Effect of different biofertilizers on Seed yield of barley (Hurdeom vulgar L.), Bahman cultivar

A study was undertaken to determine the effects of different biofertilizers on growth and seed barley, Bahman cultivar in Iran. The trial was laid out in RCBD with split plot arrangement having three replications during 2011-12 and at Boroujerd, Iran. Treatments were three nitrogen biofrtilizers (Nitroksin, Nitrokara and Supernitroplass) and three phosphate biofrtilizers (Phosphate barvar2, Biozarr and Superplass) with control for them. Results shows thatdifferences between application of different bofertilizers was significant. However, application of Supernitroplass biofertilizer with Phosphate barvar2 treatment has the highest seed yield (7.6 ton/ha) and non-application of biofertilizers treatment has the Pishtaz cultivar has the lowest seedyield (6.3 ton/ha). For give the highest seed yield we should apply both nitrogen and phosphate biofertilizers
