Other claims from this paper (7)
- Intervention effect Under maximum N stress in the 8- to 12-leaf phase, Pioneer 3902 had higher N uptake per unit ground area than Pride 5.
- Intervention effect At high N, Pride 5 had higher N uptake per unit ground area than Pioneer 3902.
- Intervention effect Pioneer 3902 had higher N uptake per unit root weight than Pride 5 under medium and low N supply.
- Association Leaf N per unit leaf area was higher in the new hybrid than in the old hybrid.
- Association The new hybrid Pioneer 3902 maintained greater rates of leaf photosynthesis per unit leaf N regardless of N supply.
- Association Higher N-use efficiency of Pioneer 3902 under low N supply is associated with higher N uptake.
- Association Higher N-use efficiency of Pioneer 3902 under low N supply is associated with a higher leaf N per unit leaf area.
