Eisenia fetida is a temperate epigeic earthworm commonly used for vermicomposting. A study was conducted to compare vermicomposting by Eisenia Fetida in four different organic wastes. The four media were kitchen waste, shredded banana trunk, shredded newspaper and cow manure. The chemical analysis such as total nitrogen (N), available phosphorus (P), potassium (K), calcium (Ca), magnesium (Mg), zinc (Zn), copper (Cu), sodium (Na), iron (Fe), manganese (Mn), nickel (Ni), aluminium (Al), lead (Pb), total organic carbon (C) and C:N ratio was also determine on the media before and after treatment with earthworms. Kitchen waste was found out to be the best media for vermicomposting followed by shredded banana trunk, shredded newspaper and cow manure i.e 20.35, 24, 29.9 and 38.05 (days/20g earthworms/300g media) respectively. Results showed significant increment in Total N, Available P, potassium (K), calcium (Ca), magnesium (Mg), zinc (Zn), copper (Cu), sodium (Na), iron (Fe) and aluminium (Al) in the vermicast compared to the raw media. The C:N ratio decreased significantly in all media after vermicomposting.
