Keywords:
Silvicultural treatments, thinning, growth.Abstract
This study aimed to show the effect of silvicultural treatments to improve the health and productivity of forests mecrusse (Androstachys johnsonii Prain, 1. c.), in the Mabote District of Inhambane province. The experiment design was based on a complete randomization design, comprising of a group of three plots (20 m x 50 m) and three treatments (Control - C, phytosanity - P and thinning - T). The results showed that the silvicultural positively treatments influenced the health and growth. The periodic annual increment (PAI) observed during the period under review was 1.22 mm year-1. There was an PAI of 1.3 mm for the treatment phytosanity (P) and thinning (T), and 0.9 mm year-1 for the control plots. The interventions did not affect the structure of the stands for the diameter distribution since remained the j-reverse shape.
