Abstract:

The research work was undertaken to develop solid and liquid based Azospirillum formulations using different additives. It was observed that different additives in the formulation supported the growth of Azospirillum in the formulations. Survivability of Azospirillum formulation in solid/liquid formulations were analyzed by storing them under ambient and refrigerated conditions. Population was estimated at 30, 60, 90, 120 and 180 days after inoculation. Maximum numbers of colonies were observed in liquid based formulations (85 x109 cfu/ml). In general the population of Azospirillum was more in the formulations which were stored under refrigerated condition compared to room temperature. The developed formulations were tested on maize for their plant growth promotional activity under pot culture condition. The liquid based Azospirillum formulation 1 @ 5 ml/kg seed performed better followed by liquid based Azospirillum formulation 2 @ 5 ml/kg seed. Among the solid talc based formulations, the formulation 3 @ 500 g/ha performed better.
