The study was conducted in Elazig-Sivrice, southeastern Turkey. Data were collected from six sample plots, and stem analysis for each species in the mixed stand was performed to reveal the growth and development of the basal-area-averaged trees. Statistical analyses showed that the pure P. nigra stands were superior to the mixed stands in terms of wood production (236 m(3) ha(-1) vs. 150 m(3) ha(-1)), wood economic value ($19,551 ha(-1) vs. $11,483 ha(-1)), and C sequestration (93 t ha(-1) vs. 64 t C ha(-1)) at 54 years old. The lower values calculated for the mixed stand may have been due to the incompatible growth curves of the two species. These results imply that if the aim is to obtain wood products, pure P. nigra stands may be more advantageous than mixtures of C. libani and P. nigra for afforestation.eninfo:eu-repo/semantics/closedAccessGrowth traitsafforestationcarbon sequestrationwood productionmixed forestsstem analysisArticle10.1080/02827581.2023.2219461385344351WOS:0009999941000012-s2.0-85161400905Q2Q2
