Table 3.
Bulk density mean values of predictors obtained from linear mixed model (Eq. 1) for axial and lateral root numbers (NoAx and NoLat, respectively), plant height, leaf and tiller number under low (1.3 g cm-3), moderate (1.45 g cm-3), and high (1.6 g cm-3) soil bulk density 1, 2, and 3 weeks after emergence (WAE); values are based on 4 replications of 14 varieties and root numbers represent back-transformed values.
