Bagasse at different concentrations 100, 200, 400, 600 and 800 g/kg, were subjected to composting for first 60 days and subsequently vermicomposted for 60 days. The experiment was terminated on 120th day. Earthworm species chosen for the present study were E. eugeniae, P. excavatus and E. fetida. Earthworm was harvested and their weights and net reproductive rate (nrr) were evaluated. Compost and vermicomposted SIW were physicochemically analyzed. No significant change in body weight of the earthworms was observed between the treated and untreated ones. Nrr of all the three species of earthworm were not affected on exposure SIW. Macro and micronutrients elevated both composted and vermicomposted of SIW. Further, heavy metals like Cr, Pb and Hg declined after composting and vermicomposting of SIW. This study demonstrates that vermicomposting technology could be an alternate strategy to convert the SIW bagasse into an agro beneficial product.
