- Association Mulch, density, and fertilizer interacted significantly for grain yield and kernel number.
- Association These three factors interacted significantly for N uptake, translocation, and translocation efficiency.
- Observation At silking, total plant N uptake ranged from 79 to 149 kg N ha − 1 without mulch.
- Observation At silking, total plant N uptake ranged from 76 to 178 kg N ha − 1 with mulch.
- Observation N uptake at silking ranked leaf above grain, stem, and cob.
- Observation N translocation was 59.4% higher in leaves than stems.
- Observation N translocation was 88.7% higher in leaves than ears.
- Observation Vegetative organ N translocation efficiency decreased from leaf to stem to cob.
- Intervention effect Mulch, density, and N rate significantly improved grain yield and nitrogen use efficiency.
- Intervention effect The management factors significantly improved N uptake, translocation, and translocation efficiency.
