- Observation Maximum agronomic efficiency occurred at 150 kg ha-1 K2O and 116 Mg ha-1 production.
- Intervention effect K doses above 200 kg ha-1 decreased productivity through soil salinity.
- Observation The soil K critical level was 0.18 cmolc dm-3.
- Observation The plant K critical level was 9.53 g kg-1.
- Association Surface salinity at 1.38 dS m-1 reduced productivity.
- Association Subsurface salinity at 1.19 dS m-1 reduced productivity.
