Other claims from this paper (11)
- Observation Plant N accumulation rates were greatest between 12 leaf and silking in 1979.
- Observation Plant FN accumulation rates were greatest between 12 leaf and silking in 1979.
- Observation With N applied at 16 leaf, maximum accumulation occurred in early grain fill.
- Observation Application time had more pronounced effects on N accumulation in 1980.
- Observation Residual fertilizer nitrogen from 1979 accumulated in aboveground tissue in 1980.
- Observation Residual FN uptake appeared greater than new FN uptake in heavily fertilized crops.
- Observation Residual FN uptake appeared greater than new FN uptake in late planted crops.
- Association Later N application delayed maximum accumulation.
- Intervention effect Early N deprivation reduced yield only when uptake stopped in early grain fill.
- Intervention effect Delayed planting reduced FN recovery at both fertilization levels.
- Intervention effect Low N applied late maximized relative grain FN recovery.
