Irrigation scheduling is a critical management input to ensure adequate soil moisture for optimum plant growth, yield, quantity, water use efficiency and economic return. Present study was conducted to find out the water use efficiency and economic return of onion at Sam Higginbottom University of Agriculture, Technology and Sciences, Allahabad. The study revealed that the total cost of production increased slightly with increase in irrigation levels due to insignificant increase in pumping cost induced by variation in seasonal water applied. The total cost of production in drip irrigation was considerably higher as compared with micro-sprinkler irrigation method mainly due to the variation in irrigation system cost caused by large number of dripper/ha and lateral length. The gross return increased sharply from 50 to 125% pan evaporation replenishment decreased the gross return due to decrease in crop yield. The net return increased sharply from 50 to 125% of pan evaporation replenishment due to sharp increase in crop yield. The benefit cost ratio of onion for all three irrigation methods increased considerably from 50 to 125% of pan evaporation replenishment due to sharp increase in gross return. The maximum benefit cost of onion for drip (16.31), for surface (13.86) and for micro-sprinkler (21.0) was obtained at 100% of pan evaporation replenishment. Surface irrigation give higher benefit cost ratio as compared with drip irrigation and micro irrigation mainly due to lower system cost.
