A field experiment was conducted in Central Farm of OUAT, Bhubaneswar, to determine the water use efficiency of sunflower under deficit drip irrigation during the year 2018-19. Five treatment levels of irrigation i.e. at field capacity, 20 per cent, 40 per cent and 60 per cent MAD level of irrigation under drip irrigation method and one farmers practice under furrow irrigation method as control with 5 replications was considered for the experiment with RBD design. The maximum water use efficiency of 11.2 kg/ha-mm for sunflower was found in 40 per cent MAD level of drip irrigation followed by 10.89 kg/ha-mm in 20% MAD level of irrigation. The deficit drip irrigation produced 57.88% more sunflower yield consuming 26.83% less water at 40% MAD level over farmers practice. Considering the maximum water use efficiency, sunflower crop may be irrigated at 40 per cent MAD level by drip irrigation method for increasing the water use efficiency in East and South-East Coastal Plain Agro-climatic Zone of Odisha, India.
