This study was conducted to investigate the proper fertilizer application level and top-dressing method of Lycium chinense MILL in 1984 and 1985. The results obtained were summerized as follows; Stem length was 4cm longer, leaf area was 45-490$ extrm{cm}^2$ larger, dry matter weight per plant was 1.6-5g heavier and average yield of dry fruit of two years was higher as 183kg per l0a in double amount of potassium( 14kg/l0a) application than in standard level of potassium(7kg/l0a). Highly positive correlation was found between absorption amount of inorganic elements of phosporus(l%), nitrogen, potassium(5%) and dry matter weight. Proper fertilizer application level was 13.8kg(N), 14.2kg(P) and 14.3kg(K) per l0a. Dry fruit yield of top-dress-ing plot was 20% heigher than that of basal dressing plot through increase of leaf area per plant and dry matter weight per plant.
