The effect of Rhizobia inoculum rates on faba bean yield locations
Aims

To investigate the nodulation and yield response of Faba beans to higher rates of rhizobia inoculation.

Key messages

Rhizobium inoculation improved faba bean yields by 9-30% above uninoculated plants. Higher rates of rhizobium inoculum show a trend to further increase yield though this was not significant. Rhizobium inoculation should be considered as cheap insurance against conditions not favourable to nitrogen supply, particularly during winter.
