Effect of Shoot Number, Diameter and Lac Encrustation Thickness on Kusmi Broodlac Yield of Kerria Lacca From Flemingia Semialata

This study aims to identify the significant factors affecting kusmi broodlac yield and the relationship between the broodlac yield and the relevant factors for providing the practical basis of maximizing this yield. The regression analysis between the yield and independent variables revealed that the major factors influencing yield include encrustation thickness followed by shoot diameter in a significantly positive relationship. The yield was increasing up to 12 shoots/ plant and started declining after this.
