Other claims from this paper (11)
- Intervention effect Calcium chloride spraying reduced the number of symptomatic leaves per corn plant.
- Intervention effect Calcium chloride spraying suppressed development of leaf serration.
- Association Leaf serration did not significantly affect corn shoot dry matter yield at the yellow-ripe stage.
- Intervention effect Calcium spraying did not affect corn yield.
- Association Symptomatic leaf number increased logarithmically with soil exchangeable potassium content.
- Mechanism Excessive soil potassium lowered corn plant calcium concentration.
- Observation Corn varieties differed significantly in symptom appearance.
- Association The variety with the highest calcium concentration had the most symptomatic leaves.
- Method / resource Varieties with low and high calcium concentrations had different regression equations relating soil potassium to symptomatic leaf number.
- Method / resource The equations estimated soil exchangeable potassium from symptomatic leaf number after silking.
- Recommendation The authors recommend reducing potassium input when corn develops leaf serration.
