FIGURE 5.
Root length density in the topsoil and subsoil layers for CW134, CH58 and CH1 in the field trial at (A,B) stem elongation and (C,D) anthesis under (A,C) rainfed (RF) and (B,D) irrigated (IR) conditions. Different letters in the same growth period imply a significant difference at P < 0.05. Horizontal bars represent + one standard error of the mean (n = 3).
