Abstract:
In today’s sustainable farming increasingly used phrase is "biofertilizers." Existing approaches are improving, and numerous new strategies have emerged to enhance their effects on plant systems. Bioformulation is one of the most important areas of research since it impacts the efficacy of inoculants. An effort has been made to improve bioformulation in the hopes of decreasing contamination and extending shelf life. Rhizobium is a symbiotic Nitrogen fixing bacterium that fixes atmospheric N₂in legume root nodules while also benefiting its host plants. In this research, different technologies were employed to produce the biofertilizer formulation. The purpose of this research was to establish inoculant formulations with higher population using acceptable carrier material. Rhizobial culture has been utilized as model organism and water soluble powder formulation were made using freeze drier and fluid bed drier. Among different carriers (Mannitol, Maltodextrin and Dextrose) evaluated. Mannitol based carrier formulation showed the best result than other two carriers in terms of viable cell count. These formulation were compared with the commercial lignite based formulation and liquid formulation, the results showed that freeze dried formulation resulted significantly higher population (log14.30cfu/g) than the other formulations.
