Observation Carryover was measurable only at 160 pounds N.
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.
