Other claims from this paper (13)
- Intervention effect Coated Fe EDTA raised leaf iron content about 10% versus untreated plants.
- Intervention effect Coated Fe EDTA raised chlorophyll content about 71% versus untreated plants.
- Intervention effect Coated Fe EDTA improved growth and dry weight.
- Intervention effect Coated Fe EDTA increased iron uptake in leaves and shoots.
- Intervention effect Organic acids decreased about 11%.
- Observation Chlorosis symptoms did not appear in treated and untreated plants.
- Observation FeSO4 treatment led to chlorosis symptoms after application only in the first year.
- Intervention effect Combined Fe EDTA and FeSO4 increased iron content, dry weight and iron uptake.
- Intervention effect Combined Fe EDTA and FeSO4 slightly decreased organic acids.
- Intervention effect Singly applied coated Fe EDTA gave higher measures than the combination except for iron content.
- Intervention effect Coated Fe EDTA raised chlorophyll content in chlorotic field plants.
- Observation At the second location chlorophyll and iron content remained unchanged where chlorosis was absent.
- Recommendation The authors recommend coated Fe EDTA as fertilizer when water is sufficient.
