  Three levels of nitrogen (0, 225 and 300 kg N ha-1) and 4 levels of potassium (0, 125, 175 and 225 kg K ha-1) fertilizers were applied to potato mother plants (MF-II) for the production of high quality True Potato Seed (TPS). The effect of N and K application on the quality of TPS was evaluated by nutritional analysis, germination tests in Petri dishes and growth performance in nursery beds. Increase in N application significantly increased N, P, Ca, Mg and Na concentrations in TPS but K did not increase. Increase in K application significantly increased N, P and K concentrations, while decreases in Ca, Mg and Na concentrations in TPS were recorded. TPS that were harvested under different NxK combinations were classified into large-(>1.18 mm) and small sizes-(1.18 to 1.00 mm). Among them, large TPS showed the highest germination rate (97.7%) 12 days after sowing when 300 kg N and 125 kg K ha-1 was applied. The coefficient of velocity of germination in large TPS was highest (10.4) when 300 kg N and 125 kg K ha-1 were applied. Large TPS also showed high emergence rate (94%), seedling vigor (4.8) and dry matter content (10.5%) in nursery beds when 300 kg N and 125 kg K ha-1 was applied. Large TPS always showed better performance than small TPS. In conclusion, the combination of 300 kg N and 125 kg K ha-1 was the best combination for application to potato mother plants for the production of high quality TPS.
