Seasonal variations in compostability and production of vermiprotein by Eisenia fetida.

ABSTRACT

The potential of E. fetida to degrade wastes into vermicompost and to produce vermiprotein in the form of worm-biomass during different seasons was evaluated. Results revealed that the environmental factors prevailing during different seasons did influence directly the life activities of the worm and indirectly the compostability of the wastes. Feeding activities of E. fetida reduced the time of production of an efficient organic pool with energy reserves as vermicompost. Further, the amount of vermicompost produced by the worm activity depended primarily on the environmental factors and secondarily on the nature of organic wastes.
