AB  - Efforts to rehabilitate mangroves often do not yield satisfactory planting results. Low maintenance measures due to the tidal situation of the area make it difficult for rehabilitation actors to carry out fertilization and insertion. This study aims to increase the growth of Rhizophora mucronata with fertilization treatment during planting with various biological fertilizers. The study was designed using a completely randomized non-factorial design with 6 treatments. The results of the study for 5 months showed that the provision of treatment resulted in different plant growth. The biological fertilizer given significantly increased growth in all parameters measured. Trichoderma and mycorrhiza increased plant growth. However, the addition of manure produced a better response both without biological fertilizer and in combination with biological fertilizer. The best response was obtained in the treatment of manure combined with M21microbes and chemical NPK fertilizers for all parameters measured.
