Fig. 4. Seedling emergence percent at different seed sowing depths. Error bars represent ± 1 standard error of the mean. The symbols * and *** represents significant difference at p ≤ 0.05 and p ≤ 0.001, respectively, between two species at each depth (independent sample t-test). Different alphabets ‘a, b’ and ‘p, q’ represent significant difference among soil depths within Senegalia catechu and Leucaena leucocephala, respectively (p ≤ 0.05, one-way ANOVA).
