Abstract: Water hyacinth, sugarcane bagasse and rice husk are major bio-organic wastes causing severe environmental problems. For their biodegradation, Eisenia fetida was used as a vermicomposting worm in outdoor open field conditions. The above wastes were mixed separately with fresh cow dung in the ratio 1 : 5 (by weight). The mixtures were vermicomposted for 90 days in pits of size 2 × 0.5 × 0.6 m (l × b × d). The population and biomass of earthworms, and C:N ratios in the resultant vermicomposts were studied at the end of experiment.

Keywords: bio-remediation; vermicomposting; earthworms; Eisenia fetida; worm population; biomass; environment; water hyacinth; sugarcane bagasse; rice husk; biodegradation; solid waste management; bio-organic wastes.
