Potassium is one of the essential nutrients for plant to growth and required in large amount to achieve optimum growth. Biofertilizer is a good platform to deliver this primary macronutrient by assistance of Potassium Solubilizing Bacteria (KSB).

The optimum growth conditions for KSB based on temperature, pH and initial glucose concentration parameters were studied during this research.
