FIGURE 1

Root dry weight (RDW) (A,B) and root length density (RLD) (C,D) in the 0–60 cm soil layer for SJZ8 (black) and KN92 (red) at anthesis stage in 2010 and 2011. Values are means ± SE of four replicates. Within each cultivar, different lowercase letters indicate significant difference between P application levels (Turkey test, P < 0.05); ns and indicate no significant difference and significant difference, respectively, between SJZ8 and KN92 at the same P application level (Student T-test, P < 0.05).
