Statistical Analysis
Factorial Randomized block design was used to analyze the experimental data as per the procedure illustrated by Gomez and Gomez (1984). The tree species and year after reclamation were kept as two factors with three and two levels (some cases three) respectively. Finally, for pairwise comparisons, the Duncan’s Multiple Range Test (DMRT)was used. All of this analysis was conducted on R-software with help of r-package ”Agricola” (Mendiburu, 2020).
