An experiment was conducted on preparation of vermicompost with different farm wastes and weeds. All the vermicompost samples of different farm and weed wastes are neutral in reaction (7.15 to 7.35) which is congenial for release and utilization of nutrients by crops. The available potassium content in so prepared vermi compost was significantly increased over initial values of papaya leaf litter, glyricidia loppings and pigeon pea stalks. There was a tremendous increase of organic carbon content in vermicompost of farm and weed wastes. There was a very less weed infestation (2%) in the groundnut crop with the vermicompost prepared from the problematic weeds like celotia and parthenium. The available nitrogen, potassium and organic carbon content of the soil was increased significantly with the application of vermicompost from different farm and weed wastes.
