A study on culms and above-ground biomass productivity based on three harvesting techniques of Gigantochloa scortechinii (buluh semantan) in natural stands had been conducted in Betau, Pahang. After 18 months of observation it was found that the harvesting techniques gave highly significant effects at 0.05% both on new culms and above-ground biomass productivity, whereas the effect ofclump density was highly significant at 0.05% in new culms production only. Based on 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 new culms per clump and total above-ground biomass increment with the production of 7.6 kg and 86.7 kg, respectively, as compared with Horse-shoe shape harvesting technique. Furthermore, it is recommended that only bamboo clump density with the minimum number of 26 culms/clump were suitable for the application of this harvesting technique. The clear-felling method is not recommended for the harvesting of the natural stands of Gigantochloa scortechinii due to the slow recovery.
