Effect of nitrogen rate with and without change of phosphorus and potassium rate was investigated in a field experiment. Percentage of plant mortality after transplanting increased with N rate above 32.5 kg/10a. The content of total nitrogen increased and potassium decreased slightly as the applied N was increased, but the contents of total alkaloid and phosphorus were not affected at each growing sta1676ge. It was considered that the application of 17.5 kg of P2O5 and 35.0kg of K2O per 10a might be sufficient for high yield and good quality. As the N rates increased, the yield, value, contents of total alkaloid and total nitrogen of cured leaf incre
