Abstract:
Efforts were made to evaluate the impact of substrate materials (crop residues + sheep manure, cowshed manure, and kitchen waste + leaf litter) on growth and reproduction performance of composting earthworms: Eudrilus eugeniae, Perionyx excavatus and Perionyx sansibaricus, under laboratory conditions. Results indicated that earthworm biomass and cocoon production rate was directly related to the type of earthworm species as well as nature of worm feedstuff. Although cocoon hatchling success did not show any relation with type of culture material, but hatchlings numbers cocoon<SUP align=right>−1</SUP> was directly related with quality of substrate. This study suggests that earthworm production can be managed by using feedstuff having higher nitrogen contents with low C:N ratios.Keywords: ENVIRONMENTAL JOURNALS; Environment and Sustainable Development

- The objectives of International Journal of Environment and Waste Management are to establish an effective channel of communication between policy-makers, government agencies, academics and research institutions, and professionals working in the field, and to provide a forum for them to disseminate information. The international dimension is emphasised in order to overcome cultural and national barriers and to meet the needs of accelerating technological change and changes in the global economy. It will serve as a vehicle for the documentation and dissemination of what government bodies, research agencies, international bodies, universities, aid agencies, industries, and environmental scientists and professionals are doing in the areas of environmental and waste management.
