Bridging the Gap: Agronomical Constraints and Extension Needs in Mulberry Farming - A Case Study

Abstract— Mulberry cultivation is essential for successful sericulture, as the quality of leaves directly impacts the growth of silkworms, cocoon yield and silk quality. However, various agronomic challenges such as poor soil fertility, waterlogging, improper nutrient management, pest and disease outbreaks, continuous cropping and inadequate residue handling can lead to reduced leaf quality and plant vigour. Improper practices like mulching of mulberry twigs, indiscriminate disposal of pruning residues, and neglect of pruning or canopy management further compound these issues. This case study documents these prevalent constraints through systematic field observation and interaction with sericulture farmers in Karnataka. Implementing sustainable practices such as soil testing, balanced fertilization, organic matter incorporation, moisture conservation, proper pruning, pollarding and residue management in a scientific manner can enhance leaf nutrient composition, improve photosynthetic efficiency, reduce pest and disease incidence, and boost overall productivity. Bridging the knowledge gap through extension services, training and field demonstrations is essential to promote these practices, ensuring high-quality mulberry leaf production, sustainable sericulture, and enhanced livelihoods for farmers.
