Abstract:
Epigeic earthworms have the ability to convert organic wastes into valuable vermicompost as biofertilizer for and worm biomass as animal feed. The present work was undertaken to find out the quality of produced compost (without worm) and vermicompost (with Eudrilus eugeniae) out of different organic wastes [Cattle manure (CM)-Control, Eupatorium odaratum (EO), Tectona grandis (TG), Lantina camera (LC), Mangifera indica (MI), Cassia fistula (CF)] through their physico-chemical analysis such as pH, EC, % Organic carbon, available macro(N,P,K,S,Ca,Mg) and micro nutrients(Fe,Cu,Mn,Zn) were estimated through standard methods. Results revealed that % Organic carbon (OC) was more in compost compared to vermicompost whereas remaining parameters such as pH, EC, macro and micro nutrients were almost more in vermicompost than that of compost in all organic wastes. Again the quality of compost and vermicompost mainly depends on the nature of waste, potentiality of the earthworm in vermicomposting process, the activities of saprophytic microorganisms present in the earthworm gut and prevailing environmental conditions. The vermicompost produced by the earthworm, Eudrilus eugeniae from different organic wastes have all the essential physico-chemical parameters as biofertlizer for sustainable agriculture practices.
