Did you know that Oklahoma is a leading producer of wheat, cattle, pork, and greenhouse and nursery products?
Oklahoma’s diverse landscape – from the Great Plains to the Ozark Mountains – provides ample opportunity for farmers and ranchers to grow a variety of crops and livestock.
Wheat is the state’s top crop. Other important crops include soybeans, cotton, corn, and sorghum. Cattle ranching is also a vital part of Oklahoma agriculture.
The state is home to millions of head of cattle, making it one of the top beef-producing states in the country.
Pork production is another important aspect of Oklahoma agriculture, with the state ranking fifth in the nation for hog production.
The state’s mild climate and ample sunlight make it ideal for growing flowers, plants, and trees.
