USDA hardiness zones present
Agriculture is a foundational part of Oklahoma's economy and rural identity, with farms and ranches covering a large majority of the state's land. Livestock, especially beef cattle, anchors farm income, while winter wheat has long defined the state's row-crop landscape. For growers and gardeners, Oklahoma offers a wide range of conditions, from the humid, wooded east to the dry plains of the west and panhandle.
Farming in Oklahoma
Beef cattle production is the leading agricultural enterprise in Oklahoma, and cattle ranching is found in nearly every county. Winter wheat is the signature crop, often grown for a dual purpose so that fields can be grazed by cattle in fall and winter and then harvested for grain. Other important crops include hay, grain sorghum, cotton in the southwest, soybeans, corn, canola, and peanuts, along with pecans that grow both in native groves and managed orchards. Poultry and hog operations are also significant, with broiler production concentrated in the eastern part of the state.
Climate and growing conditions
Oklahoma's climate shifts from humid subtropical in the east to semi-arid in the western plains and panhandle, so rainfall generally decreases from east to west. The frost-free growing season ranges from roughly 170 days in the panhandle to around 230 days in the far southeast, and summers can be hot with periodic drought and strong winds. USDA hardiness zones across the state run from about 6a in the northwest and panhandle to 8a in the south-central and southeastern areas.
