The objective of this study was to evaluate the effects of the application of vermicomposts on the growth parameters and ginsenoside content of ginseng roots. Food waste vermicompost (FW), cow manure vermicompost (CM), and paper sludge vermicompost (PS) were applied at 10 and 40 t ha , respectively. One-year-old seedlings were transplanted and 4-year-old roots were harvested. Soil nitrate and phosphate concentrations were increased in the plots applied with FW and CM at 40 t ha -1. Soil pH and exchangeable Ca concentrations were higher at FW 40 t ha -1 than at CM 40 t ha Effects of vermicomposts on root yield (a), rate of survived root and root rot disease (b). Con, control; FW, food waste vermicompost; CM, cow manure vermicompost; PS, paper sludge vermicompost. Means of each parameter with different letters are significantly different at P < 0.05 according to Duncan's multiple range test.
