“…The tree volume results in the current study concurred with those reported by Goh et al (2013) in Sabah, Khanduri et al (2008) in India and Rahmawati et al (2022) in Indonesia, who examined the growth and volume production of teak provenances at ages in the range 8-11 yr. These studies revealed similar mean value ranges in volume production among different teak provenances.…”

Article InfoImportance of the work: Teak (Tectona grandis L.f.) is of significant economic importance. It was introduced to Tanzania in the early 20 th century for commercial purposes. However, there is limited available information regarding the growth performance of teak seeds obtained from various localities. Objectives: To assess the performance of teak provenances at Longuza Forest Plantation, Tanzania. Materials & Methods:The study employed a randomized complete block design with eight replications, each consisting of six trees, to evaluate 12 provenances of 11-yearold teak trees from 41 families. These trees were planted in the same area with similar climatic conditions. The assessment parameters included survival, diameter at breast height (1.3 m above the base) over bark (Dbh), total tree height (Ht), basal area at breast height (BA), total tree above ground volume (Vol) and the mean annual increment (MAI). The statistical analysis was performed using SAS ® software version 9.4 and its Rank procedures. Results: There were no significant (p > 0.05) differences in survival among the tested provenances. However, highly significant (p <0.0001) differences were observed for Dbh,

Private forest farmers in Semin Village, Semin District, Gunung Kidul Regency transformed the cropping patterns from monoculture to polyculture to meet increasing needs. The farmers planted a variety of food crops to fulfill their short and medium-term needs, and woody plants to meet the long-term needs. Beside this, farmers have processed arrowroot tubers into flour, which can increase household income. The tuber plants apart from being able to live under the shade, have a low glycemic index value so they can be consumed by the diabetics. The method used randomized block design, trials were conducted by cultivating 3 species of tuber plants under the teak shade. Species of tuber plants were arrowroot, canna and yam. The treatments given were: 1) without shade, 2) under 5-year-old teak, 3) under 7-year-old teak. The aim was to understand the relationship between tuber plant growth variables and their environments. Tuber plant growth variables were height and diameter of plant, number of leaves and number of shoot. Environment variables were height and diameter of the teak trees, soil characteristic, and micro climate condition. The relationship was analyzed using linear regression. The results of regression analysis showed that there was a relationship between soil characteristics and plant height (R2=100%), stand height and number of leaves (R2=25.50%), air temperature and number of shoots (R2=22.60%), humidity and the number of shoots (R2=16.70%), light intensity and the number of shoots (R2=14.80%), as well as temperature, humidity, light intensity, percent canopy cover simultaneously and tuber weight/clump (R2=39.10%).

“…Clonal teak plantations were developed to produce timber for construction, with high diameter growth as one of the requirements. Wide spacing increases diameter growth and increases the heartwood percentage, although not significantly (Rahmawati et al, 2022). However, wide spacing reduces the bole height, so it needs to be accompanied by pruning maintenance (Rahmawati et al, 2021).…”

“…It is due to high thinning intensity that can reduce the number of trees per hectare. Stand density affects diameter growth and volume produced per unit area(Vigulu et al, 2019;Rahmawati et al, 2022).Thinning at 25% intensity significantly increased diameter growth while providing a high volume per hectare. Thinning is the principal aspect of silviculture to produce better-quality logs at the end of the cycle(Stewart et al, 2020;Seta et al, 2021).…”

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.
