Growth and yield of teak stands at different spacing

Abstract

The objective of this work was to evaluate the growth and yield of teak (Tectona grandis) stands at different spacing and in different soil classes. Twelve spacing were evaluated in an Inceptisol and Oxisol, in plots with an area of 1,505 or 1,548 m2, arranged in a completely randomized design with nine replicates. The teak trees were measured at 26, 42, 50, and 78 months of age. Total tree height was less affected by spacing. Mean square diameter was greater in wider spacing, whereas basal area and total volume with bark were greater in closer spacing. An increase in volume with bark per tree was observed with the increase of useful area per plant. For teak trees, growth stagnation happens earlier, the growth rate is higher in closer spacing, and the plants grow more in the Inceptisol than in the Oxisol.

Effect of spacing on growth, carbon sequestration, and wood quality of 8-year-old clonal teak plantation for sustainable forest teak management in Java Monsoon Forest, Indonesia

“…Narrow spacing has a higher tree height value than wide, except for spacing 3 m x3 m, and this is consistent with Berrocal et al (2020), where stand density also showed a statistically significant effect not only with DBH but also with high growth (Berrocal et al 2020). Differences in height growth in teak were influenced by site quality (Cardoso et al 2013;Medeiros et al 2018) and genetics .…”

Space Planting, Competition, and Productivity of a Seven-Year-Old Clonal Teak Plantation in the East Java Monsoon Forest Area

“…This finding also suggests that In contrast, spacing has no significant effect on the height growth of teak (p-value) (Table 3), with the best of spacing for height growth being 8 m × 2 m (Figure 8). This result may have occurred probably because height growth is affected by site quality (Malimbwi et al, 1992;Cardoso et al, 2013;Medeiros et al, 2018), thereby indicating that the height growth of teak is not affected by stand density (Cardoso et al, 2013;Medeiros et al, 2018), but the height growth is sensitive to differences in site quality. Ola-Adams (1990) examined the effect of spacing on the growth and yield of Tectona grandis and Terminalia superba.…”

Simulação da produção por sortimento de madeira em povoamentos de <i>Tectona grandis</i> L. na região norte do estado do Mato Grosso

“…Verifica-se, no entanto, que os povoamentos de Teca apresentam produtividade variável, muitas vezes relacionada à seleção de sítios impróprios para o desenvolvimento, práticas de manejo e seleção do material genético inadequados (MEDEIROS, 2018). Segundo Rocha et al (2015), ainda há falta de informação e pouco investimento em pesquisa sobre a Teca relacionadas às práticas silviculturais, como a condução de plantios comerciais, características edafoclimáticas específicas e viabilidade econômica da atividade.…”
