The success of transplanting has been an important issue in many restoration programs. The nutritious reserves in the cotyledons of some species can runs out shortly after the completion of the germination. The transplanting delay may lead to the deterioration of the death of the seedlings. Bioposka compost (microbe-enriched compost) were applied as one of the sowing media of three study-tree species. The compost can hold water well and be fertilized, so it were hypothesized to increase the success of the transplanting compared to sands that are commonly used as a sowing media. The research aimed at investigating the effect of bioposka compost to the germination and the seedling growth of the study species. The complete-randomized research design was used for three sowing media: sand, bioposka compost and the mixture of sand:compost (1:1 ratio) with three study species: Syzygium polycephalum, Bouea oppositifolia and Beilsmedia roxburghiana. The variables observed were total and normal germination capacity, first germination, final germination, germination rate, germination simultaneity and seedling growth. The results were analysed using STAR (Statistical Tool for Agricultural Research). In addition, the microbial abundance of bacteria, fungi and yeast in each media were calculated using the spread-plate methods. The germination and seedling growth responses were varied between the different media. The germination capacity and seedling growth of Syzygium polycephalum and Bouea oppositifolia were lower by microbe-enriched compost. By contrast, the germination capacity and the seedling growth of Beilsmedia roxburghiana were not significantly different. Moreover, the microbe-enriched compost application increased the abundance of bacteria, fungi and yeast in the media. Key words: Beilschmiedia roxburghiana, Bouea oppositifolia, Compost, Microbe, Syzygium polycephalum.
