Abstract
Formulation is a major step in the successful commercialization of microbial inoculants used as biofertilizers and biocontrol agents.Although formulation research is progressing slowly, several developments including liquid and granular formulations have contributed to the ease of use at the farm combined with the economic benefits of increased crop yield levels. In the present study, the bacterial biofertilizers; Rhizobium, Azotobacter and Azospirillum were formulated with Biogel matrix and the formulated biofertilizers were evaluated for seedling emergence of respective biofertilizers treated width Green gram(Vigna radiata) and Black gram(Vigna mungo L.). The persistence and soil enzyme activity such as Alkaline phosphatase, Urease , total N,P and K content and Nitrate reductase assay was also studied. Biogel matrix formulation of all the tested biofertilizers showed improved persistence and plant growth parameters. The study suggest the possible utilization of formulation of biofertilizers with Biogel matrix.
