  		Fig. 2. The effect of N rate during three growing seasons on (a) N concentration in grain and stover and (b) biomass yield. All linear functions are significant except for grain N concentration in 1996 and biomass yield in 1998. All quadratic functions were significant except for grain N concentration in 1996 and biomass yield in 1998.
