Symbiotic efficiency of indigenous common bean rhizobia isolated from Northwestern Croatia

The strains of nodule bacteria differ greatly in their symbiotic properties and efficiency nitrogen fixation therefore, the selection highly effective is great importance when attempting to achieve a successful pre-sowing inoculation common bean. aim this study was determine nodulation ability indigenous rhizobial evaluate compatibility efficacy with two bean cultivars. A two-factorial pot experiment (12 cultivars) set up greenhouse. In full blossom phase, dry biomass, shoot weight N content determined. research revealed significant differences depending on strain reference examined cultivars also observed. cultivar Tresnjevac significantly better than Slavonski zeleni all measured parameters. results that considerable efficiency. highest biomass determined HO12 applied, MB1 DE7. application DE7 shoot. indicate these nodulating are characterized by could be used for after testing field scale experiment.
