Irrigation scheduling(when and how much to apply) is the primary tool to improve water use efficiency, increase crop yields, increase the availability of water resources, and contribute positive effect for the quality of soil and ground water. Field experiment was conducted for two consecutive years to determine appropriate scheduling of onion production. The experiment ware arranged in RBCD with four treatments (T1=125%MAD, T2=MAD, 75%MAD, and T4= Farmers practices) and replicated four times. The result shows that there is no significant yield difference between treatment of 100%MAD (12311.6kg/ha) with 445.2mm seasonal amount of irrigation water and 75% of MAD (12931.4kg/ha) with 333.9mm seasonal amount of irrigation water. The highest total yield (12931.4kg/ha) was obtained from 75% of MAD by applying 333.9mm of irrigation water and the lowest yield (9824.2kg/ha) was obtained at Farmers practice by applying 484.5mm depth of irrigation water. The highest water use efficiencies of 4.66kg /m-3 is recorded at 75% MAD and the lowest water use efficiency of (2.36kg/m3 and (2.03kg/m3) is recorded at 125MAD and Farmers practice. For onion production applying irrigation water at long interval reduce the yield and water use efficiency. Therefore, applying irrigation water at 75% manageable allowable depletion increase onion yield and water use efficiency.
