Other claims from this paper (10)
- Intervention effect No-tillage mode had no significant effect on spring maize yield compared with conventional tillage.
- Observation The proper N rate for spring maize was 190～209, 192～212 and 193～216 kg/hm2 for no-tillage 1, no-tillage 2 and conventional tillage.
- Association Partial factor productivity from applied N (PFPN) of spring maize gradually decreased as N application rate increased.
- Association Agronomic efficiency of applied N (AEN) and apparent recovery efficiency of applied N (REN) of spring maize were highest at an N rate of 150 kg/hm2.
- Association Agronomic efficiency of applied N (AEN) and apparent recovery efficiency of applied N (REN) of spring maize significantly decreased when N application rate was more than 225 kg/hm2.
- Observation PFPN of spring maize was 48.3～70.2, 48.0～70.4 and 49.0～68.5 kg/kg.
- Observation AEN of spring maize was 15.2～20.5, 15.2～21.1 and 16.4～18.6 kg/kg.
- Observation REN of spring maize was 32.5%～44.0%, 32.5%～45.2% and 35.1%～39.0%.
- Intervention effect No-tillage mode could reduce the cost of soil tillage of spring maize compared with conventional tillage.
- Association High N application rate could not increase spring maize yield.
