Abstract

In order to evaluate the effect of plant growth promoting rhizobacteria (PGPR) and phosphate solubilizing microorganism (PSM) on yield and YIELD COMPONENTS of WHEAT a pot experiment was conducted at Sari Agricultural Sciences and Natural Resources University during 2009. Experiment was arranged in factorial based on completely randomized design in three replicates. Treatments were included bio-fertilizer in four levels (non-inoculation control, Phosphate Barvare 2 (Pseudomonas fluorescens+Bacillus subtilis), Supernitroplus (Azotobacter brasilense+Azospirillum lipoferum) and Nitroxine (Azospirillum + Pseudomona + Bacillus)), three levels of chemical nitrogen fertilizer (0, 75 and 150 kg urea/ha) and three levels of phosphorus fertilizer (0, 60 and 120 kg super phosphate triple/ha). Results showed that the studied treatments (biofertilizer, nitrogen and phosphate inorganic fertilizers) had significant effect on grain number per spike, 1000 grain weight, GRAIN YIELD, straw yield, biological yield and harvest index. Interaction effect between BIOFERTILIZER and chemical fertilizers was significant in terms of GRAIN YIELD. The maximum GRAIN YIELD was resulted from simultaneously applying of Nitroxine and 75 kg ha-1 nitrogen fertilizer. By contrast, the highest straw yield was obtained when 150 kg nitrogen fertilizer was used. GRAIN YIELD had the maximum correlation with biological yield (r=0.85**). GRAIN YIELD positively and significantly correlated with grain number per spike (r=0.73**), 1000 grain weight (r=0.68**), straw yield (r=0.56**) and harvest index (r=0.69**). In conclusion BIOFERTILIZER inoculations could reduce application of nitrogen and phosphorus chemical fertilizers and increase plant performance.
