In order to determine the effect of mulch on some characteristics of potato, a factorial experiment based on randomized complete block design with three replications was conducted in Asadabad, Hamedan (Iran). The experimental treatments consisted of mulch in five levels (clear mulch, white mulch, black mulch, double layer mulch and control, without mulch) and cultivar in two levels (Agria and Sante). The effect of mulch on the fresh and dry weight of weed was significant, so that the black and double layer mulches had greatest impact on reducing the fresh and dry weight of weed, respectively. As compared to control, clear mulch treatments could reduce the period of tuber formation by 6.33 days. Double layer mulches showed the highest number of stolons at 60-day after planting. In comparison to the control, mulch could reduce the days to harvest, while the clear (104.83 days), double layer (105 days), and white (105.16 days) mulches all had significant differences when compared to the control (108.16 days). Cultivar Sante and double layer mulch also had the greatest impact on early potato crop. Mulch was not, however, seen to have significant effect on yield per plant. Based on the overall results, cultivar Sante and double layer mulch are suggested for the purpose of further study in Asadabad, Hamedan.
