A collaborative research project between the University of Saskatchewan, the Saskatchewan Wheat Pool, MicroBio RhizoGen Corp. and Westco. Fertilizers Ltd. was initiated in 1994 to identify and develop effective rhizobial inoculants for chickpea and bean, grown in Saskatchewan. A number of chickpea and bean Rhizobium strains were identified as having excellent potential as legume inoculants. In particular, chickpea Rhizobium strain BCF32 and bean Rhizobium strain MBW31 are well suited to Saskatchewan conditions. Bean was particularly responsive to inoculants formulated as granular soil implants.
