Other claims from this paper (8)
- Intervention effect Higher plant density increased root length density.
- Intervention effect Reduced N input decreased root length density in the 0–1.2 m, 0–0.4 m and 0.4–0.8 m soil layers.
- Intervention effect Reduced N input increased root length density in the 0.8–1.2 m layer.
- Intervention effect Combined higher plant density and lower N input reduced N uptake.
- Intervention effect Combined higher plant density and lower N input gave a lower nitrogen nutrition index.
- Intervention effect Combined higher plant density and lower N input left grain yield unchanged.
- Intervention effect Combined higher plant density and lower N input improved N use efficiency.
- Recommendation Maintaining a high wheat yield with reduced N input by increasing plant density is possible and sustainable.
