Title: Alleviation of salinity and viral disease effect on faba bean by inoculation and nitrogen fixation
Author: Osman, Awad G.; Elsheikh, Elsiddig A.E.
Abstract: Six faba bean cultivars were screened for nodulation with four strains of Rhizobium leguminosarum bv, vieae. Salts and broad bean mottle virus (BBMV) were added to faba bean cultivar Agabat which was either uninoculated, or inoculated with Rhizobium leguminosar bv. vieae, strain SVf01 (local) or strain TAL 1397 (introduced), in a factorial pot experiment. Salinity (5.0 dSm¹). virus infection and their combination significantly decreased shoot and root dry weights, nodules number, nodules dry weight, number of flowers and pods per plant, total plant nitrogen and nitrogen fixation. Rhizobium inoculation significantly increased all parameters above, compared to uninoculated control treatments. The local and the introduced strains increased nitrogen fixation by 90% and 121%, respectively, under normal conditions. The results indicate that these Rhizobium strains are effectively fixing nitrogen in normal, saline and/or virus infected faba bean plants.
