Other claims from this paper (11)
- Observation Aurora averaged 50% plant nitrogen from the atmosphere.
- Observation Kentwood averaged 32% plant nitrogen from the atmosphere.
- Observation The percentage of plant nitrogen from atmosphere did not vary across years.
- Association Yield and actual nitrogen fixed varied with soil nitrogen levels.
- Observation Aurora averaged 70 kg N ha −1 fixed.
- Observation Kentwood averaged 37 kg N ha −1 fixed.
- Observation Some strains fixed over 100 kg N ha −1 in Aurora.
- Intervention effect Some strains gave Aurora dry matter and nitrogen yields above uninoculated fertilized treatments.
- Observation Several CIAT strains and commercial Nitragin were highly efficient nitrogen fixers with Aurora.
- Observation Several CIAT strains and commercial Nitragin were highly efficient nitrogen fixers with Kentwood.
- Recommendation Certain bean cultivars can meet field yield potential without fertilizer nitrogen while fixing nitrogen.
