Values of each variable are means of four replicates. For each variable under each maize cultivar, bold values indicate significant differences between years at p < 0.05. For ANOVA analyses, *, **, and *** show significant N fertilization (N), maize cultivar (C), and their interaction effects at p < 0.05, p < 0.01, and p < 0.001, ns—not significant, respectively.
