Abstract: Growth rate of epigeic earthworm Perionyx excavatus was recorded in the decomposing leaf litter of five tree species, namely Acacia auriculiformis, Shorea robusta, Anacardium occidentale, Eucalyptus citridora, mangifera indica under laboratory conditions on 15th, 30th and 45th day. Biomass of earthworms increased significantly from the initial value in all the leaf litters tested but maximum weight gain indicating highest growth rate was observed in the litter of Anacardium occidentale (cashew) (4.15 ± 0.12 mg/worm/day) and minimum growth rate was observed in the litter of Eucalyptus citridora (eucalyptus) (2.92 ± 0.03 mg/worm/day) in 45 days. The digestive enzymes, i.e., α amylase and cellulase activities of P. excavatus were comparatively higher in Anacardium occidentale in comparison to Eucalyptus citridora during the experiment indicating the higher palatability of Anacardium sp (cashew) for P. excavatus.
