In this study, corn sillage was converted to vermicompost and vermiwash through earthworm bio conversion. Eisenia Fetida earthworms loaded at a rate of 2.5 kg/m2 were used as the vermicomposting media over a period of 30 days in a vermireactor. The corn sillage vermiwash and vermicompost produced were analysed for bio fertilizer nutritional composition. The vermicompost had a nitrogen, phosphorous and potassium (NPK) composition of 0.52-1.53%, 0.18-1.06% and 0.13-0.74% respectively, whilst the vermiwash had an NPK composition of 0.011-1.83%, 0.003-1.65% and 0.062-1.73% respectively. Bio conversion of corn sillage to vermi- products presents an opportunity to boost food security and at the same time resource recovery from waste.
