In order to study the effects of some biofertilizers with manure utilization, a research has confirmed by factorial experiment in completely randomized block design with 4 replications and 4 factors, Azospirillum , Mycorrhiza , Streptomyces and Manure (dung) was used in which 2 levels of each one (one with and one without using) were applied.
Results showed that Azospirillum and Mycorrhiza , individually, caused significant increase in spike/m2, grain/spike and grain yield. Also mycorrhiza increased 1000 GW significantly. Otherwise manure increased most of characters specially when it used with Azospirillum and Mycorrhiza. Results of threefold and fourfold interctions of experimental factors showed that the use of Azospirillum, Mycorrhiza and Manure increased most of characters but there were a negative or antagonistic interactions between Mycorrhiza and Streptomyces and there were not any antagonistic interactions between Azospirillum and Streptomyces.
