Other claims from this paper (9)
- Observation Maize grain yield ranged from 6.0 to 11.8 t ha-1 across treatments.
- Intervention effect Anticipating N application at oat desiccation or maize sowing decreased maize grain yield in two of three years.
- Intervention effect S4 promoted a maize yield advantage of 2.2 t ha-1 over S2 and S3 in the rainiest early spring season.
- Intervention effect Applying total N rate before or at sowing decreased the number of kernels per ear in 2000/2001 and 2001/2002.
- Intervention effect Applying total N rate before or at sowing decreased the number of ears per area in 2001/2002.
- Intervention effect Applying total N rate before or at sowing reduced maize grain yield.
- Intervention effect The agronomic efficiency of applied N was always higher in the S4 system than in the S2 and S3 systems.
- Association Short-term N immobilization did not reduce maize grain yield when no N was applied before or at sowing, regardless of tillage.
- Association Maize response to the time and form of splitting N was not affected by the soil tillage system.
