Legumes are an important source of protein in food and fodder, besides they are useful as forecrop. Many studies have been conducted on the efficiency of different Rhizobium sp. strains or Glomus sp. separately, but very little and contradictory information is available on the symbiosis of Rhizobia – Glomus – legume tripartite. The vegetation pot experiment was carried out to explain Rhizobium legumnosarum and Glomus sp. impact on vegetative parameters, chlorophyll content and water retention capacity of faba beans (Vicia faba var. major L.). The obtained results showed that shoot/root ratio increased in comparison with the control in all treatments. The treatment with mycorrhiza fungi improved water retention capacity in the broad bean leaves, increased the ratio between chlorophyll a and b, and increased the weight of root nodules. Rhizobia strain No. 23 was more effective in comparison with No. 407. The combination of Glomus sp. and R. leguminosarum promoted the increase of faba bean biomass.
