Question

which of the following is not a field crop?
wheat
cotton
barley
hay

Explanation:

Field crops are typically grown for food, feed, fiber, or fuel. Wheat, barley, and cotton are commonly classified as field crops. Wheat and barley are cereal grains used for food and animal feed. Cotton is a fiber crop. Hay, on the other hand, is usually considered a forage crop rather than a traditional field crop. Forage crops are primarily grown as animal feed, often in the form of grass or legume mixtures that are cut and stored as hay.

Answer:

Hay
