What does the term "biannual" refer to in agricultural practices?

The term "biannual" in agricultural practices specifically refers to something occurring every other year. This distinction is crucial in planning for crop rotations, budgeting for resources, and understanding the life cycle of specific plants. For instance, if a crop is biannual, it will be planted one year and then again the following year, but not in the intervening years. This can impact soil health, pest management, and yield expectations as farmers plan their growing seasons.

In contrast, options that imply different planting frequencies, such as annual or once (which would refer to the crop being planted just one time) or twice a year, do not accurately represent the meaning of "biannual." Understanding these terms is essential for effective agricultural planning and management.
