Abstract: Vermicomposting appears to be simple, effective and eco-friendly method of organic waste management with lot of promise for organic farming and sustainable development. In most of the vermicomposting units only cattle dung and some agricultural wastes are used and no attention is being paid to include other organic waste stuffs which also pollute the environment and pose human health hazards. In the present study an attempt has been made to explore the possibility of bioconversion of mentha waste (MW) and rise husk waste (RHW) using Nigerian earthworm, Eudrilus eugeniae. In present experiment, three substrates were mixed in different combinations so as prepare 19 culture media in plastic containers and 30 adult earthworms were released. Culture was maintained for 45 days followed by observations. All combinations of rise husk waste and dung, dung alone and mixture of rise husk waste + mentha waste + dung (1:1:1) were found to be highly suitable and rise husk waste alone was moderately suitable. All other combination using mentha waste mixed with dung or rise husk waste were either little suitable or unsuitable for vermicomposting by E. eugeniae. It can be concluded that rise husk waste and mentha waste need to be mixed with cattle dung in suitable proportion for their successful recycling through vermicomposting.
