Coconut leaf vermiwash (CLV) was produced from actively vermicomposting coconut leaf litter + cow dung substrate (10 : 1 w/w basis) by Eudrilus sp. It significantly increased the seedling vigour index of cowpea and paddy at 1 : 10 and 1 : 15 dilutions in laboratory trials. Field trials carried out in red sandy loam soil (Arenic Paleustults) resulted an increase of 36% fresh biomass weight of cowpea with application of CLV at 1 : 10 dilution. In maize, increase in cob yield by 5
