Other claims from this paper (11)
- Observation Summer maize grain yield ranged from 6.6 to 14.2 t ha−1 and averaged 10.5 t ha−1.
- Observation PFPN ranged from 15.4 to 96.1 kg kg−1 and averaged 49.1 kg kg−1.
- Observation Laoling mean yield gap was 3.6 t ha−1 and PFPN gap 43.3 kg kg−1.
- Observation Xushui mean yield gap was 2.2 t ha−1 and PFPN gap 24.5 kg kg−1.
- Association Yield gap and PFPN gap were positively correlated.
- Association Reducing yield gap 1 t ha−1 could reduce PFPN gap 6.0 kg kg−1.
- Association High yield and PFPN fields had higher plant density than low yield and PFPN fields.
- Association High yield and PFPN fields had lower nitrogen fertilizer rates.
- Association Plant density contributed slightly more to the yield gap than other management practices.
- Mechanism Low PFPN was mainly attributed to excess nitrogen fertilizer.
- Recommendation The authors recommend programs to help farmers adopt optimal management practices.
