Effects of showing rate on the mortality of Eisenia fetida in different substrates

Vermicompost is the best and easy remedy for solid waste management. Naturally earthworms play a major role in recycling of wastes. The present research work, attempts to study the mortality of Eisenia fetida reared in different substrates. The epigeic earthworm Eisenia fetida were selected for the present study. The Eisenia fetida was bought from agricultural farm at virudhunagar. The control was filled with either pure cow manure or goat manure or pig manure. The proper moisture content was maintained throughout the experiment. After 15 days, 5 non-clitellate earthworms Eisenia fetida (200 to 250 mg) were introduced into each rectangular tray. The triplicates for control and experimental samples were maintained throughout the research period. All trays with earthworms were kept in dark room. Mortality was recorded weekly for 6 weeks. No additional feed was added at any stage of the experiment
