Figures & data
Figure 1. Biofertiliser technology employs plant-microbe interactions in influencing plant growth and development.
Notes: The beneficial rhizospheric microorganisms supply nutrients by fixing nitrogen, solubilising phosphorus and by producing plant growth promoting substances such as indole acetic acid, gibberellin and cytokinin.
