Estudo de biomassa de Tectona grandis L.f. sob diferentes espaçamentos no Estado de Mato Grosso

This work was carried out in the municipality of Sinop, State of Mato Grosso with the objective of evaluating the circumference, total height and biomass production of Tectona grandis plants, in different population densities, obtained with different spacings and planting arrangements. The spacings 3x2 m, 3x3 m, 4x3 m, 4x4 m, 5x3 m, 5x4 m and 5x5 m, were evaluated with the population density varying from 400 to 1.666 plants / hectare. Three trees were selected per treatment, with the individualization consisted of leaves, branches and trunk components. The experiment lasted for 76 months. The increase in population density caused a decrease in teak tree circumference, whereas the height was constant. There was increase in total biomass production of the aerial part of the Tectona grandis plants in the denser spacings, concentrated mainly in the tree trunk.
