Other claims from this paper (4)
- Intervention effect Maximum technical yield was 38.5 t ha−1 at 380 kg ha−1 P2O5.
- Intervention effect Phosphate response decreased or ceased above 13 mg dm−3 available P, at 37.7 t ha−1 marketable yield.
- Association Higher P2O5 rates correlated negatively with shoot Fe, B, Cu, and Zn relative to P.
- Association Higher P2O5 rates correlated negatively with P versus K in shoots, storage roots, and whole plants.
