precious resource water.
