The effect of four bacterial and six fungal species on nodulation and growth of Vicia
faba cv. Giza 3 inoculated with Rhizobium leguminosarum biovar viceae strain RCR
1001 were assessed in a pot experiment. Bacillus cereus, Pseudomonasfluorescens,
Aspergillus niger and ,4. quadriliniatus either alive cells or sterile filtrate
significantly promoted nodulation, growth and nitrogen accumulation. Heat-killed
cells had no effect.
