Maturity stages around harvest (MS1: Zadoks code 83; MS2: code 87; MS3: code 91).
Calculated from the remaining materials for each treatment (g), using respective starting OM (week 0) for each maturity stage.
Values with different superscripts within a column are significantly (P < 0.05) different.
DM, dry matter; OM, organic matter; Cell, cellulose; Hcell, hemicellulose; ADL, acid detergent lignin; Sugar, free reducing sugar from ethanol‐extract of wheat straw; CP, crude protein (N × 6.25); NI, unaccounted OM; RMSE, root mean square error.
