In oder To determine the relationship between planting depth and potato seed tuber yield and yield components of two cultivars Agria and Draga response curves to the factorial experiment with two factors, factor in sowing depth first Tuesday (10, 15 and 20 cm)and the second factor of two cultivars (Agria and Draga) in a randomized complete block design with three blocks in 2007-2008 Farming Village Meadows Farvj city functions performed in the East North Khorasan Province and Attributes such as number of stems per plant, number of tubers per plant, average tuber weight, tuber yield and total number of eyes was determined, Depth of planting Traits, the number of stems per plant, number of tubers per plant, average tuber weight, tuber number and yield levels in the eyes of a percentage difference between the mean And the highest overall performance of the three planting depth, planting 10 cm were producedIncreasing the planting depth of 10 cm total decreased performance.Regression showed that the relationship between planting depth with the total number of tubers per plant and tuber number in both the linear and quadratic models significantly. But the number of stems per plant yield, average tuber weight, the likelihood of a significant level only in the linear model.Relation to planting depth on potatoes as a function of the curve And the slope of the line is That for every centimeter increase in planting depth reduced the rate of 1183 kg. The highest positive correlation between the number of stems per plant, number of tubers per plant (r=0.85**) correlation between the total number of tubers per plant (r=0.67*) and a negative correlation between the mean tuber weight the number of tubers per plant (r=0.60*) was shown. So in the production of seed tubers the number should be given to attribute of stems per plant It also increases the number of stem tuber number will increase. Seed production is important because of the weight of the thyroid gland, it is suggested that in modify this attribute is given.
