Vermicompost Production by Using Tomato Residue and Yard Waste

 Abstract—Tomato residue and yard waste were used as substrate for vermicompost production. These two organic wastes were suitable for feeding Eudrilus eugeniae. E. eugeniae was cultivated under four feeding conditions; control (no organic waste added), adding tomato residue, adding grass waste and adding tomato and grass. Vermicomposts from all conditions provided major nutrients (N, P, K) higher than the standard of organic fertilizer. All vermicomposts were applied to Chinese cabbage and zinnia. The results showed that all formula of vermicomposts supported crop plants as good as chemical fertilizer. Vermicomposts may benefits both economical and environmental purposes. Index Terms—waste reduction, tomato residue, yard waste, Vermicompost.
