Abstract
NPK experiment with two year old Korean red pine tree seedlings produced in Kangwon Province has been conducted during four years from 1963 to 1966 through pot trial. In order to minimize experimental error, this experiment laid out 27 treatments with 8 replications. The result of this experiment revealed that responses to nitrogen and phosphorus fertilizers were distinct whilst its response to potassium fertilizer was negligible when seedlings were free from the needle cast infection. After needle cast disease was seriously infected, however the response to potassium was very outstanding and followed by phosphorus effect. The response to nitrogen was not able to be observed among the levels of nitrogen application. Therefore, it may be said that potassium application could produce healthy pine seedlings those which tolerant to the needle cast infection.
