GROWTH OF <em>ACACIA</em> <em>MANGIUM</em> PLANTED ON WINDROW SITES

Abstract

This study was conducted to test the difference in growth performance of Acacia mangium on rich and poor sites created by windrowing as the usual site preparation method for large scale plantations. The experimental plots were laid out in Ulu Sedili Forest Reserve in a one-year-old plantation. Soil samples were analyzed and trees were measured in 1985 and 1989. Basal area development and volume increment as well as timber production were calculated. After one year as well as after five years planting there was a significant difference between dimensions of trees of both sites.
