    Description

    Comparison at age 12 of eight spacings of old-field planted slash pine (Pinus elliottii Engelm.) shows average tree diameter is positively correlated with spacing. Through the seventh year relationship is linear; beginning in the eighth and intensifying through the twelfth year the relationship is curvilinear. Beginning with the eleventh year, tree height is positively correlated with spacing, although the trend is not entirely consistent. There is a positive curvilinear relationship between crown ratio and spacing. Configuration—square versus rectangular spacings—has not affected diameter growth; merchantable cubic volume yield does not yet show a clear relationship to spacing.
