How effective are new inoculant formulations in nodulating grain legumes? locations
Aims

Since these inoculants have not had widespread use, the aim in this study was to test these new delivery systems and their effect on nodulating grain legumes in a range of Australian soils.

Key messages
  • Inoculation with effective formulations significantly improved nodulation, herbage and yield. 
  • Sterile peat slurry innoculant produced more nodules on faba beans than all other rhizobial products; freeze dried rhizobia applied to seed and peat applied as liquid inoculant produced greater nodules than granular inoculants. 
  • inoculation with peat slurry, peat applied as a liquid, and freeze dried inoculants significantly improved herbage and yield compared with uninoculated treatments. Yield was also improved following application of bentonite granules.
