Abstarct: Mycorrhiza fungi and phosphate solubilizing bacteria are terrestrially useful microorganisms, as biofertilizers, providing nutrient for plants. The present study was implemented in order to investigate the effectiveness of mycorrhiza (Glomus intraradices) and phosphate solubilizing bacteria (Phosphate biofertilizer Barvar-2) under different levels of phosphorus on Yield and Yield components of chickpea (Hashem cultivar) was measured in 2009-2010 at Shahrood University of Technology. Experiment was conducted as split plots factorial in a complete randomized block design with three replications. The main plot was phosphorus at three levels (0, 25 and 50 kg/ha) and mycorrhiza and phosphate solubilizing bacteria were the subplot randomized together as factorial experiments. Mycorrhiza in two levels, including inoculation of mycorrhiza and non-inoculation mycorrhiza and phosphate solubilizing bacteria was at two levels, inclusion and exclusion of bacteria. The results showed the effect of mycorrhiza inoculation on plant height, biological yield, seed hundred weight, number of pods per plant, root colonization and seed phosphorous were significant. Phosphate solubilizing bacteria had no significant effect on traits. The increase of phosphorus fertilizer alone increased the biological yield, grain yield, available soil phosphorus, seed phosphorous and leaf area per plant. Root colonization decreased with increasing phosphorus fertilizer. The interaction effect of phosphorus fertilizer and mycorrhiza inoculation on the number of pods per plant was significant. As well as two factor fertilizer phosphorus and phosphate solubilizing bacteria inoculation on seed phosphorous and interaction three factors on the number of pods per plant was significant. The results showed the effect of mycorrhiza inoculation on yield (under low soil phosphorous level) was equivalent to use of 50 kg/ha of phosphorous chemical fertilizer. The result is very important in organic farming, suggesting replacement of mycorrhizal inoculation with application of phosphorous chemical fertilizer.
