Clonal forestry of teak in the community forest could increase the forest productivity where the shoot cutting was one of the vegetative propagation methods to propagate and maintain the superior clone of teak. However, the major problem on the shoot cutting of teak was the difference in rooting ability among rooting media, IBA (Indolebutyric Acid) and selected superior of teak clone. The research was conducted on split-split plot design with 10 individual as replication on each treatment. The main plot was two rooting media (cocopeat:rice husk 2:1/A; and soil:sand:compost 3:2:1/B). The subplot was IBA hormone concentration (0 ppm, 50 ppm, 100 ppm, 150 ppm) and the sub-sub plot was 11 clones of teak. The result showed that the rooting ability of teak was affected by all of treatments and interaction among them (P < 0.05), except for the interaction between IBA dosage and clone (P >0.05). The primary and secondary root length showed that clone and interaction between media and clone were significantly different (P < 0.05), while the media was only significantly different for secondary root length (P < 0.05). However, the number of primary and secondary root was not affected by the treatments (P>0.05). Moreover, the best result of rooting ability of teak for rooting media, IBA and was the cocopeat:rice husk (70,53%), IBA 150 ppm (53.18%) and clone WG2 (85%), respectively. It suggested that the seedling production of superior teak through the shoot cutting method depended on the rooting media, IBA concentration, and the specific of teak clone.
