Use native common bean rhizobia as biofertilizers that can stimulate the growth of common bean plants and contribute to
the N and P plants nutrition
The impacts of chemical fertilization on the environment makes itan unsustainable way to grow our food over the long term unlikemodern agriculture
Common bean production is mainly based on the use of chemicalfertilizers because this crop presents many limitations such as itslow capacity of symbiotic nitrogen fixation

Also the combined inoculation enhanced growth parameters but results varied depending on the P levels
These results may contribute to Explanation of the importance of P requirements for nodule formation and their efficiency in inducing plant growth
