Background : This study was performed to know the effect of mulching materials on the growth and root characteristics of Platycodin grandiflorum Ridix. Methods and Results : Platycodin grandiflorum Ridix was treated by with biodegradable film, rice husks, and sawdust, non-mulching (hand weeding). To measure the fresh weight and length, thickness and the number of fine root of the Platycodin grandiflorum Ridix roots harvested in October. Root length appeared in the biodegradable film and sawdust were 27.5 and 26.7㎝ longest, rice husks was the shortest 22.0㎝. Diameter at the thickest showed 30.9 ㎜ in biodegradable film, the following phrase appeared sawdust and rice husks application. The number of fine-root was investigated in biodegradable film most piece 36.0. Fresh weight, which is directly related to yield were biodegradable film to 130 g the highest in the number of fine-root and the longest root length. Conclusion : For the increasing the yield that Pharmacological effect, biodegrada
