Abstract: A pot experiment was conducted with an object to produce enriched vermin-compost with the use of different substrata and additives. Therefore twelve treatment combination consisted of two substrata of soybean stover and paddy straw and six additives (without additive, Trichoderma+ PSB, CD+ mixed to gather and left for partial decomposition for 21 days and subsequently, allowed for dization by earthworms. During the experiment observation with respect to change in PH, Temperature, dry weight of substrata as well as content of NPK were recorded up to 21 days. There after 200 gm worms to each treatment were released. Higher multiplication (2.31) and conversion rate of 186.31 g/day were recorded under T4 which was significantly superior over rest of the treatment combinations except T3 and T6. More over, it required a ttal of 59 days to complete the vermicompost process including partial decomposition of 21 days. Whereas, paddy straw without additive CD based amendments and inoculation with Trichoderma + PSB found beneficial with respect to growth and development of earthworms. The maximum weight gained by earthworms was 208 g under the treatment of T4 (Soybean stover+CD+Tricho+PSB). Higher content of N (2.10%), P (0.89%) and found to bevermicompost produced from soybean stover amended with CD as well as inoculation of Trichoderma+PSB
