Bio fertilizers are commonly called microbial inoculants which are capable of stoping important nutritional elements in the soil from non- usable to usable form by the crop plants through their biological processes. For the last one-decade, biofertilizers are used in large quantity as an eco-friendly approach to reduce the use of chemical fertilizers, improve soil fertility status and for improvement of crop production by their biological activity in the rhizosphere. The seeds of Vigna mungo were treated with bio-fertilizers for 45 days as compared to untreated. It was observed that the seeds treated with experimental bio-fertilizer Rhizobium showed excellent result in the morphological and bio-chemical parameters.
