Abstract
Vermicomposting is the bio-oxidation and stabilization of organic
matter involving the action of earthworm and microorganism, turning waste into
a valuable soil amendment called vermicompost. Vermicomposting is an
ecofriendly process that converts organic substrates into value added
vermicompost with the help of earthworms and microflora. In this study, the
sugar industrial byproduct, sugarcane bagasse was vermicomposted in combination
with cow dung (1:1) in addition to the green manure plant Gliricidia sepium
as amendment material employing the earthworm, Eudrilus eugeniae. Prior
to vermicomposting, the substrate combinations were predecomposed for 15 days
by inoculating Pleurotus sajor-caju spawn. Results showed that pH and
electrical conductivity declined from the initial stage, total Kjeldahl
nitrogen, sodium, total phosphorus, total potassium, magnesium, calcium, zinc,
copper and iron levels were highly increased. Based on the present study
findings, it is recommended that the sugarcane bagasse+cow dung combination
amended with the green manure plant, G. sepium in 2:1:1 ratio is suitable
for producing nutrient rich vermicomposting utilizing the epigeic earthworm, E.
eugeniae.
