Conserving broodlac on Flemingia semialata in Albizia procera (siris) plantation during summer season under rainfed condition

Abstract: Lac, due to its use in high valued diversified field and being bio-degradable in nature, has gain momentum in cultivation in recent times, accounting for about 50–60% of the total world lac production in India. Out of cultivation of two dominating lac strain (kusmi and rangeeni), focus of kusmi lac cultivation has remained on Schleichera oleosa (kusum) as summer crop and on Ziziphus mauritiana (ber) and Flemingia semialata as winter crop. However expanding plantation of F. semialata in newer non-conventional areas (area without alternate host) requires attention on sustainable broodlac production during summer on other conventional lac host. Present investigation was carried out to find out the performance of F. semialata planted in Albizia procera (siris) plantation for conserving broodlac during summer season at research farm of ICAR- Indian Institute of Natural Resins and Gums, Ranchi for two consecutive seasons. Semialata plants near (plants in the periphery of 3.0 m radius of siris tree) and far from siris tree (plants located in between siris trees but beyond 3.0 m radius of siris tree) recorded 84.8 and 60.9 per cent higher broodlac, 32.3 and 25.6 percent higher total lac yield with 20.9 and 18.4 per cent lower rejected lac yield over control (plants located in open environment), respectively. The mean broodlac yield per plant on F. semialata planted near and far from tree in siris plantation were 134.1 and 116.8 g/plant, respectively, with average yield of 125.4 g/plant. Broodlac yield recorded during summer season under siris plantation in the study was 58.2 per cent lower than broodlac yield potential (300 g/plant) of normal winter season crop on F. semialata, but it may be inoculated on 3-4 bush of semialata to raise winter crop. This will help to maintain crop cycle and thus sustainable lac cultivation. Higher broodlac and lesser rejected lac yield on semialata in siris plantation could probably be due to higher shoot length, weight of single cell, weight of broodlac per meter of shoot length and lesser weight of rejected lac per meter of shoot length. Hence, sustainable broodlac production on F. semialata may be taken under siris plantation during summer in newer areas, where suitable lac host species for summer lac cultivation (kusum) is not available.
