Other claims from this paper (13)
- Association Potassium had a greater influence on grain yield than phosphorus level.
- Intervention effect Potassium application increased yield-related parameters.
- Intervention effect Phosphorus affected leaf phosphorus and sodium content and Na:K and Ca:Na ratios.
- Intervention effect Potassium significantly affected leaf sodium, potassium, magnesium, and Na:K ratio.
- Intervention effect Phosphorus and potassium interactions did not affect leaf chemical composition except magnesium.
- Intervention effect Phosphorus increased maize leaf phosphorus relative to control.
- Intervention effect Potassium decreased sodium and Na:K ratio.
- Association Grain yield was positively related to leaf phosphorus in phosphorus-treated soils, with R2 = 0.67.
- Association Dry matter yield was positively related to leaf phosphorus in phosphorus-treated soils, with R2 = 0.76.
- Intervention effect Calcium content and Ca:K and Ca:P ratios were not significantly affected by potassium and phosphorus.
- Intervention effect Extractable soil phosphorus increased after phosphorus treatments.
- Intervention effect Potassium significantly decreased soil Na:K ratios.
- Association Soil Na:K ratio was negatively correlated with soil potassium, with R2 = 0.91.
