Evaluation of growth Tectona grandis l. f. in a silvopastoril system in the area Mina Chica, canton Velasco Ibarra, province of guayas

Abstract

The research was conducted in Mina Chica, Velasco Ibarra canton, Guayas province, in a plantation of Tectona grandis L. f., five years old, established in an agrosilvopastoral system, the sampling intensity for the inventory was 23%, this represented an inventory of 3 strips that determined the results of the average diameter of 13.16 cm, the commercial height of 3.33 m and the total height of 10.33 m, the average commercial volume was 0. 061 m3 per tree and the average total volume was 0.17 m3, with 81 trees per strip and 1053 trees for the 13 strips that determined one hectare of plantations, average annual increase in diameter was 2.63 cm, commercial height was 0.66 m and commercial volume was 0.012 m3. To determine the quality of the trees, they were evaluated based on their phytosanitary status in three classes A, B and C, being the A category excellent, B good and C bad, to obtain the number of individuals per diameter class, ranges were established; for A greater than 15.10; B 12.10 to 15.00 and C less than 12.00 cm, this allowed to have a data of the categories and to know the number of trees to thin in category C, a management plan proposal was determined for the coming years with the pasture, animal and forestry components.
