- Observation Nitrogen fixation was undetectable in 86 of 100 genotypes at Tamworth.
- Observation Nitrogen fixation was undetectable in 51 of 62 genotypes at Currabubula.
- Observation Six genotypes fixed 10–19% of plant nitrogen versus zero in most check combinations.
- Observation Five further genotypes yielded up to 0.20 t/ha or 14% above checks.
- Intervention effect Iron increased nodulation at flowering by as much as 300%.
- Intervention effect Iron effects on nodulation nearly disappeared by early pod fill.
- Intervention effect Iron did not change Pfix values.
- Intervention effect Shoot dry matter rose with iron rate, especially with nitrogen.
- Intervention effect Iron responses were reduced without nitrogen.
- Intervention effect CB1024 inoculation outyielded CB756 by 1.0 t/ha at Fe0.
- Intervention effect CB1024 inoculation outyielded CB756 by 0.66 t/ha at Fe16.0.
- Observation Genotypes differed significantly in nodulation, fixation, shoot and seed yields without iron, and in iron response.
- Intervention effect High-response genotypes gained an average 0.70 t/ha or 108% seed yield with iron.
- Intervention effect Low-response genotypes gained an average 0.32 t/ha or 25% seed yield with iron.
