THE EFFECT OF BAMBOO CLUMP MAINTENANCE ON NEW CULM PRODUCTION IN PENGLIPURAN BAMBOO FOREST BALI, INDONESIA

The use of bamboo in the daily lives of Balinese people requires sustainable access to good quality of raw materials. One way of doing that is by managing bamboo grooves. The aim of this study is to know the effect of bamboo groove maintenance on the productivity of bamboo culms in a bamboo forest at Penglipuran, Bali. The study was conducted by cutting >2years old culms and putting more soil around the bamboo groove. The difference in culms growth before and after treatments was calculated using analysis of variance that was followed by Tukey’s Test. The results showed that clump maintenance on bambu aya (Gigantochloa aya Widjaja & Astuti), bambu tali (Gigantochloa apus (Schult.) Kurz) and bambu papah (Gigantochloa sp.) generated an increase in the production of new culms. The number of culms of bambu aya increased by 150.5%, bambu tali 94.7% and bambu papah 150.6%.
