Weather events or unusual circumstances will sometimes lead to the decision to produce an "emergency" forage crop. The forage crop chosen often is a warm-season annual grass harvested one to three times during the growing season. The choice of crop species depends primarily on how the crop will be stored or used (hay, silage, or grazed), the type of animal being fed, and the yield expectations.
