Earthworms are beneficial fana residing under soil and play a vital role to improve soil health which ultimately enhance the yield of produce.in the present studies population density of earthworm were observed in datepalm and mango orchards. Total 192 sampling sites (96 under the canopy and 96 away from the canopy) were selected for study. From these sampling sites, 12 sampling sites (6 for Mango and 6 for Date palm fields) were selected randomly by the replacement sampling method every week. From Mango field 90 (under the canopy 48 and away from the canopy 42) while in Date palm field 55 (under the canopy 30 and away from the canopy 25) specimens were collected.
