Values are based on hand fractionation of composite chopped stover bale samples collected during the Finish trial. Samples were composited over 4 wk and analyzed. Results are based on three composite samples.

Fraction consisting of leaf and husk.

See Table 2 footnotes for definition of this and subsequent abbreviations.

Not determined due to insufficient sample replicates.

Within fraction, means in a rows without common superscripts differ at P ≤ 0.05.
