of irrigation and water use efficiencies to produce onion. It was carried out at Mekelle
Agricultural Research Center, Ethiopia on 70 m long and 0.6 m center–center spacing
furrows of 0.26% average slope on a clay soil. The treatments consisted of factorial
combination of two discharges (Q 1= 1 l/s and Q 2= 2 l/s) and three-cycle ratios (CR 1= 1/3,
CR 2= 1/2, and C= 1 for continuous irrigation). Surge flow treatments advanced faster than …
