The aim of this trial was to to compare commercial faba bean rhizobia inoculant with new acid tolerant strains from SARDI and the Department of Primary Industries and Regional Development (DPIRD), WA.
New acid tolerant strains of rhizobia show potential to increase faba bean yield on acid soils (pHCaCl2 < 5.2), however, such rhizobia options are still several years from commercialisation. In the short term, using a double rate of Group F inoculant provides a practical way to increase faba bean yields when they are grown on acid soils, which is likely linked to increasing the number of rhizobia surviving at the time of nodulation. In this trial doubling, but not quadrupling, the number of bacteria applied to the seed improved grain yield due to the probable increase in rhizobia bacteria surviving within acid soil conditions.
