Soil pH for mulberry cultivation generally ranges from 6.5 to 7.5, while non-mulberry host plants exhibit resilience in slightly acidic to neutral soils, enabling flexible sericulture practices across varied geographic regions.
Yield and Cocoon Quality Comparison
Mulberry plantations produce higher yield and superior cocoon quality compared to non-mulberry plantations, as the Bombyx mori silkworm thrives on the nutrient-rich mulberry leaves, resulting in larger, more uniform cocoons with higher silk filament strength. Non-mulberry plantations, such as castor or tapioca, typically yield lower quantities of cocoons with less consistent silk quality due to the varied nutritional profiles of alternative host plants. The choice of plantation directly impacts silk fiber length, tensile strength, and overall commercial viability in sericulture.
Economic Viability and Profitability
Mulberry plantations dominate sericulture due to their higher economic viability, yielding more nutritious leaves that enhance silkworm growth and silk quality, resulting in greater profitability per hectare. Non-mulberry plantations, such as castor or oak, offer diversity but generally produce lower silk yields and market value, limiting their economic returns. The intensive cultivation and faster crop cycles of mulberry plantations provide consistent revenue streams, making them the preferred choice for commercial silk producers.
Pest and Disease Management
Mulberry plantations, primarily used for rearing Bombyx mori silkworms, benefit from well-established pest and disease management protocols targeting common threats like leaf spot, powdery mildew, and mulberry silkworm grubs. In contrast, non-mulberry plantations, which support species like Antheraea and Samia, face diverse pest challenges from varying host plants, requiring tailored integrated pest management (IPM) approaches specific to each plant species. Effective pest control in both systems includes regular monitoring, biological control agents, and resistant plant varieties to reduce the impact of pests and diseases on silkworm health and sericulture yield.
Sustainability and Environmental Impact
Mulberry plantations for silkworm rearing promote sustainability by providing a renewable and high-yield source of food for Bombyx mori, enabling efficient silk production with minimal chemical inputs.
