Comparison of Tape Drip Irrigation and Furrow Irrigation Systems on Base of Water Use Efficiency and Yield of Potato in West of Iran

Potato is a major crop of Kermanshah province but shortage of water is important its production. To investigate yield and water use efficiency of potato with trickle (T-Tape) and furrow irrigations, an experiment was performed in Kermanshah agriculture university research farm in 2007. The experiment was in complete randomized blocks design with 3 levels of irrigation-water amount (50%, 75% and 100% of cumulative evaporation from Class A pan) and irrigation methods (tape and furrow irrigations) with 3 replications. The results indicated that regardless to irrigation method, the maximum yield of potato (34.455 ton/ha) was achieved in irrigation water treatment of 100% and the minimum yield of potato (19.168 ton/ha) was achieved in irrigation water treatment of 50%. The effect of irrigation method on dry matter was not significant, but with reduction of irrigation water, the specific gravity of tubers of potato was decreased.
