To evaluate the effect of water, tape drip and furrow irrigation methods on the performance components and features of Agria cultivar potato, an experiment was carried out in the agriculture faculty of Kermanshah. Repeated three times, this study was carried out in the form of full random blocks with the main factor of different amounts of irrigation water in three levels (50, 75, and100 percent of cumulative evaporation from an A- class evaporation pan) and the secondary factor of irrigation method (including drip and furrow irrigations). At 3 repetitions, results showed that the minimum performance (19.168 tons per hectare) was related to the drip irrigation method with 50 percent evaporation from the A-class pan and the maximum one (34.455 tons per hectare) was related to the drip irrigation method with 100 percent evaporation from the A-class pan. The rate of irrigation and effectiveness of method on the number of the main stem per square meter and number of the main stem in the bush were not significant. The minimum percent (number of tubers) of tubers smaller than 35mm (26.47percent) and the maximum tuber production (37.17 percent) in the size of food and market-friendly (tuber bigger than 55mm) were attained by drip irrigation method with 100 percent evaporation from the A-class pan. The impact of Irrigation method on and the specific gravity of tubers and starch (dry matter) were and was not significant, respectively.
