In terms of revenue generated Oklahoma's top five agricultural products are cattle and calves, hogs, broilers (young chickens), wheat, and dairy products.
Oklahoma is one of the leading (#5) sources of beef in the country and, not surprisingly, the production of beef cattle is the leading source of agricultural income in the state.
Other important livestock products are hogs (#8), broilers (young chickens), dairy products (milk), chicken eggs, sheep and lambs, turkeys and fish (farm-raised catfish).
Oklahoma's most valuable crop is wheat and the state ranks among the leading (#4) producers in the country.
Greenhouse and nursery products rank second with hay, cotton, soybeans, corn for grain, pecans, grain sorghum, peanuts, watermelons, and rye following.
Peaches and oats are also grown in Oklahoma.

Manufacturers add value to raw products by creating manufactured items. For example, cotton cloth becomes more valuable than a boll of cotton through manufacturing processes.
Production of machinery, particularly oil field machinery, leads the manufacturing industry in Oklahoma. Construction machinery, machine parts and refrigeration and heating equipment are other types of machinery manufactured in the state.
Transportation equipment (aircraft and aerospace equipment, automobile assembly) ranks as the second most important manufacturing activity in the state followed by a variety of other items including computer and electronic equipment (electronic components, military communication systems, telephone equipment), fabricated metal products (structural metal), processed foods (meat-packing plants, animal feed, bakery products), and rubber and plastic products (tires).
Oklahoma's most important mined products are, by a good margin, petroleum and natural gas. The state ranks among the leading producers in the country.
Other mined products are coal, crushed stone (limestone quarries), iodine and sand and gravel. Iodine is not produced in any other state.
In the services industry, the community, business and personal services group leads the way with private health care, equipment rental companies (oil field equipment, rental cars), telemarketing firms (telephone reservation systems) and repair shops.
Ranking next are the wholesale trade (food products, grain, oil and gas, transportation equipment) and retail trade (automobile dealerships, discount stores, food stores, service stations) industries along with government services (public schools, hospitals, military bases).
The third most important service industry in Oklahoma is the finance, insurance and real estate group, fueled by costs associated with the transfer of property and increasing demand for office space.
