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]
Food production per capita since 1961 Grain silos Rice plantation in Thailand Cambodians planting rice, 2004. Agricultural productivity is measured as the ratio of agricultural outputs to inputs. [1] While individual products are usually measured by weight, which is known as crop yield, varying products make measuring overall agricultural ...
Corn is Minnesota's largest crop. In 1922–1931, production averaged 30.4 bushels per acre; in 1947–1956, it average 46.6 bushels per acre; in 1973, it averaged 91.4 bushels per acre; and in 1994, the average was 142 bushels per acre. In 1935–1946, a shift to hybrid varieties occurred. [32] In 2010, the state produced 1.29 billion bushels ...

For example, average yields of corn (maize) in the US have increased from around 2.5 tons per hectare (t/ha) (40 bushels per acre) in 1900 to about 9.4 t/ha (150 bushels per acre) in 2001. Similarly, worldwide average wheat yields have increased from less than 1 t/ha in 1900 to more than 2.5 t/ha in 1990. South American average wheat yields are ...

It is also used to describe average yields. Normal production would be the normal crop acreage planted multiplied by the normal yield. These measures, once required by commodity programs to calculate benefits, are replaced by base acres, payment acres, and payment yield under the 2002 farm bill (P.L. 101-171, Sec. 1101-1102).
