This study aimed to develop a mixed plantation strategy, with Sal (Shorea robusta) as the primary tree species, along with four associated and two naturally grown tree species. Using a randomized complete block design (RCBD), the field experiment involved a control group (mono plantation) and three mixed plantation groups, each replicated four times, totaling 80 replicates (40 in 2019 and 40 in 2020). Survival rate, height and collar diameter growth of seedlings were recorded in both mono and mixed plots in July 2021. Statistical analyses, including one-way ANOVA on means from three replicate plots (p<0.05) and a Tukey HSD test, were conducted to assess differences between treatments. Significant differences in survival rates were found among mono plantations, with TMono04 showing the highest survival rate (88% to 91%). However, there were no significant differences in survival rates among seedlings in mixed plantations. Notably, survival rates were lower in mono plantations compared to mixed plantations. Mono plantations showed significant differences in height growth across both 2019 and 2020 plots, with TMono05 achieving the highest height growth (101.1 cm to 123.6 cm). Similarly, mixed plantations showed significant differences in height growth, with TMixed7 displaying the most substantial growth (116.4 cm to 138.2 cm). Overall, mixed plantations showed greater height growth compared to mono plantations. Significant variations in collar diameter growth were noted in both the 2019 and 2020 mono plantation plots, with TMono01 showing the highest growth (10.2 mm to 11.1 mm). Similarly, among mixed plantations, a significant difference in collar diameter growth was observed, with TMixed4 exhibiting the highest growth (10.4 mm to 13.1 mm). Overall, mixed plantations showed higher collar diameter growth compared to mono plantations. The findings suggest that planting Sal trees alongside compatible associated and naturally grown tree species in the Sal forests is preferable over establishing mono plantations.
