Other claims from this paper (10)
- Intervention effect Soil sulphur and gypsum significantly increased groundnut N, K and S concentrations.
- Intervention effect Sulphur treatments significantly reduced groundnut leaf sap pH and P and Fe concentrations.
- Intervention effect Foliar Fe-EDDHA increased groundnut chlorophyll a and b.
- Intervention effect Foliar Fe-EDDHA marginally increased groundnut N concentration.
- Intervention effect Foliar Fe-EDDHA left groundnut K and S concentrations unaffected.
- Intervention effect Foliar Fe-EDDHA significantly reduced groundnut P and Fe concentrations.
- Intervention effect Foliar Fe-EDDHA did not affect groundnut leaf sap pH.
- Mechanism The authors suggested impaired iron translocation and inactivation as the probable cause of chlorosis despite high tissue iron.
- Mechanism The authors interpreted sulphur as sustaining physiologically active iron for chlorophyll synthesis.
- Mechanism The authors suggested high plant P as a reason for reduced Fe-EDDHA efficacy.
