Yield and Chemical Composition of Sudangrass and Forage Sorghum Under Three Systems of Summer Management for Late Fall in Situ Utilization1

Synopsis After‐frost sampling of the aftermaths of forage sorghum and sudangrass from 3 summer cuts, 1 summer cut, and no summer cuts showed no significant change in dry matter yield or percent crude protein. A significant linear increase in percent crude fiber within managements was noted; concentrations of prussic acid decreased sharply. When stockpiled, mature forage sorghum resulted in lower percent crude fiber than immature stages and appreciably lower than comparable growth stages of sudangrass.
