Other claims from this paper (11)
- Intervention effect Urea and ammonium nitrate had no effect on iron amino acid chelate effectiveness.
- Intervention effect At 1000 ppm nitrogen, urea and ammonium nitrate decreased iron EDTA effectiveness.
- Intervention effect Iron amino acid chelate increased dry matter yield on average.
- Intervention effect Iron sulfate did not increase dry matter yield.
- Intervention effect Iron EDTA did not increase dry matter yield.
- Intervention effect Nitrogen alone did not significantly affect dry matter yield.
- Intervention effect Iron amino acid chelate gave higher leaf iron concentration than the other two iron sources.
- Intervention effect Chelated iron sources led to more iron translocation to roots than iron sulfate.
- Intervention effect Foliar iron amino acid chelate increased plant manganese concentration.
- Intervention effect Adding urea and ammonium nitrate to iron solution increased manganese uptake.
- Mechanism Authors suggested manganese accumulation from foliar iron may contribute to higher dry matter yield.
