Intervention effect Near maximum yields occurred at 80 pounds N per acre.
Association Nonleguminous plant nitrogen percentage increased with nitrogen rate in the vegetative stage.
Intervention effect At maturity, nitrogen percentage at 40 pounds N was lower than the control.
Association Nitrogen uptake increased with nitrogen rate during winter.
Observation Spring nitrogen uptake on unfertilized plots approximated uptake at 40 pounds N.
