Abstract

India produces around 3000 million tonnes of organic wastes annually. The disposal of ever increasing amount of organic wastes is becoming a serious problem in India. The hygienic disposal of organic wastes by composting is an environmentally sound and economically viable technology resulting in the production of organic fertilizer which is a basic and valuable input in organic farming. The waste collected from the market was grouped into vegetable waste, tapioca waste and sugarcane bagasse. The waste was subjected to initial decomposition under shadow. After that it was allowed for stabilization (24 h) in mud pots before inoculation with Eisenia foetida. Physico chemical analysis was performed on the 51st day. It is found that tapioca generates a rich vermicompost with an acidic pH, low electrical conductivity, high TKN%, phosphorus and potassium. This is followed by sugarcane bagasse with neutral pH, low electrical conductivity, high TKN % and low total organic carbon. Vegetable waste has high phosphorous and potassium and low total organic carbon.
