Abstract:

Aimed to verify the volumetric production per unit area, growth in height and diameter at breast height (DBH) in Eucalyptus urophylla x E. grandis W. Hill. Stands, in different reduced planting spacing in southwest Goiás. The work was implemented at the Experimental Farm of the Federal University of Goiás, Jataí Regional (UFG/REJ), Jataí-GO municipality, following the assumptions of a completely randomized design, with six treatments, and three replications, totaling 18 plots, with planting 50 seedlings per plot. The evaluated hybrids were AEC1528, I144 and GG100 and the evaluated spacings were 3.0 m x 0.5 m and 3.0 m x 1.0 m. Thus, it was observed at 33 months of age that growths in diameter and height are directly affected by the densification of the plants, and consequently with the reduction of available useful area for each plant. The 3.0 m x 0.5 spacing in energy forests affects the individual increment for both diameter and height as well as volume. The hybrids differentiation occurred for the increase in height and production, where the hybrid I144 stood out. The highest expression in volumetric production for bark wood without bark and bark volume was observed for the 3.0 m x 0.5 m spacing.
