Although soybeans developed as the top cash crop, corn also remains as an important commodity. As the basis for "industrial food," corn is found in most modern day items at the grocery store. Aside from items like candy and soda, which contain high fructose corn-syrup, corn is also found in non-edible items like the shining wax on store advertisements.

Title: Cash crop
Content:   Cash cropping in the United States rose to prominence after the baby boomer generation and the end of World War II. It was seen as a way to feed the large population boom and continues to be the main factor in having an affordable food supply in the United States. According to the 1997 U.S. Census of Agriculture, 90% of the farms in the United States are still owned by families, with an additional 6% owned by a partnership. Cash crop farmers have utilized precision agricultural technologies combined with time-tested practices to produce affordable food. Based upon United States Department of Agriculture (USDA) statistics for 2010, states with the highest fruit production quantities are California, Florida and Washington.

The American South has historically been a large producer of cotton, tobacco, and rice, but it has declined in agricultural production over the past century. The U.S. has led developments in seed improvement, such as hybridization, and in expanding uses for crops from the work of George Washington Carver to bioplastics and biofuels. The mechanization of farming and intensive farming have been major themes in U.S. history, including John Deere's steel plow, Cyrus McCormick's mechanical reaper, Eli Whitney's cotton gin, and the widespread success of the Fordson tractor and the combine harvester. Modern agriculture in the U.S. ranges from hobby farms and small-scale producers to large commercial farms covering thousands of acres of cropland or rangeland.

Title: Rice production in the United States
Content:  Rice production is the third largest among cereals in the United States, after corn and wheat. Of the country's row crop farms, rice farms are the most capital-intensive, and have the highest national land rental rate average. In the US, all rice acreage requires irrigation. In 2000-09 approximately 3.1 million acres in the US were under rice production; an increase was expected over the next decade to approximately 3.3 million acres. USA Rice represents rice producers in the six largest rice-producing states of Arkansas, California, Louisiana, Mississippi, Missouri, and Texas.

Content:  The production of corn (Zea mays mays, also known as "maize") plays a major role in the economy of the United States. The US is the largest corn producer in the world, with 96,000,000 acre of land reserved for corn production. Corn growth is dominated by west/north central Iowa and east central Illinois.

Content:  As one of the most popular crops in the United States, in 2017 over 1.5 e9lb of pumpkins were produced. The top pumpkin-producing states include Illinois, Indiana, Ohio, Pennsylvania, and California. According to the Illinois Department of Agriculture, 95% of the U.S. crop intended for processing is grown in Illinois. The United States Department of Agriculture quotes a much more modest share: 41% of the overall pumpkin crop originates in the state, still more than five times the nearest competitor (California, whose pumpkin industry is centered in the San Joaquin Valley), and the majority of that comes from five counties in the central part of the state.
