ABSTRACT

The effects of initial tree spacing on bark and wood yield of black wattle (Acacia mearnsii De Wild) were studied. The experimental design was a complete block with four replications. The tree spacing treatments were of 1 x 1 m; 3 x 1,33 m; and 3.0 x 2.0 m. The smaller spacing is, the bigger the yield of bark and wood is. However, it was observed higher plant mortality and smaller stem diameter.
