Reduction of NN compared to EE (%) | −38.15 | −41.53 | −33.44 |
1) EE, efficient-efficient varieties; NN, nonefficient-nonefficient varieties.
2) N1 and N3 indicate 57.5 kg N ha-1 of soil (normal-N) and 173 kg N ha-1 of soil (high-N), respectively.
Different lowercase letters in Mean indicate significant differences at P < 0.5 according to Student t-Test between N1 and N3.
Different uppercase letters indicate significant differences at P < 0.5 according to Student t-Test between EE and NN.
Different lowercase letters in each variety indicate significant differences at P < 0.5 according to Tukey HSD test among variety under N1 and N3 in each group.
*, **, and *** means significant differences at P < 0.5, P < 0.01, and P < 0.001, respectively, and ns means not significant according to Two-ways ANOVA.
