The present experiment is to study the effect of N.P.K. fertilizers on the yield and quality of Angelica. Angelica acutiloba Kitagawa f. acutilioba Hikino was used as the material which was planted on the field under nine treatments.
1. The highest root yield was obtained in the treatment of N2 P1 K0 This indicated that the yield increased was primarily due to the increased application of nitrogen fertilizer. Less influence of potassium to the root yield was noticed.
2. No statically signigicant differences in the root yield among other treatment were found. However, The lowest rot yield in the N0 P2 K2 treatment was noticed, indicating that the yield decrease was due to lack of nitrogen fertilizer. Effect of potassium on the root yield seems to be not prominent, the larger effect of phosphorus on the root yield was noticed however.
