Abstract
The agricultural sector in Malaysia is moving towards environmentally sustainable
practices. Biological Nitrogen Fixation (BNF) process can be adopted to minimize the
usage of inorganic N fertilizer. The biological nitrogen fixation process occurred when
the diazotrophs are inoculated to the agricultural crop and establish beneficial symbiotic
or non-symbiotic relationships with the host plants. The interaction between plant and
diazotrophs would also influence synthesis of phytohormone (indole-3-acetic acid).
Generally, IAA excreted by the bacteria would increase top and root biomass and lateral
root numbers of the host plants. Thus, combination of both BNF and synthesis of
phytohormones of the diazotrophs would finally improve yield of the host plants.
Therefore, the beneficial diazotrophs have the potential to be introduced to tissue
cultured oil palm under in vitro and glasshouse conditions.
