Abstract
Plant growth-promoting rhizobacteria (PGPR) plays a key role in soil fertility and crop production. Inoculation of PGPR and various organic manures are known to sustain plant growth. Organic carrier materials were meet the requirements of a biofertilizer carrier i.e porosity, lightweight and environmental friendly. The present study describes the synergistic effects of PGPR and different organic carrier materials on wheat growth, physiology, antioxidants and rhizospheric soil properties. Plant growth parameters were increased as plant height (18%) enhanced with the combined use of PGPR and cow dung, while shoot fresh biomass (34%) and leaf area (77%) increase due to the combined use of PGPR + fruits and vegetable wastes. Plant root characteristics including root surface area, root length and root volume were improved due to individual as well as combined inoculation of PGPR and different organic carrier materials. Anti-oxidant enzyme activities related to ascorbate peroxidase (APX) and peroxidase (POX) were also improved due to separate as well as combined inoculation of PGPR and applied organic carrier materials. Chlorophyll a, chlorophyll b, carotenoids, membrane stability index and relative water contents were also significantly improved in all applied treatments. For each parameter combined application showed more promising results. So it can be concluded that various nutrient-rich organic carrier materials and PGPR should be applied in agricultural soils to sustain productivity and support crop production
