Abstract :

A field experiment was conducted for two consecutive seasons to examine the effect of inoculation by different Rhizobium and phosphate solubilizing bacteria strains and their interaction on symbiotic properties and yield of faba bean, and to compare between the effects of chemical fertilizers and biofertilizers. Both Rhizobium and phosphate solubilizing bacteria significantly increased yield and symbiotic properties (nodulation, nodules and shoots dry weight, and plant nitrogen and phosphorus content) of faba bean plants. A synergetic effect was observed when the two types of microorganisms were combined. Comparable increments in yield were obtained resulting from either microbial fertilizers (nitrogen fixing and/or phosphate solubilizing bacteria) or chemical fertilizers (nitrogen and phosphorus fertilizers). Key words: Rhizobium, Bacillus, Vicia faba, nitrogen fixation, phosphorus solubilizing bacteria.
