Mangrove nursery protocols are essential for sustainable reforestation. Seedling generation of various mangrove species is required to re-establish the coastal and mangrove biological systems. This research assessed the growth and survival of Avicennia marina and Bruguiera cylindrica in a nursery using di!erent substrates: sand (sand) as Treatment I, mangrove soil (clay) as Treatment II, and their mixtures (sandy-clay-loam) as Treatment III for 18 weeks. The experiment was arranged in a randomized factorial design, with two mangrove species, three substrates, and $ve replicates. Each replicate has 10 mangrove seedlings or propagules. Analysis of variance showed a signi$cant di!erence in survival between sand (82 ± 20%) and sand-clay-loam (48 ± 08%) in A. marina (p < .05). Sand also yielded signi$cantly higher survival (93 ± 6%) than mangrove soil (67 ± 23%). The total height, number of axils, and number and lengths of internodes in A. marina were not signi$- cantly a!ected by substrate types (p > .05). However, the number of leaves (p < .05) and internodes (p < .01) produced by B. cylindrica were higher in mangrove soil. Mangroves A. marina and B. cylindrica have been successfully grown in all substrates tested. More importantly, the two species’ seedling performances di!ered among substrates. Therefore, it is recommended to use sand soils for the nursery of A. marina and B. cylindrica when conducting actual plantations because the survival rate was signi$cantly higher in the sand than in the other substrates. In contrast, results suggest that mangrove soils might positively a!ect the growth of B. cylindrica in terms of leaf and internode production; hence, they could be used alternatively.
