Abstract:
Mulberry leaves are vital for the silkworm, Bombyx mori, serving as their primary food source. The quality of these leaves significantly influences cocoon production. Factors such as variety, soil type, cultivation practices, diseases, and foliar sprays affect the biochemical composition of mulberry leaves. This study investigates the impact of the foliar formulation ‘Surya Kiran’ on the biochemical constituents of V-1 mulberry leaves, specifically focusing on soluble proteins and carbohydrates. Conducted in a controlled mulberry garden, treatments with ‘Surya Kiran’ were applied at varying concentrations (0.5% to 2.5%) alongside water and absolute controls. Leaf samples were analyzed for moisture content, chlorophyll levels, soluble proteins, and carbohydrates. Results indicated that moisture content was highest in the absolute control, while chlorophyll 'a' content peaked at the 2.0% concentration of ‘Surya Kiran’. Chlorophyll 'b' and total chlorophyll levels varied, with significant differences noted across treatments. This study highlights the potential of foliar applications to enhance the nutritional quality of mulberry leaves, which may contribute to improved silkworm productivity and, consequently, higher silk yield.
