Other claims from this paper (8)

Intervention effect Alkalinity reduced leaf Fe status.
Observation Fe-EDDHA improved chlorophyll traits, leaf Fe and seed Fe more efficiently in tolerant cultivars.
Observation Fe-EDDHA improved seed protein and yield components more efficiently in tolerant cultivars.
Observation Sensitive cultivars required higher Fe doses for partial recovery.
Observation Fe deficiency increased seed phytate and phosphorus.
Observation Fe resupply reduced phytate in most cultivars.
Observation FRO/IRT1-like, OPT3 and FER expression indicated genotype-dependent Fe handling.
Recommendation Authors favor genotype selection combined with Fe fertilization for biofortification.
