| Abstract | ||||
| Pot experiments were conducted to study ~he effect of individual or mixed inoculation with R. legumlnosarum bv. Viceae, A:rotobacterchoroccum and phosphate dissolving mycorrhiza (VAM) used to inoculate (aba bean infected or n n - infected with board bean stain virus (BBSV). App(ication of Rhizobium alone Of in combination with either Azotobacter or mycorrhiza led to a significant Increase in number and dry weight of nodules, and dry weight of shoots and its total nitrogen content on both healthy or viral infected plants in comparison with their corresponding control. The increase of nitrogen. phosphorus, Pholosynthale pigments were a/so significantly increased after 60 days or planting. In these respect the triple inoculation showed superiority than single or duall inoculation. Saparate virus infection. signiflcandy reduced all these parameters. On th other hand a clear recovery was obtained in all nitrogen fixation parameters. as we I as in grain yield and its total N contents of disease plant due 10 application 0 mixture of biofertillzers . The seed yield and its N concentration (N%) of diseased plants was Significantly enhanced by triple inocclauon . The percentage of improvement reached to 137. 27 % and 35.7 % respectively. | ||||
