Abstract: | The effect of inoculation of Rhizobium or Pseudomonas, or both, in the presence and absence of phosphorus pentoxide (P2O5) fertilizer on wheat yield was tested. The experiment was conducted outdoors in potted soil during two consecutive years under natural conditions. Rhizobial strain (Thal 8-chickpea nodulating bacteria) and Pseudomonas strain (54RB), both indigenous P solubilizers were applied in broth culture at seedling stage. Fertilizer in the form of P2O5 was an additional treatment applied at sowing time. Results revealed that inoculation of Pseudomonas strain in presence of phosphorus (P) fertilizer increased yield up to 41.8% when it was compared with only P fertilizer applied. Co-inoculation of Rhizobium and Pseudomonas strains with the P2O5 treatment however resulted in increased grains yield by 10% over the P2O5 treatment alone. It is inferred that inoculation with Rhizobium and Pseudomonas combined with P2O5 is not only environmentally beneficial but also economically sound and productive, with wheat yield increases of 10% to 42%. |
