Abstract
Vermicomposting, a process leveraging earthworms' bio-conversion capabilities, transforms organic waste into nutrient-dense compost. The resultant vermicompost exhibits a peat-like structure, characterized by excellent moisture retention and nutrient availability, rendering it a valuable amendment for potting media. Application of vermicompost has been shown to significantly enhance mulberry plant growth and development, manifesting in increased shoot length, leaf count, fresh and dry weight of shoots, rooting percentage, and moisture retention capacity. Furthermore, vermicompost incorporation improves biochemical parameters, including total carbohydrates, proteins, crude fiber, and ash content, as well as major nutrient (N, P, K) concentrations. Notably, a higher proportion of vermicompost in planting media correlates with improved root growth, survival percentage, and root biomass. The enhanced nutrient profile and structural properties of vermicompost contribute to improved mulberry plant growth and yield parameters. These findings suggest that vermicompost can be a valuable tool for optimizing mulberry cultivation, particularly in soilless or containerized production systems. By harnessing the benefits of vermicompost, growers can potentially improve crop yields, reduce environmental impacts, and promote sustainable agricultural practices.
