e0“we investigated how tillage (NT, no-tillage; CT, conventional tillage) and N fertilization affected the small-scale variation in NUE and winter wheat performance (grain yield, Gw; grain protein concentration, GPC)”
e1“At rates < 150 kg N ha−1, NT was not competitive with CT in terms of Gw and NUE”

Other claims from this paper (8)
- Association Grain yield and aboveground plant N were not correlated with soil mineral N (Nmin) before N fertilizer application.
- Association Grain yield and grain protein concentration increased with increasing N rates.
- Association NUE decreased slightly with increasing N rates in both NT and CT.
- Association Small-scale variability of Gw, GPC and NUE decreased with increasing N fertilization rates under both tillage systems.
- Association Small-scale variability of N supply decreased with increasing N fertilization rates.
- Recommendation Site-specific N fertilization was not justified for these small fields.
- Association Stony within-plot positions were not responsive to N rates above 50 kg N ha-1.
- Association No-tillage usually led to larger spatial heterogeneity of Nmin, grain yield and NUE.
