ABSTRACT
Octomeles sumatrana is a fast-growing indigenous commercial timber species commonly used in enrichment planting in Sabah. The high production corridor (HPC) is an extensive network of forest areas designated for restoration through enrichment planting to fill in forest gaps created during harvesting. The objectives of the paper to assess the early survival and growth performance of O. sumatrana in a spacing and fertiliser trial on a severely degraded forest site. The RCBD trial was established with three block replicates (spacing) and three plot replicates (fertiliser) was established. Six months after planting, the height, collar diameter and survival of seedlings were determined. The two-way ANOVA indicated that the mean height and collar diameter of O. sumatrana differed significantly by both spacing treatment (F(3)=18.73, p< 0.001), (F(3)=15.198, p< 0.001), respectively and by spacing x fertiliser treatments (F(6)= 3.19, p< 0.00471), (F(6)= 3.51, p< 0.00231), respectively. However, the fertiliser treatments were not significantly different (p> 0.05). Tukey’s HSD Test for multiples comparisons found that the mean value of mean height of O. sumatrana was significantly different between spacing S1 and S2 (+ 45.73 cm), between spacing S1 and S3 (+ 78.09 cm), and spacing S1 and S4 (+40.22 cm). Mean collar diameter of O. sumatrana was significantly different between spacing (S1) and S2 (+ 10.21 mm), between spacing S1 and S3 (+ 18.52 mm), and spacing S1 and S4 (+9.77 mm). The mean of mean height of O. sumatrana was significantly different between spacing x fertiliser treatments S1F2 and S1F1 (+ 14.02 cm), and S1F2 and S1F3 (+ 50.59 cm). Mean collar diameter of O. sumatrana was significantly different between spacing x fertiliser treatments S1F2 and S1F1 (+ 5.91 mm), and S1F2 and S1F3 (+ 13.57 mm). There was a positive correlation (r = 0.879) and statistically significance (p < 0.01) between the mean height and collar diameter of O. sumatrana. The highest mean survival of O. sumatrana's was (92.59% ± 26.69), the highest mean height and mean collar diameter were (206.12 ± 68.16 cm) and (43.38 ± 18.82 mm) in the S1F2 treatments, respectively. The early growth performance of O. sumatrana present promising data for forest rehabilitation particularly within open gaps exposed to sunlight in forested areas.
