Which of the following is NOT considered a small grain?

Rice is not considered a small grain in the context of crop classifications. Small grains refer specifically to cereal crops that are generally cultivated for their seeds or grain and include crops like wheat, barley, and oats. These grains are often characterized by their ability to grow in shorter growing seasons and their smaller seed size compared to other grains.

Rice, on the other hand, is classified distinctly as a staple food crop, primarily cultivated in flooded fields and typically requiring a longer growing season. Its agricultural practices and cultivation requirements set it apart from traditional small grains, which are more drought resistant and suited for a wider range of soil types and climates. As such, rice's unique cultivation methods and growth conditions differentiate it from the commonly recognized small grains.
