The comparative effect of bacterial biofertilizers such as Rhizobium, Phosphobacteria and Azozpirillum on growth and yield of green gram (Phaseolus radiata L.) and cowpea (Vigna siensis Edhl.) was studied. The bacteria were isolated from the soil samples and identified by staining and biochemical tests. The seeds were inoculated with bacterial biofertilizers with various treatments and showed in sterile polythene bag containing sterilized soil. After 65 days of plant growth, the morphological and bio-chemical parameters of cowpea were increased in combined inoculation of Rhizobium, Phosphobacteria and Azospirillum than green gram plants.
