- Intervention effect Removing herbaceous competition increased four-year walnut diameter growth by 153%.
- Intervention effect Removing herbaceous competition increased four-year walnut height growth by 222%.
- Association Nitrogen response did not scale with fertilizer dose.
- Intervention effect Fertilization did not improve growth significantly beyond weed control alone.
- Intervention effect All treatments raised walnut leaf nitrogen content substantially.
- Observation Treated plots retained higher foliar nitrogen than controls four years after treatment.
- Mechanism The authors identify nitrogen competition from broadleaf weeds and grasses as a major cause of walnut growth stagnation.
