This study was conducted to determine the effects of different site preparation and weed control treatments on three-year seedlings’ growth performance and survival ratios of narrow leaved ash plantation sites. Two different site preparations (conventional and systemic herbicide application) and five different weed control treatments (the control, one-year land clearing, two-year land clearing, one-year herbicide and two-year herbicide) were tested in a split-plot experimental design. According to the ANOVA, site-preparation treatments did not have a significant effect on any dependent variable of seedlings. Except the control treatment, height and diameter increments of seedlings were similar. Height and diameter increments were found 56% and 43% higher in weed control treatments, respectively, than that in the control. Except for the two-year land clearing treatment, volume of seedlings were similar, with a 53% higher than that in the control. As a result, there were no significant effects on seedling growth for site preparation treatments. However, significant differences were found for weed control treatments. It has shown that weed control shall be carried out although tall seedlings are used for planting. Herbicide usage can be preferred instead of conventional site preparation and weed control methods since it is more economical and more practical.
