- Intervention effect Groundnut kernel yield reached a maximum of 1923 kg/ha at RDF plus 100 kg K2O/ha.
- Intervention effect Groundnut test weight reached a maximum of 44.5 g at RDF plus 100 kg K2O/ha.
- Intervention effect Groundnut total nitrogen uptake reached a maximum of 84. 3 kg/ha under the 100 kg K2O/ha treatment.
- Intervention effect Groundnut phosphorus uptake reached a maximum of 24.7 kg/ha under the 100 kg K2O/ha treatment.
- Intervention effect Groundnut potassium uptake reached a maximum of 103.6 kg/ha under the 100 kg K2O/ha treatment.
- Observation The absolute control had the lowest groundnut growth, yield and nutrient uptake.
- Observation Postharvest soil available nitrogen reached 179.2 kg/ha under RDF (NP alone).
- Observation Postharvest soil phosphorus content reached 26.7 kg/ha under RDF (NP alone).
- Observation Postharvest soil potassium content reached 275.2 kg/ha under RDF plus 175 kg K2O/ha.
- Intervention effect Excess potassium application decreased groundnut growth, yield attributes and nutrient uptake.
- Recommendation The authors conclude that 100 kg K2O/ha improves groundnut yield and nutrient uptake.
