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 acres (39,000,000 ha) of land reserved for corn production. Corn growth is dominated by west/north central Iowa and east central Illinois. Approximately 13% of ...
The quantities of corn (maize, Zea mays) in the following table are in million metric tonnes (m STs, m LTs). All countries with a typical production quantity of at least 10 million t (11 million short tons; 9.8 million long tons) are listed below.
The units by which the yield of a crop is usually measured today are kilograms per hectare or bushels per acre. Long-term cereal yields in the United Kingdom were some 500 kg/ha in Medieval times, jumping to 2000 kg/ha in the Industrial Revolution, and jumping again to 8000 kg/ha in the Green Revolution. [1]
As of 2008, the top four corn-producing states were Iowa, Illinois, Nebraska, and Minnesota, accounting for more than half of the corn growth in the U.S. [7] More recently, the Corn Belt was mapped at the county level using the Land use and Agricultural Management Practices web-Service (LAMPS), [ 8 ] along with animated maps of changes in time ...
Wheat yields in least developed countries since 1961. The steep rise in crop yields in the U.S. began in the 1940s. The percentage of growth was fastest in the early rapid growth stage. In developing countries maize yields are still rapidly rising. [6] Productivity is driven by changes in either agricultural technique or improvements in technology.
The controversies surrounding monocropping are complex, but traditionally the core issues concern the balance between its advantages in increasing short-term food production—especially in hunger-prone regions—and its disadvantages with respect to long-term land stewardship and the fostering of local economic independence and ecological ...

The Illinois long-term selection experiment is an ongoing long-term artificial selection experiment that has been conducted on the kernel of maize (Zea mays) in Illinois since 1896, making it the longest-running directional selection project conducted on plants and one of the longest-running experiments in all of biology.
