The present study had an objective to optimize important parameters viz., incubation period, pH and moisture per cent for vermicomposting of biomethanation sludge admixed with fruits and vegetable waste collected from Gultekadi Market Yard, Pune using Eudrilus eugeniae. The experiment was conducted on the terrace of H.V. Desai College of Arts, Commerce and Science, Pune. The sludge from biomethanation digester running on fruits and vegetable waste was collected and dewatered. The fruits and vegetable waste was collected from Gultekadi Market Yard, Pune and used for the experiment by processing it. The dewatered sludge was admixed with partially decomposed fruits and vegetable waste. The 1kg working capacity plastic trays were used for the optimization of parameters. It was found that incubation period of six weeks, pH 7.0 and moisture content of 70-80% were the optimum condition for Eudrilus eugeniae vermicomposting. The average growth rate mg/worm/day for the optimized incubation period, pH and moisture % was 4.4±0.14, 5.57±0.1 and 7.5±0.47, respectively and at all the three optimized conditions was 7.8±0.6.
