Experiment was conducted to evaluate the effect of different fortified formulations on growth of maize and soybean grown under green house condition. microbial inoculants such as Azotobacter chroococcum, Bradyrhizobium japonicum, Bacillus megaterium and Acinetobacter calcoaceticus were fortified with the fortifying materials like Gibbrellic acid, PVP, PEG, glycerol, trehalose and ZnSO4. Optimum concentration of fortifying materials for each organism were determined and fortifying combinations was developed. The two best fortified combination were found to be C1 having GA3+PVP+PEG+ Glycerol+Trehalose and C2 having GA3+PVP+PEG+Glycerol. These two combinations were selected for development of liquid, carrier, alginate beads and pellet formulations then these formulations were tested on growth of maize and soybean under green house condition, the growth of maize and soybean were significantly influenced by the inoculation of fortified microbial inoculant formulations. Among the four different fortified formulations tested liquid fortified formulations showed better growth compared to other formulations. The next best were carrier, alginate beads and pellet formulations. The lowest plant growth was recorded in the control plants.
