Abstract
Synopsis Near maximum yields resulted where 80 pounds N per acre were applied, but carryover was measurable only where 160 pounds were used. In nonleguminous plants, percent N increased with N rates during the vegetative stage, but at maturity it was less where 40 pounds N were applied than in the control. N uptake increased with N rate during winter, but uptake on unfertilized plots during the spring approximated that on plots receiving 40 pounds of N.
