Abstract

This research aimed to evaluate three planting densities in the dasometric growth of Gmelina arborea, in Loreto City, Orellana province, in the plantations of the company ARBORIENTE S.A. A methodology was used through a form for the measurement and estimation of the quantitative and qualitative variables, with a completely randomized design with three treatments. Each treatment has three repetitions, with 90 plants evaluated for each treatment. The measurement was carried out at 30, 60, 90,120, 150, 180, 210, and 240 days after planting. The plantation was installed with densities of 3.4x3.4 m, 3x3 m, and 2x2 m. The variables evaluated were diameter at the height of the neck of the seedling, diameter at breast height, total height, crown diameter, branch insertion angle, stem straightness, phytosanitary status, and mechanical damage. The data obtained in the field were subjected to different statistical methods. using Infostat software. The highest value of the diameter at the neck of the seedlings was 3.81 cm, the diameter at breast height with a weight of 6.14 cm, and the crown diameter with its highest value of 3.59. m corresponding to Treatment 1, and the total height obtained its highest value of 4.60 m related to Treatment 2. The quality variable presented that the Gmelina arborea plantation was in excellent condition for Treatment 1 and acceptable for Treatment 1 and 2. The null hypothesis is rejected, and the alternate hypothesis is accepted since the quantitative variables presented significant differences, so subsequent monitoring of the study every six months is recommended.
