Abstract: This study was conducted at a
bottomland hardwood site with heavy textured soil in Akyazi, Turkey to determine the effect of
initial spacing (3.0 x 3.0, 3.0 x 2.0, 2.5 x 1.6 and 2.5 x 1.2 m) and
post-planting treatments (untreated check, moving, hoeing, disking, and hoeing
plus disking) on early survival and growth of Fraxinus
angustifolia Vahl. One-year
old bare-root seedlings (70?5 cm in height) were hand-planted in December
2004.? Through three years survival was
perfect with a rate of 98% in all treatments. Spacing and the interaction
between spacing and post-planting treatment did not significantly affect
seedling growth through three years.?
However, height and diameter growth increased over time and differed
significantly among post-planting treatments. The hoeing and hoeing plus
disking treatments gave the highest growth, and resulted in about 31% increase
in diameter and height increment, and in total diameter and height about
20%.? These results suggest that
post-planting treatments on bottomland sites with heavy textured soil give promising results.
