- Intervention effect Nitrogen input significantly increased grain yield.
- Intervention effect Nitrogen input significantly reduced nitrogen-use efficiency.
- Observation The hybrids did not significantly differ in yield at high nitrogen.
- Observation The hybrids did not significantly differ in NUE at high nitrogen.
- Observation At low nitrogen ZD958 had 16.2% higher grain yield than T391.
- Observation At low nitrogen ZD958 had 15.6% higher NUE than T391.
- Observation ZD958 had 5.0% greater pre-silking dry matter than T391.
- Observation ZD958 had 7.9% greater post-silking dry matter than T391.
- Observation ZD958 had 11.6% greater pre-silking nitrogen accumulation.
- Observation ZD958 had 32.7% greater post-silking nitrogen accumulation.
- Observation ZD958 reallocated 45.6% more dry matter than T391.
- Observation ZD958 reallocated 17.5% more nitrogen than T391.
- Observation ZD958 grain nitrogen needed 15.5–38.1% remobilization from vegetative organs.
- Observation More grain nitrogen came from stem than leaves.
- Observation Middle leaves and lower stems tended to reallocate more nitrogen to grain.
- Association Lower stem nitrogen reallocation was significantly related to grain yield.
- Recommendation The authors propose high dry matter and nitrogen accumulation and remobilization as breeding traits under low nitrogen.
