What was the primary agriculture product in Oklahoma during the early 20th century?

Wheat was the primary agricultural product in Oklahoma during the early 20th century for several reasons. The state's climate and soil conditions were particularly well-suited for wheat farming, making it one of the most productive wheat-growing regions in the United States. As a result of these favorable conditions, wheat became a staple crop, especially during the years following statehood in 1907, when farmers began to fully utilize the fertile land available to them.

The importance of wheat was further heightened during World War I, when there was a significant demand for food supplies, leading to increased production. Additionally, agricultural practices in Oklahoma evolved to focus on wheat cultivation due to its profitability and the establishment of cooperative marketing and distribution systems. While other crops such as corn, cotton, and soybeans were grown, none matched the widespread cultivation and significance of wheat during this period.
