Which of the following is included in small grains?

The inclusion of wheat in the category of small grains is correct because wheat is one of the most significant small grain crops grown in Kansas and other regions. Small grains typically refer to cereal crops that are harvested for their seeds and often include grains that have a short growing season. Wheat, along with oats and barley, consists of these short-season crops which are significant for the agricultural economy.

Oats and barley are also part of the small grains category, as they fit the typical characteristics of these crops. However, corn is not included in the small grains classification because it is a warm-season crop that grows on larger stalks and requires a longer growing season compared to the smaller grains. The distinction is crucial to understanding crop classification and their respective farming practices.
