Fig. 2. The presumed balance of N remaining after harvest of HGM 100 pearl millet as determined by the difference in N fertilizer applied and N harvested in grain among five different environments; Crowley (C), Bossier City (BC), and Winnsboro (W) in 1998 and/or 1999. Negative values at 0 applied N represent nonfertilizer N removed from soil. Error bars represent ±1 SE. All regression equations were significant to P < 0.05 and coefficients of determination were >0.90.
