Abstract

To study the effects of Plant Growth Promoting Rhizobacteria (PGPR) on yield and YIELD COMPONENTS of bread wheat under irrigated and normal stress conditions, an experiment was conducted at Ilam Agricultural Research Station, in 2009-2010. The experiment was arranged as split-plot in RCBD (Randomized Complete Block Design) in four replications. Cultivars of Chamran and Verinak were allocated to main plots and four levels of biofertilizer including both AZOTOBACTER biofertilizer, Pseudomonas, that's, without biofertilizers and two levels of irrigation (normal irrigation and its termination) were arranged in sub plots as factorial experiment. The results showed that the variety of all the traits were significant except the biological yield. Verinak cultivar produced higher seed yield (4565.4 kg/ha) than Chamran cultivar (4112.5kg/ha). The irrigation had significant effect only on seed yield, weight of 1000 seeds, and harvest index. The biofertilizer levels had significant effect on all of the traits and both of biofertilizers produced higher seed yield (4758.3kg/ha) than others. Among double and triple interactions, only the interaction between variety and biofertilizer was important on the number of spike per m2 and other interactions were not significant. Finally, in this study, results showed that the highest seed yield was obtained using both of the biofertilizers in Verinak cultivar and lowest yield was produced in no biofertilizers in Chamran cultivar.
