ARTEAGA MARTINEZ, B.  y  CASTELAN LORENZO, M.. Early dasometric evaluation of an agroforestry plantation of three introduced species, in the municipality of Huehuetla, Hidalgo. Rev. Chapingo ser. cienc. for. ambient [online]. 2008, vol.14, n.2, pp.105-111. ISSN 2007-4018.

An agroforestry plantation was established in Huehuetla, Hgo., México, with three fast growth tropical species: pink cedar (Acrocarpus fraxinifolius Wight et Arn.), melina (Gmelina arborea Roxb.), and teak (Tectona grandis L. f.), to conduct an early assessment on to the survival and growth potential. The experimental design was the split plot blocks, each block consisted on a single site, in which were established nine sites with 25 trees of the three species in each block and different planting densities, 3 x 3, 2.5 x 2.5 and 2 x 2 m. Three blocks were established (sites), resulting a total of 27 plots for the three blocks. Each site had 75 trees of each species, 225 overall. The ANOVA test for the three variables: height, basal diameter and volume showed significant diferences (P≤0.05) in the three sites, after one year of established the agroforestry plantation. According to the Least Significant Difference (LSD) test the best growths of the species were obtained on the site three, associated with coffee and using a level of significance of 5 %; melina had the highest survival (95 %) and growth, followed by pink cedar with 88%; teak recorded the lowest survival (57 %) and growth. Sites one and two, associated with maize showed the least growths for the three evaluated variables and exhibited low survival. In relation to spacing, both, melina and pink cedar had as the most appropriate 3 x 3 m. This agroforestry system or the combination of coffee with melina and pink cedar resulted better than the combination of these two with maize.
