Intensive application of agrochemicals leads to several agricultural problems and poor cropping systems. The extensive research program on beneficial bacteria and fungi has resulted in the development of a wide range of bio-fertilizers, which satisfied the nutrient requirements of crops and increased the crop yield
as well.In the present study;variousPlant Growth Promoting Rhizobial Bacteria from the 6 soil samples were isolated, characterised and stored. PGPR- Biofertilizer was prepared by mixing isolated PGPR-BACTERIA with various compounds. Seeds of Bengal gram,Green gram and Chicken peas were collected and treated with
biofertilizer; controls (without biofertilizers) also were maintained for comparison. Biofertilizers (Azotobacter, Pseudomonas, Enterobacter,Bacillus, Phosphobacteria and Rhizobium) were used alone as well as in combination of all inoculates. Seeds were sown in cups and grown in three batches. The growth and yield parameters of those plants such as length of root and stem, leaves count, total chlorophyll, carotenoid and protein content were observed.The total chlorophyll and carotenoid content in plants were estimated. High chlorophyll, carotenoid and protein content were observed in Rhizobium inoculants when compared with other inoculants. High chlorophyll content was observed in Chicken peas and high carotenoid content in Green gram and Chicken peas. High chlorophyll was observed in Chicken peas. High protein content was observed in T5 and low protein content was observed in T2 when compared with other inoculants, Chicken pea showed high protein content and Bengal gram showed low protein content
