Nitrogen and phosphorus are essential for the normal functioning of plants, as it participates in the composition several biomolecules. The continuous application of these elements through inorganic fertilizers to agricultural field affects the soil environment. It is directly affected the sustainable growth crop plants. The use of plant growth-promoting bacteria (PGPB) may be an alternative to reduce the usage of chemical fertilizer or inorganic fertilizers. Thus, using beneficial microorganisms that promote efficient growth from seedling to plant is relevant in the crop production system, especially in regard to the organic system, which is dependent on alternative inputs. Under nursery conditions, the applications of Azospirillum and PSB have the beneficial effect on growth, development and biochemical characters of green gram. The beneficial effect was higher in dual inoculation of biofertilizers rather than single application. Further, the effect was comparable to urea as inorganic fertilizer. Hence, the response of dual application of biofertilizers (Azospirillum and PSB) as organic fertilizer is comparable the urea as inorganic fertilizers.
