Abstract
The present study reveals that the efficacy of the mono and polyculture species of earthworms on the aspects of microbial population in the different compost such as clay loam soil, cow dung, farmyard manure and vegetable debris. It is observed that the efficacy is noteworthy with the polyculture species. There must be coordination among the species perhaps there is a everlasting phenomenon of competent feeding of organic compost. The total microbial population shows that a high level of microbes in the freshly laid casts of all the samples. The microbial population is every time reduced in the 45 days old samples of all kind. Especially in the polyculture composts, the total microbical population is reduced considerably than monoculture and shows that the worm casts having a potential antimicrobial activity.
