Abstract
The relationship between the growth rate of Eucalyptus grandis and initial spacing was studied in a replicated spacing trial correlated Curve Trends (CCT) on the coastal plain of Zululand. The parameters of the Richard~ growth equation, applied to live basal area, were regressed on nominal stand density, An asymptotic regression was fitted to the observed mean diameters, the estimated parameters of which were subsequently regressed on Nnom An analysis of height growth revealed that mean height as well as top height are related to stems per hectare. Measurements of crown width and crown length served to evaluate the effect of stand density on crown parameters.Keywords
