Abstract:
This study reports the results of vermicomposting with Eisenia fetida of Parthenium hysterophorus mixed with cow dung in different ratios (25%, 50% and 75%) in a 18 weeks experiment. In all the treatments, a decrease in pH, OC(total) and C:N ratio, but increase in EC, N(total), P(aval), Ca(total), K(total) and heavy metals was recorded. The cocoons production and growth rate (biomass gain worm(-1) day(-1)) were maximum in 100% cow dung. The results indicated that parthenium can be a raw material for vermicomposting if mix with cow dung in appropriate quantity.
