Evaluation of bacterial strains for developing effective plant growth promoting strain on chickpea growth and physico chemical properties of soil

The study was intended to isolate and characterize the plant growth-promoting properties. A collection of microbial consortia called plant growth-promoting microorganisms (PGPM) work to increase crop growth and yield through a variety of direct mechanisms, including as nitrogen fixation, phosphate solubilization, synthesis of PGH, ammonia, and siderophore, as well as indirect mechanisms. The aim of the study was to evaluate the impact of bio fertilizer on Chickpea growth and soil health. Five bacterial strains were utilized for this purpose. Pot study was conducted at arid zone research center D. I. Khan. The results showed that treated pots with inoculation of rhizobium strains plus organic amendments showed greater results as compared to control treatment. The highest value of plant height, shoot fresh and root fresh weight (34.cm)(39.66g)(6.00 g)were found in treatments T2 ( Mesorhizobium ceceriplus compost)T6 (Pesodomonas putida wheat straw)as compared to control treatment. The study found that rhizobacterial strains treated plots significantly increased chickpea crop growth. Treated pots showed that using Rhizobacterial strains have increase chickpea crop growth and improve soil nutrient absorption from soil. As a result, the combination with (Rhizobacteria plus organic amendments) increases soil Nitrogen and Phosphorus content. It may be concluded from the study that using PGPR Mesorhizobium ceceriplus compost and (Enterobactor moriplusLentil straw) increases soil nutrient absorption form soil while also improved chickpea growth parameters.
