Abstract : Field evaluation of nursery bed inoculated with Glomus fasciculatum and root dip treatement with Azotobacter chroococcum and Aspergillus awamori was carried out on aerobic rice. All the inoculated treatments with G. fasciculatum either singly or incombination showed increased growth and yield of rice compared to control and dual and triple inoculation were performed better than single inoculation treatment. G. fasciculatum inoculated seedlings in nursery bed shown better root colonization in field after transplantation compared to un-inoculated plants. The root dip inoculation with A. chroococcum and A. awamori during transplantation also increased the population of N 2 fixer and Phosphate solubilizers besides increasing the population of general microflora in the rhizosphere. The results revealed the possibility of nursery inoculation of arbuscular mycorrhiza and root dip inoculation of other biofertilizers for aerobic rice.
