Abstract:In order to evaluate the effect of inoculated Azospirillum lipoferum, Pseudomonas putida and Azotobacter chroococcum bacteria on yield and yield components of corn cultivar SC-704, a factorial experiment under randomized complete block design with 4 replications was carried out in Astara, Iran, in 2009. Seed treatments included inoculation with each of the bacteria as single, double, triple and non-inoculated (control), respectively. The results showed that application of plant growth promoting rhizobacteria increased plant height, grain yield, grain weight and biological yield and in all characteristics there were significant (p<0.05) differences between the bacterial treatments. The increasing number of bacterial inoculations increased average yield and yield components, the highest corn yield of 13,281 kg ha-1 was obtained by triple inoculation of Azotobacter, Pseudomonas and Azospirillum, without inoculation yield was significantly lower (7853 kg ha-1).
