Biofertilizers are microbial preparations, which help in augmenting crop production by enriching the soil fertility, soil enzymes and soil microbial population. The biofertilizers may play important role in minimizing our dependence on inorganic fertilizers. The occurrence of nitrogen fixing and phosphorus solubilizing bacteria such as Azotobacter, Azospirillum and Pseudomonas, etc. within the rhizosphere of plants of economic importance is being recently harnessed in Indian agriculture. Inoculation of these bacteria has synergic and additive effects on plant growth, besides reducing the cost of cultivation. Hence, it is imperative to popularize the use of biofertilizers, which is a low-cost input technology to reduce the dependence on inorganic fertilizers and contribute to pollution-free atmosphere, which is the need of the day.
