The comparative study was conducted to evaluate the performance of low pressure drip irrigation system and manual hose irrigation in cowpea. Irrigation time optimized at 30minutes provided 500 ml of water per plant. Based on the growth stage, crop water requirement of vegetables was estimated to be 1 to 2.2 litre/day. To meet this crop water requirement, irrigation was done at 4 times intervals i.e., morning twice and evening twice in such a manner 2.2 litre water was irrigated per plant. Thus, drip irrigation conserved 70% water compared to manual hose irrigation. It was found that drip irrigation gave 33% higher yield than the yield obtained with the manual drip irrigation system. Overcoming severe drought, 1.18q/ha-cm water use efficiency was recorded in DIS. Low pressure DIS increased irrigation efficiency up to 95% than that of conventional method of irrigation
