Regression model for mean nitrate content in cuphea tissue (A) at six N fertility treatments averaged across three phenological stages (vegetative, bloom, and harvest) and three environments (Casselton, ND, 2005, and Glyndon,MN 2005 and 2006) (Env) for Exp. 1, and averaged across four N fertility treatments for Morris, MN 2005 and 2006 for Exp. 2 (P 0.05) (B) at three phenological stages (vegetative, bloom, and harvest) averaged across six N fertility and three environments for Exp. 1, and averaged across four N fertility for Morris 2005 and 2006 in Exp. 2.
