- Intervention effect NPK gave the highest significant maize yields compared with treatments omitting a nutrient.
- Intervention effect NPK increased maize grain yield by over 150% versus control across three seasons.
- Intervention effect NP increased maize grain yield by over 150% versus control across three seasons.
- Intervention effect NK increased maize grain yield by over 150% versus control across three seasons.
- Intervention effect Omitting N caused the largest grain losses, 2.06, 2.40 and 2.42 t ha-1 across the three seasons.
- Intervention effect Omitting P caused grain losses of 0.8, 0.59 and 0.43 t ha-1 across the three seasons.
- Intervention effect Conservation agriculture significantly increased soil P over three seasons.
- Intervention effect Soil K was significantly higher under conservation agriculture than conventional agriculture.
- Intervention effect Minimum tillage raised benefit to cost ratio by 3% in LR2015 versus conventional tillage.
- Intervention effect Minimum tillage raised benefit to cost ratio by 5% in SR2015 versus conventional tillage.
- Intervention effect Conventional tillage raised total variable cost by 4% in LR2015 versus minimum tillage.
- Intervention effect Conventional tillage raised total variable cost by 2% in SR2015 versus minimum tillage.
- Observation Treatments with N and conservation agriculture were most profitable.
- Recommendation The authors recommend conservation agriculture with NPK to increase maize yield and investment returns.
