Influence of N P and K fertilizers on seed yield and seed quality of bitter gourd (Momordica charantia L.) were studied. Bitter gourd was grown and treated with the combination of 3 rates of nitrogen (0 15 and 30 kg N/rai), 3 rates of phosphorus (0 10 and 20 kg P2O5/rai) and 2 rates of potassium (0 and 10 kg K2O/rai) fertilizers. Factorial in randomized complete block design with 3 replications was used. The results showed that N, P and K fertilizers had no significant effects on the first bloom of male and female flower (earlines), total number of fruits, weight per fruit, number of seeds per 7 square m (6 plants), number of seeds per fruit, total seed weight and 100 seeds weight. However, the high rates of N, P, and K gave highest germination (92.9 percent) and germination index (23.2) were combination of 30, 20 and 10 kg N, P2O5, and K2O/rai respectively.
