Abstarct: This study aimed to investigate the effect of mycorrhiza and bio-fertilizer Ryzvbyn Brbrkhy of functional components of two varieties of cowpea, in the Khuzestan province in a farm located in the Susa Daniel in 1393 as a factorial in a randomized complete block design with four replications. The treatments included two varieties of cowpea (trust and creamy) as the first factor, mycorrhiza in three levels (control), inoculated species (G.Intraradiches) and inoculated with S. (G. Mossea) as the second factor and treatments and lack of Ryzvbyn biological fertilizer was applied as the third factor. A comparison of average grain yield and biological yield of both cultivars in all treatments examined in this study showed that the highest grain yield, biological yield and harvest index was seen in the cream without the use of mycorrhizal fungi. However, most biological function in the worm affected the biological fertilizer Ryzvbyn result that reflects the positive impact of this variable is the trait. The percentage of nitrogen in the trust earns the highest in between two varieties is that this amount has been achieved in the absence of mycorrhizal fungi and Ryzvbyn fertilizer, while the percentage of plant proteins in the trust, in the absence of fungi and bacteria highest in between the two varieties have had. The highest seed weight in the consumption of beans in cream varieties of bacteria were seen.
