The comparison of bedding material ratio for feeding Eudrilus eugeniae was studied. The experiment was designed with Complete Randomized Design (CRD) consisted of 4 treatments as follow: 1) control (cow dung: coconut husk (2:1 w/w), 2) cow dung: kale (2:1 w/w), 3) cow dung: coconut husk: kale (2: 0.5: 0.5 w/w) and 4) cow dung: coconut husk: kale (2:1:0.5 w/w). The experiment was operated for 50 days and the results indicated that treatment 3 gave the highest total nitrogen, phosphorus, potassium and pH at 2.31%, 0.89%, 1.50% and 6.55% (P < 0.05), respectively. Treatment 2 gave the highest percentage of organic carbon (OC), organic matter (OM) and C:N ratio at 28.67%, 49.32%, and 17%, respectively. Meanwhile, treatment 4 showed the highest electrical conductivity (EC) at 4.95 (dS/m) (P < 0.05). From all of the results, it was clearly that vermicompost produced from this study provided the better quality of fertilizer than the organic fertilizer standard. However, treatment 1 gave the higher vermicompost yield than other groups (P < 0.05).
