Abstract

     This study was carried out to investigate poplar and paulownia’s growth under different spacing in a 5-year plantation located in Mazandaran wood and paper company’s fields in Sari-Iran. The trees were planted in three different spacing: 3×3m, 4×4m, and 5×5 m, each established in 3 replications. The quantitative parameters including DBH and Height were measured and a comparison was made between the stands height and diameter growth. Survival percentage was also calculated across the stands. The averages were statistically compared in a randomized block design in two forms: 1) two species were separately compared in their threefold spacing, and 2) two species were crossed in each spacing. Tukey’s test was used to compare the averages. Results showed a promising rate of survival over the stands. Moreover, the growth was significantly different amongst different spacing of the stands, representing the best growth in 3×3m spacing. In addition, the height of poplar was significantly more than those of paulownia, though the diameter growth assessment showed a reverse trend between the stands.
