Potato (Solanum tuberosum L.) ranks 6th position in terms of total cultivated area, 4th position in terms of production and 1st position in terms of productivity. Increased production and productivity of potato may create local employment and market for agribusiness promotion and help in poverty reduction. This field investigation was carried out during winter season of 2007/08 in the upland of Horticulture Farm of Institute of the Agriculture and Animal Science, Rampur, Chitwan, Nepal to evaluate the effect of seedling tuber size and level of potash on ware potato production of a clonal progeny of hybrid TPS, HPS II/67 so as to increased production and productivity with low cost of production. Growth parameters like plant height, number of stem per hill, stem diameter, number of leaves per plant were found to be influenced significantly due to variation in seedling tuber size and level of potash. The treatment combination (10-15 g seedling tuber size and 120 kg K2O/ha) was found most effective and gave the highest yield of (30.03 mt/ha).
