Abstract

A experiment was lay out in order to evaluate the effects  of different biofertilizers on yield and yield components of maize at the Lorestan provience, Iran. The experiment was a factorial design with three replications. Treatments were three nitrogen biofrtilizers (Nitrokara (N1), O4 (N2), O6 (N3) and control (N4)) and three phosphate biofrtilizers (Phosphate barvar2 (P1), Biozarr (P2), Mc1+p5 (P3) and control (P4)).Yield and yield components were determined. Results showed that that there were significant differences in the response of maize to the effect of treatments on yield and its components, but there was non significant differences in HI for two type of biofertilizers. However, maize yield and it components was significantly higher in application of biofertilizers treatments. The highest grain yield was belonged at application of MC1+B5 and the lowest grain yield was belonged at application of phosphat barvar2. Interaction between NÎP  shows that N3P3 treatment has the highest grain yield and the N4P2 treatment has the lowest grain yield and the differences were significant. In final results of this study reviled that application  nitrogen and phosphate biofertilizers increased yield and yield components of maize under Boroujerd environmental condition
