UTILIZATION OF SOME WEEDS AS SUBSTRATES FOR VERMICOMPOST PREPARATION USING AN EPIGEIC EARTHWORM, ELIDRILLIS ELIGENIAEN. KARMEGAM AND THILAGAVATHY DANIELAbstract Eudrilus eugeniae, an epigeic earthworm used for the decomposition of four kinds of locally available weeds, viz. Boerhavia diffusa, Pavonia odorata, Sida acuta and Trianthenia portulacastrum showed that all the four common weeds can effectively be used for the production of vermicompost of high quality based on the NPK values, increased rate of electrical conductivity, reduction of organic carbon and higher range of microbial colony forming units (bacteria, fungi and actinomycetes) in combination with cowdung in 1: 1 ratio by dry weight.
