Abstract

Castanopsis buruana Miq. from the Fagaceae family is one of the endemic species that grows in the lowland forests of Sulawesi. This plant has important economic value as a producer of wood and nuts which have high nutritional value so that they are suitable for cultivation. To support the development of the plantation forest C. buruana Miq. in Sulawesi, it is necessary to understand the silvicultural technique. Recently, C. buruana Miq. can be propagated by seed, but the problem is that it does not produced fruit every year, the seeds are easily damaged and have a hard and thick seed coat that takes a long time to germinate. Therefore, we need an alternative cultivation technology with vegetative propagation. This study aims to examine the success of growing natural seedlings of C. buruana Miq. at different media treatments and seedlings heights. This research was prepared based on a completely randomized design consisting of two factors. The first factor consisted of 3 levels of treatments, namely soil, soil + compost 1:1, and soil + compost 2:1. The second factor was the height of the tillers consisted of 3 levels of treatment, namely 10 cm, 20 and 30 cm. The data from the observations were analyzed using the F test, if the treatment had a significant effect then it was followed by the Duncan test with the 5% confidence level. The results showed that the type of media had no significant effect on all tested variables. The treatment of tiller height and its interaction had no significant effect on all tested variables, except for shoot height had a significant effect. Soil treatment + compost 1:1 yielded a live percentage and 100% sprouting percentage with a shoot height of 15 cm and a shoot dry weight of 0.67 g. The treatment of seedling height resulted in a live percentage and 100% sprouting percentage with a shoot height of 3 cm and a dry weight of 0.60 g. The composition of 1:1 compost soil media and 20 cm root height is the best treatment because it can incre
