In order to investigate of the effects of different levels of drip irrigation and different cultivation pattern on yield and yield components of potato a split plot experiment based on the randomized complete block design with three replications was carried out at Allarog Research Station of Ardebil Province in 2004. Investigated factors included: Different levels of drip irrigation of 60, 80 and 100 percent of evapotranspiration of potato plant as the main plot. Cultivation pattern of the field were: (a) 1 row 75 cm on bed 75 cm (furrow to furrow), (b) 2 rows 35 cm on bed 150 cm (furrow to furrow) and 2rows 45 cm on bed 150 cm (furrow to furrow). It was found that increased irrigation resulted in higher fresh and dry yield of tuber per plant, mean fresh weight of tuber and number of tubers per plant. No significant difference was found in the number of tuber per plant between the treatment of providing 100% and 80% of water requirements. Different irrigation levels also affected the number and fresh weight of marketable tubers, maximum tuber number and tuber weight was obtained at the treatment of providing 100% water requirement. It was concluded that the yield of potato was strongly affected by water stress and there was no significant difference in yield among different cultivation patters.
