To investigate the effects of soil depth and time of applying the soil (soiling time) of the plant foot, an experiment in a randomized complete block design at the research station of Islamic Azad University of Ardabil was conducted. The factors were the time of applying the soil of plant foot (bush height 15, 25 and 35 cm) and depth  of applying the soil in this pattern (or soil forming) (bush height 1/2, 1/3 and 2/3). According to the results, by applying the soil (or soiling) in the height of 25 cm and 1/2 of the plant height, the highest yield was shown. As a result, the most number of stems per area unit and the most glands per area unit were obtained in this height of plant and depth of soil near the foot of bush.


Key words: Ardabil, planting depth, potatoes, soiling time, yield.
