“…Intercropping is an effort to utilize the space between the trees. Post-thinning intercropping can provide space for the remaining stands and intercropping plants (Sudomo et al, 2021). Thus, Superior teak clones with intensive silviculture combined with intercropping can increase the productivity of teak forests.…”

Intensive silviculture plays a crucial role in selecting superior clones with high productivity. The use of superior clones needs to be accompanied by appropriate environmental conditions. The arrangement of growing space is one way for teak clones to grow optimally and produce quality wood products. It can choose initial spacing in the early growth phase and thinning intensity in the later growth phase. This study aims to assess and determine the growth of superior teak clones with different thinning intensities at different planting distances to optimize the growing space. Optimizing growth space also has the potential for intercropping under the stand to produce more diverse products. The research design was a Split-plot design with three blocks as replications. The main plots had four spacings, including 3 m x 3 m, 6 m x 2 m, 8 m x 2 m, and 10 m x 2 m. Subplots were thinning intensity, including 0% thinning (control), 25% thinning (moderate thinning), and 50% thinning (heavy thinning). The results showed that spacing could significantly affect diameter growth. Silvicultural thinning showed significant differences in diameter growth, CADI, height, and volume per hectare. The diameter growth showed higher growth at larger spacing and higher thinning intensity, while the volume per hectare was low. The tree height parameter increased with the thinning intensity. The CADI after two years of thinning increased by 14–42% at 25% thinning intensity and increased by about 35–48% at 50% thinning intensity compared to no thinning at each spacing. Meanwhile, the volume per hectare was lower at wider spacing and decreased at a high thinning intensity. These results indicate an increase in spacing, and thinning accelerates diameter growth and provides better-growing space for intercrops.

“…It shows that thinning can significantly increase DBH growth. Diameter growth is positively affected in the first year after thinning(Sudomo, 2021). It indicates that the diameter increment in the no-thinning treatment decreases with the increasing age of the teak clones.…”

Community forest management for timber production requires short- and long-rotation companion species to fulfill the demands of the timber industry, improve farmer welfare and maintain environmental sustainability. Four species (Falcataria moluccana, Neolamarckia cadamba, Acacia mangium and Gmelina arborea) were tested as short-rotation timber crop companion species for teak (Tectona grandis) on dry-rocky soil in the Gunungkidul community forest. The selection of short-rotation timber species was based on growth performance and survival rate at the teak site. Two years after planting, the viability of G. arborea (87.3%) and A. mangium (78.2%) was significantly (p < 0.05) higher than that of N. cadamba (40.6%) and F. moluccana (18.0%). G. arborea and N. cadamba achieved the best growth in terms of height, diameter, basal area, and volume, with the growth of A. mangium and F. moluccana being significantly inferior. Gmelina arborea has the ability to adapt to teak sites, grow well, and accompany teak. Neolamarckia cadamba demonstrated good growth with potential as a teak companion, and it demonstrated limited drought tolerance on the dry-rocky soils of the study sites. Acacia mangium had a high survival but produced slow growth, indicating that it required an advance evaluation in future years. Falcataria moluccana has different growing site requirements to teak so the performance was relatively poor at the study site. This mixed pattern provides benefits to farmers through commercial thinning of short rotations species, 5–8 years post establishment. Thinning operations will also increase the productivity of residual teak stands. The diversification of timber species in community forests can provide earlier returns, enabling the adoption of silviculture management by smallholders and communities.

Abaca, one of the potential fiber crops with high-quality fiber and promising economic value, is mainly established under the agroforestry system, for it is considered a non-primary crop. The study aims to observe the metabolic and biochemical performance as well as the fiber quality of abaca under the agroforestry system. The experimental design used in this study was nested with two types of agroforestry systems, i.e., intermediate phase (Fase Tengah, FT) and advanced phase (Fase Lanjutan, FL) and was conducted during the rainy season. Parameters observed in this study were divided into edaphic and climatic parameters, oxidative response parameters, foliage macro- and micronutrient, and fiber quality. Despite poor soil quality compared to FL, higher relative humidity (4.35%), lower temperature (2.73%), and lower shading intensity were observed in FT. Improved soil characteristics in FL, viz. soil water content (19.64%), organic carbon (72.89%), porosity (4.29%), cation exchange capacity (13.77%), and pH (35.13%), were unable to compensate plant stress induced by the high shading intensity at 83.99%. Consequently, it contributed to higher levels of malondialdehyde, superoxide anion, hydrogen peroxide, superoxide dismutase, peroxidase, and phenol by 0.07%, 1.86%, 32.66%, 0.08%, 14.63%, and 35.08%, respectively, due to shading stress. Nevertheless, ascorbic acid content in FL was lower (18.90%) compared to FT. Higher fiber diameter (23.53%) and tensile strength (18.77%) of abaca in FT were observed compared to FL. The improved microclimatic conditions under FT promoted the high adaptability of abaca to poor soil quality. Therefore, it contributed to enhanced growth and fiber quality compared to FL. Pruning is pivotal to managing shading intensity.
