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 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 ...
Percentage figures for arable land, permanent crops land and other lands are all taken from the CIA World Factbook [1] as well as total land area figures [2] (Note: the total area of a country is defined as the sum of total land area and total water area together.) All other figures, including total cultivated land area, are calculated on the ...
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]
The land equivalent ratio can be used whenever more than one type of yield can be obtained from the same area. This can be intercropping of annual crops (e.g. sorghum and pigeonpea) [1] or combination of annual and perennial crops e.g. in agroforestry systems (e.g. jackfruit and eggplant). [3]
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.
Arable density (m² per capita) by country. This is a list of countries ordered by physiological density."Arable land" is defined by the UN's Food and Agriculture Organization, the source of "Arable land (hectares per person)" as land under temporary crops (double-cropped areas are counted once), temporary meadows for mowing or for pasture, land under market or kitchen gardens, and land ...
By 1906 he owned and 225,000 acres in Illinois, Kansas, Nebraska, and Missouri, renting it out to 1200 tenants. [ 10 ] On account of new agricultural technology developments between 1860 and 1970, the Corn Belt went from producing mixed crops and livestock into becoming an area focused strictly on wheat-cash planting.
