  Irrigation is a vital practice in the Central Rift Valley of Ethiopia. However, water scarcity is the major limiting factor of agricultural production and productivity in the area. The field experiment was conducted on clay loam soil at the experimental field of Melkassa Agricultural Research Centre to evaluate the effect of furrow irrigation techniques and mulch types on onion yield and water productivity. The experiment was arranged in a split-plot design with three replications. The treatments include three furrow irrigation techniques (conventional, fixed, and alternate furrow irrigation) as main plot and mulch types (plastic and straw) and a control treatment of no mulch as sub-plot. The highest significant average bulb yield of 35.9 t/ha was obtained at the conventional furrow technique and the lowest average bulb yield of 24.6 t/ha was recorded at the fixed furrow irrigation te..
