Figure 2

Grain yield of different oat varieties with different nitrogen applications. Note: Different lowercase letters for the same variety indicate that the difference between different nitrogen fertilizer levels of the same variety is significant at the p < 0.05 level; * indicates that the difference is significant at the 0.05 level; ** indicates that the difference is significant at the 0.01 level; *** indicates that the difference is significant at the 0.001 level; and ns indicates that the difference is not significant. The same is true for the following Figure 4, Figure 5 and Figure 6.
