The potential of two epigeic earthworms (Perionyx excavatus and Eisenia foetida) was studied for
composting of crop residues (wheat straw and paddy straw) amended with farm yard manure. At the end
of vermicomposting significant increase in total nitrogen (71 -150%), phosphorus (49 %–116%) and
potassium (26.3–142%), along with decrease in organic carbon was recorded in different experimental
vermibeds. Maximum total nitrogen as well as available phosphorous concentration was observed from
vermibeds inoculated with E. foetida, whereas increased exchangeable potassium and reduction in
organic carbon was shown in vermicompost produced by P. excavatus. Enhanced hydrolytic enzyme
activities of CMCases (1.51 folds), Fpases (2.11 folds) and β-glucosidases (1.38 folds) were recorded in
treatments vermicomposted with P. excavatus. Microbial activity parameters such as dehydrogenase,
FDA hydrolase, alkaline phophatase, were also monitored during decomposition process and gradual
increase was recorded in vermibeds up to 90 days of experimentation. The mean individual live weight,
growth rate (mg wt. worm
-1
day-1
) of earthworm were higher for P. excavatus as compared to E. foetida.
Overall, P. excavatus exhibited better growth and mineralization efficiency, which further support the
suitability of the species for large scale vermiculture operations.
