Vermicomposting is an effective method for recycling organic wastes for the generation of vermicompost. In the present study fungal based pre-decomposed plant wastes were mixed with cow dung and green manure plant (Gliricidia sepium) were subjected to vermicomposting using African earthworm, Eudrilus eugeniae along with worm uninoculated control experiments under controlled conditions. The initial and final substrate mixtures were analyzed for pH, electrical conductivity, total organic carbon, total nitrogen, total phosphorus, total potassium, and C/N ratio. Besides, the initial and final substrates were tested for phytotoxicity with maize and cowpea to assess the suitability of the vermicompost for utilizing as organic manure. The results revealed a reduction pH, organic carbon and C/N ratio while increment in total NPK contents in the vermicompost than the control experiments without earthworms. The study suggests that the addition of cow dung and green manure plants in pre-decomposed plant biomass waste in 1:1:1 ratio is suitable for vermicompost production using the earthworm Eudrilus eugeniae.
