Abstract Lac is the most predominant source of natural resin and dye used for varied applications. Lac is secreted by tiny coccid insect Kerria lacca. India has its monopoly in production of lac and Jharkhand contributes to 60% of total lac produced in the country. The conventional host plants for lac production are Butea monosperma (Palash), Schleichera oleosa (Kusum ) and Zizyphus mauritiana (Ber). Other host trees Acacia spps., Albizia spps., Ficus spps., grow abundantly in Jharkhand. Out of the two lac strains Rangeeni & Kusmi, quality of Kusmi lac is superior and in great demand. Traditionally Kusmi lac cultivation is done on Schleichera oleosa (Kusum) as summer crop & on Zizyphus mauritiana (Ber) and Flemingia semialata as winter crop. As lac cultivation on F. semialata is expanding to wider areas of Jharkhand, the demand for Kusmi broodlac for inoculating newly sown semialata plants is rising. The above experiment was undertaken to asses and achieves sustainable Broodlac production during summer on F. semialata in Acacia auriculiformis (Akashi) plantation for two consecutive seasons at a village farm in Angara Block of Ranchi district. The Broodlac yield on semialata plant was encouraging especially on those plants growing in shade of Akashi plantation. Semialata plants near (plants in 3m. radius proximity of Akashi trees) and far from Akashi trees (plants located beyond 3m. radius but between Akashi trees) recorded 352.54g/plant and 299.18g/plant higher average Broodlac yield respectively over Control (plants located in open area) which was 207.21g/plant. Broodlac yield recorded during summer season under A. auriculiformis plantation was lower than Broodlac yield potential (500-1000g/plant) of normal winter season crop of F. semialata. Nonetheless, the result of experiment for taking up lac cultivation on semialata under Akashi plantation during summer months is encouraging for sustainable broodlac cultivation as broodlac is an essential component for propagation of next lac crop. This will maintain crop cycle and sustainable lac cultivation.
