Evaluación del efecto de la fertilización en el crecimiento inicial de Gmelina arborea roxb, en el cantón Loreto, provincia de Orellana

Abstract

This research was carried out due to the problems presented on the ARBORIENTE S.A. farm, particularly on the variability of the soil since the development of the plant is uneven, even though they have been planted simultaneously. This study aimed to evaluate the effect of fertilization on the initial growth of Gmelina arborea Roxb. in the Loreto canton, province of Orellana. A methodology was used through a format for the measurement of quantitative variables with an incompletely randomized design with three treatments. Each treatment had four repetitions, and the control had two repetitions, with a total of 80 plants evaluated for each treatment and 40 plants evaluated by the controls. The measurement was carried out 40, 80, and 120 days after planting. The plantation was established at a density of 3.4 x 3.4 m with a low fertilization dose (166.6 g), medium (222.1 g), and high (277.7g), which was applied three times. The variables evaluated were diameter at breast height, total height, and leaf area. The data obtained in the field were subjected to different statistical procedures using the Infostat software. The highest value of the other variables was the diameter at breast height of 9.36 cm of the control (T4), 7.20 m in T1, which is the low dose, and the leaf area in change, the highest value was 28.31. Finally, the alternative hypothesis is accepted, and the null hypothesis is rejected because the quantitative variable (height) presented significant differences, so it is recommended to monitor the plantation to observe whether the changes are more significant over time.
