Two field experiments were conducted on a private farm in Kafr El-Zayat, Gharbia Governorate, Egypt (latitude 30.867344' N and longitude 30.802303' E), during two successive summer seasons of 2020 and 2021 to investigate the effect of planting depth (10, 15, 20 and 25 cm) on vegetative growth, productivity and quality of potato tubers (Solanum tuberosum L.) cv. “Kingsman". The soil texture of the experiment site was clay loam. Generally, there were significant differences among the various treatments of planting depth, in both seasons. The highest significant were obtained at 10 cm planting depth for earliness of potato sprouts emergency, plant height, leaf area, number of leaves per plant, number of tubers per plant, weight of green tubers per fed and cracks of tuber per fed. Moreover, planting depth at 20 cm showed the highest significant value for the number of stems per plant, fresh weight of tubers per plant, size of tubers per plant, total yield and marketable yield per fed. While the lowest values for the same traits were revealed from planting depth at 25cm except marketable yield at 10 cm and tuber cracking at 20 cm in both seasons. However, there was no significant difference among treatments on length of stolons per plant and number of stolons per plant in both seasons. This study recommended that planting depth at 20 cm recorded the best values for most of treatments including lowest tuber greening and cracks.
