This study was intended to find out the effect of the fertilizer applications on the changes of the morphology, yield and effective components -Paeonol, Benzoic acid, Oxypaeoniflorin, Albiflorin and Paeoniflorin- of Paeonia albiflora Palls. The treatments of the field experiment were designed as follows ; conventional fertilization(R), organic fertilization(OF), chemcial fertiliazation(CF), combination of organic and chemical fertilization(OCF), and 50% and 100% increase of the chemcial fertilizers in combination treatments (OCF-50, OCF-100). The results obtained were summarized as follows ; 1. Depending on the treatments, the changes of the growth characteristics of the aboveground part were not significant, but the yield of the root had a significance on OCF-100. 2. The large quantities of effective components in Paeonia albiflora Palls were increased from the first year to the second year. 3. The excess phosphate application in the conventional fertilization affected to decrease the root yield and the effective components in its root. 4. The organic fertilizer was more favorable to the yield and the contents of the effective components of Paeonia albiflora Palls than the chemical fertilizer. OCF-50 and OCF-100 had higher values of yield and the amounts of the effective components than the treatments of the organic fertilizers.
