In agriculture, continuous harvest is the availability of a crop over an extended period during the growing season.
Each crop has a harvest window during which it is ready for picking.
Some are harvested by removing the whole plant, for example, cutting a head of lettuce.
Others can be picked over varying periods: peas and corn may have a window of two weeks, cucumbers six or eight, tomatoes produce until the end of the season.
In this way, with effective timing, a new planting or variety of a crop is always coming into maturity as a previous one finishes.
