The use of beneficial rhizobacteria as biofertilizers are best alternatives of chemical fertilizers and might be potential tools for sustainable agriculture. Plant growth promoting rhizobacteria (PGPR) increased crop production by using different mechanisms. Auxin, bacterial phytohormone, plays a significant role in cell elongation, cell division and cell differentiation of plants. The aim of our study was to investigate the native valuable rhizobacteria for growth promotion of wheat and Mung bean plants. The bacterial isolates from different regions of southern Punjab were screened on the basis of their auxin production potential. The auxin production ability was found to be up to 152 ug/ml. Out of 40 strains, 58.8% were gram-positive rods and the rest were gram negative. All the strains were evaluated for their plant growth-promoting potential while being applied on wheat and Mung bean plants, and observed their effect on plant growth promotion under laboratory conditions. These strains showed significant increases (p = 0.05) in root length, shoot length, dry and fresh weight of wheat and mung bean seedlings as compared to control. Our results indicated that PGPR are the best alternatives of chemical fertilizers and have more capability to increase plant growth and yield. It is a cheaper way to accomplish the increasing demand for food.
