Other claims from this paper (19)
- Observation Early-maturing hybrids had lower nitrogen uptake than late-maturing hybrids.
- Observation CRU or SAU achieved nitrogen supply-demand balance in early-maturing hybrids.
- Observation CRU combined with SAU achieved nitrogen supply-demand balance in late-maturing hybrids.
- Intervention effect Compared with urea, CRU and two- or three-stage application increased yield and NUE.
- Intervention effect The same treatments reduced environmental nitrogen loss.
- Intervention effect TC raised DH518 grain yield by 11.1% versus T1.
- Intervention effect T2 raised DH518 grain yield by 9.8% versus T1.
- Intervention effect TC raised DH605 grain yield by 16.4% versus T1.
- Intervention effect T2 raised DH605 grain yield by 15.7% versus T1.
- Intervention effect T3 raised DH605 grain yield by 22.9% versus T1.
- Association DH518 grain yield followed a bilinear trend with post-anthesis N accumulation, total N accumulation, recovery efficiency and NNI.
- Association DH605 yield showed a linear relationship with a rapid increase.
- Intervention effect In DH518 T3, sowing-stage urea had 60.0% higher recovery efficiency than VT topdressing.
- Intervention effect In DH518 T3, V9 topdressing had 62.4% higher recovery efficiency than VT topdressing.
- Intervention effect In DH605 T3, V9 topdressing had 37.7% higher recovery efficiency than sowing-stage urea.
- Intervention effect In DH605 T3, VT topdressing had 37.1% higher recovery efficiency than sowing-stage urea.
- Observation DH518 NNI reached at least 0.988 under T2 and TC.
- Observation DH605 reached optimal nitrogen status only under T3.
- Recommendation The authors recommend three-stage urea or CRU plus later topdressing for mid-late hybrids.
