Due to its global conservation status as endemic and endangered species, propagation and conservation of Teak (Tectona philippinensis) is a very urgent matter to address. Clonal propagation method was tried to save the species extinction. Successful rooting of the species had been achieved (Follosco-Edminston, 2000). The next step is to enhance the growth of seedlings using biofertilizers. Significant differences were obtained on seeding height, diameter, % dry matter, % organic matter and % N. Height of rooted cuttings is found best with Biocore at 20 gram/seedling giving 36.06 cm over that of the control at 20.28 cm. Seedling height, under a combination of Biocore + Mykovam was 25.30 cm. Biocore applied at 20 gram/seedling significantly yielded the biggest seedling diameter. Analysis of tissues also revealed significant differences in % dry matter, % organic and % nitrogen contents among different treatments. Mykovam treated seedlings gave the highest (63%) dry matter content while Biocore-treated seedlings at 20 g had the lowest (41%). Organic matter content was high (23.61%) under Biocore treatment at 20 grams while Mykovam treatment yielded the lowest (19.83%) however, this is not significantly different from the results obtained under Biocore at 10 g and the control treatment. Accumulation of % N had the same trend with those of the % organic matter found in the plant tissues. It is therefore evident that the addition of biofertilizers, Mycovam and Biocore enhance T. philippinensis growth and survival in the nursery. Biocore added at 20 g/seedling gave the best results
