Mean (±95% confidence interval) DBH (A), tree height (B), number of trees (C), and basal area (D) for three methods of site preparation: bedding and planting on ridges (SP-bed), plowing and planting in furrows (SP-furrow), and disc trenching (SP-trench), 12 years after planting. The results of the ANOVA are presented. Different letters indicate significant differences (Tukey’s honestly significant difference test) among methods of site preparation (p < 0.05)
