Vermicomposting is a way to turn organic waste into fertilizer. In this study, researchers used earthworms to turn banana pseudostem scutchers and cow dung into vermicompost. They tested different mixtures and found that a mix of 75% banana pseudostem scutcher and 25% cow dung had the best results. The vermicompost had more nutrients and was good for plant growth. It also didn't have any harmful effects on plants. This shows that banana pseudostem scutchers and cow dung can be used to make nutrient-rich fertilizer with the help of earthworms.
