Abstract

This experiment was laid out in order to evaluate the effects  of different biofertilizers on yield components of barley. The experiment was a factorial design with three replications. Treatments were three nitrogen biofrtilizers (Nitroksin, Nitrokara and Supernitroplass) and three phosphate  biofrtilizers (Phosphate barvar2, Biozarr and Superplass) with control for them and yield components were determined as standard. Results showed that, effect of Nitrogen bio fertilizer on number of grain per spike, 1000 grain weight, grain yield and biomass was significant. The effect of Phosphate bio fertilizer on grain yield and biomass was significant and the interaction between them on number of grain per spike, 1000 grain weight, grain yield and biomass was significant. Among the nitrogen biofertilizers, Nitroksin treatment has the highest grain yield and biomass  and control treatment has the lowest of them. However, barley yield and it components was significantly higher in application of biofertilizers treatments. In final results of this study reviled that application  nitrogen and phosphate biofertilizers increased yield and yield components of barley under Boroujerd environmental condition.
