Vermicomposting of Eicchornia, Ipomea and Parthenium using Different Species of Earthworm

This study has been undertaken to compared the nurient levels of vermicompost by used different substrate such as cow dung, Eichhornia crassipes, Ipomoea carnea and Parthenium hysterophorus weeds by the efficacy of the two earthworm species Eisenia fetida and Eudrilus eugeniae were tested. The physical, chemical, biological factors of these obtained vermicompost were determined. Then the effect of these vermicompost in the growth of Vigna radiatae carried out. Among the study Eisenia fetida showed highest nutrient value of vermicompost than Eudrilus eugeniae. The cow dung vermicomposts (A1 and N1) showed highest nutrient value and growth parameters of Vigna radiatae followed by combined source of cowdung and weed vermicompost (A5, N5, A3, N3, A7 and N7) than weed vermicompost without cowdung (A5, N5, A3, N3, A6 and N6).
