“…The inoculation of Rhizobium and rhizospheric bacteria separately raised nitrogen supply to plants due to gain in nodule formation, and they supported the activity in the rhizosphere [13,42]. These results are well matched with the findings of [11,55], who observed a rise in nutrient contents in the root, shoot and grain of different crops upon inoculation of PGPR. A consistent approach to improve nutrient availability is to admit the benefits of PGPR and their nutrient-solubilizing ability.…”

“…Biofertilizers promote plant growth by supplying nutrients through biological nitrogen fixation or by increasing the availability of insoluble nutrients in the soil and by the synthesis of growth-promoting substances [9,10]. Microorganisms such as nitrogen-fixing and phosphate-solubilizing bacteria tend to change-over atmospheric nitrogen to plant-accessible form and production of enzymes and solubilization of the insoluble phosphate from organic and inorganic phosphate sources [11].…”

Wheat is the third largest grown crop after maize and rice worldwide. Integrated use of chemical and biofertilizers have the potential to improve crop yield and quality due to their growth-promoting attributes. Therefore, the present study planned to evaluate the effectiveness of endophytic (Paenibacillus sp. strain (ZE11), Bacillus subtilis (ZE15) and Bacillus megaterium (ZE32)) and rhizobacterial strains (Bacillus subtilis (ZR2) Bacillus subtilis (ZR3) and Bacillus megaterium strain (ZR19)), solely and in combination, to increase the productivity of wheat and microbial activity in the rhizosphere. The maximum increase in microbial biomass carbon (44%), available phosphorous (30%), ammonium–nitrogen (24%), nitrate–nitrogen (37%), iron (10%), zinc (11%) and bacterial population (31%) was recorded by co-inoculation of ZE11 + ZR3. Subsequently, co-inoculation of ZE11+ZR3 showed a maximum increase of 31%, 29%, 30%, 27%, 33%, 30%, 25%, 9%, 15%, 9%, 18% and 26% in superoxidase dismutase (SOD), peroxidase dismutase (POD), catalase (CAT), ascorbate peroxidase (APX), polyphenol oxidase (PPO) and peroxidase (POX), grain yield, nitrogen, phosphorous, potassium, iron and zinc in grains, respectively, as compared to uninoculated control. The sole inoculation of ZR19 showed maximum harvest index (45.5%). The sole inoculation of endophytes and rhizobacteria has a significant effect on growth, physiology, and wheat crop yield. However, co-inoculation had a better effect and can be used to develop multi-strain biofertilizer to promote growth and yield of crops.
