Abstract

To determine the effects of pre-germinating of tubers and plant density on yield and some agronomic traits of six commercial potato cultivars, an experiment was carried out in Ardebil Agricultural Research Station for two years (2001 and 2002). The experiment was in a split split splot on the basis of completely randomized block design with three replications. Pre-germination and non pre-germination treatments were used as the main plot, six potato cultivars Mondial, Draga, Agria, Arinda, Moren and Marfona as sub plots and plant densities of 75 ´ 25 and 75 ´ 20 cm as sub sub plots. The results showed that pre-germination significantly influenced tuber yield, number of tubers per plant, number of main stems and mean weight of single tubers. Cultivar Mondial with 35.688 tha-1 in pre-germination and 75 ´ 20 cm treatments produced the highest yield
