- Association Abundance of water and limited nitrogen availability were associated with low grain N concentrations in maize.
- Association Abundance of water and limited nitrogen availability were associated with enriched leaf δ13C in maize.
- Association Abundance of water and limited nitrogen availability were associated with reduced maize grain yield.
- Association Maize near frequently pruned grass barriers had elevated leaf δ13C values.
- Mechanism Yield decline in grass-barrier rows is attributed mainly to nitrogen competition.
- Association Maize from rows next to grass barriers had enriched δ15N values, indicating reliance on soil N.
- Intervention effect Vigorous cover crop growth under minimum tillage resulted in maize yield decline due to N competition.
- Intervention effect Relay-cropped legumes under minimum tillage gave a maize yield similar to the control.
- Intervention effect Relay-cropped legumes gave leaf N concentration, δ13C and δ15N similar to the control in maize.
