A study on culms and above-ground biomass productivity based on threeharvesting techniques of Gigantochloa scortechinii (buluh semantan) in natural standshad been conducted in Betau, Pahang. After 18 months of observation it wasfound that the harvesting techniques gave highly significant effects at 0.05% bothon new culms and above-ground biomass productivity, whereas the effect ofclump density was highly significant at 0.05% in new culms production only. Basedon the study results, X-shape harvesting technique is recommended to be applied in the natural stands of bamboo. This method produced a higher number of newculms per clump and total above-ground biomass increment with the productionof 7.6 kg and 86.7 kg, respectively, as compared with Horse-shoe shape harvestingtechnique. Furthermore, it is recommended that only bamboo clump density withthe minimum number of 26 culms/clump were suitable for the application of thisharvesting technique. The clear-felling method is not recommended for theharvesting of the natural stands of Gigantochloa scortechinii due to the slow recovery.
