Since the chemical fertilizers cause severe environmental and relatively long-lasting pollution,bio fertilizers can be used to supplement and replace chemical fertilizers. To evaluate the effect of the vesicular-arbuscular mycorrhizal fungi and phosphate solubilizing bacteria on growth parameters of Sadri rice, seeds after inoculation with bactria, were cultured in pots containing the fungi in the soil (including inoculation with bacteria Pseudomonas fluorescens and P. putida، in combined inoculation with the fungus Glomus mossea and non microorganisms).The results showed that biofertilizers improved all the features evaluated Including: plant height, diameter, length and surface of roots, leaf area, shoot and root dry weight compared with the control. All of them, the inoculation with P. fluorescens bacteria and combined incubation Glomus mossea fungi and P.fluorescens had a significant increase in all evaluated attributes than other treatments. Therefore, we conduce biofertilizers as plant growth stimulators to improve plant nutrition and its growth. This would reduce the use of chemical fertilizers and could be an effective step towards sustainable agriculture and environmental preservation.
