Production of acacia hybrid and Acacia mangium seedlings on organic
substrates has carried out at the nursery of Vietnamese Academy of Forest Science. After 90 days sowing the seeds of A. mangium and putting cuttings of acacia hybrid in root containers with eight formulas of substrate, experiment results showed significant differences in height growth of seedlings in these formulas. Substrate formula 1 (coir: river sand, with ratio 2: 1 + 2 gram biofertilizer MF1), formula 3 (sawdust composted: river sand, with ratio 2: 1, + 2 gram biofertilizer MF1) and formula 5 (coir: river sand, with ratio 1: 1, + 2 gram biofertilizer MF1) are the best formulas to produce acacia hybrid and Acacia mangium seedlings
