DEGRADATION OF COIR WASTE AND TAPIOCA PEEL BY EARTHWORMS

Abstract

                                Degradation of coirwaste and tapioca peel by earthworms with and without feed was tried under laboratory condition. The rate of degradation was maximum in treatments with earthworms that received cowdung as feed. Degradation was marked by the decrease in organic carbon content, C/N ratio and the subsequent increase in major and minor nutrient contents and microbial activity in both coirwaste and tapioca peel. The hydrogen cyanide (HCN) content in tapioca peel also got reduced to an appreciable level.

Key words : Coirwaste, Tapioca Peel, Earthworm, Degradation, Nutrients
