Banana crop waste biomass was successfully turned into nutrient-rich compost using earthworms in a process called vermicomposting. By mixing banana leaf waste with cow dung, the earthworms broke down the materials over 105 days, improving the compost's quality. The compost had lower acidity and higher nutrient levels compared to the initial waste. The best results were seen when the compost had 20-40% banana leaf waste. This study shows that vermicomposting can be a useful method for managing banana crop waste.
