Verbatim
e0“the number of functional nodules and their leghaemoglobin content were more in the cases of plants treated with Fe‐EDDHA and Fe‐EDTA (@ 5 mg kg‐1 soil) than in the FeSO4 treated ones.”

Other claims from this paper (9)
- Intervention effect At 5 to 10 mg kg‐1 soil, iron stimulated functional nodules.
- Intervention effect At 5 to 10 mg kg‐1 soil, iron increased plant dry weights.
- Intervention effect Fe‐EDDHA at 5 mg kg‐1 soil produced more functional nodules than FeSO4.
- Intervention effect Fe‐EDTA at 5 mg kg‐1 soil produced more functional nodules than FeSO4.
- Intervention effect Fe‐EDTA at 5 mg kg‐1 soil produced greater nodule leghaemoglobin content than FeSO4.
- Intervention effect A double dose of FeSO4 yielded similar nodule initiation.
- Intervention effect Iron treatments increased in vivo nitrogen fixation over untreated controls in pot and field experiments.
- Observation Fe‐EDDHA was ranked most effective for functional nodules, then Fe‐EDTA and FeSO4.
- Recommendation The authors suggest growers use whichever iron source is economical.
