- Intervention effect Drip fertigation increased grain yield by 15.4–20.8% versus conventional management.
- Association Yield responded quadratically to planting density under both regimes.
- Intervention effect Drip fertigation raised optimal planting density to 456–487 seeds m−2 versus 377–378 under conventional management.
- Intervention effect Drip fertigation sustained near-maximum yield over a broader density range.
- Intervention effect Drip fertigation increased productive stem percentage and grains per ear.
- Intervention effect Drip fertigation increased grain number per square metre.
- Intervention effect Drip fertigation increased post-anthesis dry matter production by 15.5–17.6%.
- Association Post-anthesis dry matter production was strongly associated with yield.
- Association More density treatments under DF had both high grain number and high post-anthesis dry matter accumulation.
- Intervention effect Drip fertigation increased nitrogen nutrition index at anthesis.
- Intervention effect Drip fertigation increased post-anthesis nitrogen uptake by 47.7–49.5%.
- Intervention effect Drip fertigation raised total nitrogen uptake at maturity and grain nitrogen accumulation.
- Intervention effect Drip fertigation improved fertilizer nitrogen recovery efficiency by 33.9–42.3%.
- Intervention effect Drip fertigation improved agronomic efficiency by 26.7–30.9%.
