A factorial layout based on a randomized complete block design in three repetitions was carried out to evaluate and compare the effect of early and common planting on two potato cultivars in 2018-2019 in research farms at Razi University of Kermanshah. Experimental factors included 4 planting dates (November 16, 2018- March 16, 2019- April 9, 2019- May 10, 2019) and two cultivars (Sante and Marfona). Cultivar factor affected significantly on total yield, No. of small (less than 35 mm) and medium tubers, the weight of small and medium tubers (p< 0.01), marketable yield, and tuber dry matter (p<0.05). Also there were significantly different in total yield, marketable yield, the weight of medium and large tubers, number of large tubers, the weight of infected tubers, number and length of the main stem, dry matter percentage, and tuber starch percentage between various planting dates. The highest and the lowest mean marketable tuber yield were observed in November and May planting dates respectively 53.1 and 36.6 tonnes per hectare, respectively. Planting date also affected on infected tuber weight (p<0.01) significantly, so November planting date resulted in without infected tuber compared to other planting dates. Water consumption (m3.h-1) was 5040, 7230, and 6962in March, April, and May planting dates respectively were more than the November planting date (4350). Then net income increased 55% from the sale of tubers by shifting the planting date from common to autumn cultivation
