Vermicompost generated from animal dung is universally believed to be beneficial to soil and plants. In the present study, nutrient availability of the vermicompost was increased by mixing plant materials with biodigested slurry in equal proportions. Among the five plants used (water hyacinth, parthenium, neem, mulberry, Lantana camera) the organic carbon, NPK levels and bacterial population were higher with the neem compost followed by parthenium compost. As parthenium compost is also found to be good, the vermitechnology could be well adopted for parthenium eradication and to keep a clean environment. Thus vermicomposting, a novel technique of converting decomposable organic wastes into valuable compost.
