Effects of indigenous beneficial microbes formulated as bio-fertilizer on the growth enhancement of tropical tree species, Neolamarckia cadamba

Chemical fertilizer is commonly applied to enhance the growth of Neolamarckia cadamba. However, chemical fertilizer is not user friendly to the surrounding environment. As an attempt to reduce the application of chemical fertilizer, carrier-based bio-fertilizer is introduced as an alternative fertilizer in this study. The effectiveness of biofertilizer in enhancing the growth of Neolamarckia cadamba seedlings were evaluated by conducting rhizopod assay, pot and field trials. Results from this study showed that dual combination of bio-fertilizer with half regime chemical fertilizer treatment had the effectiveness comparable to full regime chemical fertilizer treatment in enhancing the growth of Neolamarckia cadamba.
