Abstract:

Water is scarce resource in Central Rift Valley of Ethiopia and is major limiting factor for crop production. Onion is one of the major economically important vegetable crops grown under irrigation in central rift valley. The field experiment was conducted at Melkasa agricultural research center during the off-season to identify irrigation method and irrigation application level that maximizes productivity of onion per unit of water consumed and enhanced onion crop production. The experiment was carried out using split plot design in RCBD having six treatments with three replications. The experiment consisted of two irrigation methods viz., furrow irrigation and drip irrigation as main plot and three levels of Manageable allowable depletion viz., 120%, 100% and 80% of manageable allowable depletion as sub-plot. The analysis of variance revealed that irrigation methods and management allowed depletion levels had a significant (p
