What is PGPB?

PGPB are plant growth-promoting bacteria, commonly known as any bacterial responsible for the nutrient transfer to the plants. The role and importance of bio-fertilizers in sustainable crop production have been studied well.

Biofertilizers play a very significant role in improving soil fertility by fixing atmospheric nitrogen, both, in association with plant roots and without it, solubilise insoluble soil phosphates and produces plant growth substances in the soil.
