Relationship in the southern (), central (x), and northern () zones between planting day of year and whole-plant (a) dry matter yield, (b) crude protein (CP) concentration, (c) acid detergent fiber (ADF) concentration, (d) neutral detergent fiber (NDF) concentration, (e) in vitro true digestibility (IVTD) concentration, and (f) cell wall digestibility concentration. Data are averaged across environment, hybrid, and replication (each point is the mean of 192 points). Equations and coefficients of determination (R2) for Fig. 1. are reported in Table 4.

Relationship in the southern (), central (x), and northern () zones between planting day of year and stover (a) dry matter yield, (b) crude protein (CP) concentration, (c) acid detergent fiber (ADF) concentration, (d) neutral detergent fiber (NDF) concentration, (e) in vitro true digestibility (IVTD) concentration, and (f) ear/stover ratio. Data are averaged across environment, hybrid, and replication (each point is the mean of 192 points). Equations and coefficients of determination (R2) for Fig. 3 are reported in Table 5.
