Legumes are important crop all over the world due to their protein content, possibility to fix atmosphere nitrogen and provide sustainable soil quality. Experiments were carried out to assess the role of symbiotic relationships on some plant characteristics (chlorophylls content, plant biomass, nodule weight, dehydrogenases activity, yield, protein content in plants and seeds). Results showed that the use of rhizobia may contribute to protein accumulation in seed, but certain strains effectiveness depends on soil properties and plant varieties. Plant and rhizobia interaction efficiency can be described with dehydrogenase activity. In order to obtain a more stable symbiotic nitrogen fixation effect, it is necessary to combine different rhizobia strains.
