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]
Wheat is produced in almost every state in the United States, and is one of the most grown grains in the country. [1] The type and quantity vary between regions. The US is ranked fourth in production volume of wheat, with almost 50 million tons produced in 2020, behind only China, India and Russia. [2]
The following international wheat production statistics come from the Food and Agriculture Organization figures from FAOSTAT database, older from International Grains Council figures from the report "Grain Market Report". The quantities of wheat in the following table are in million metric tonnes. All countries with a typical production ...
Between 1930 and 1942, the United States' share of world soybean production grew from 3% to 47%, and by 1969 it had risen to 76%. By 1973 soybeans were the United States' "number one cash crop, and leading export commodity, ahead of both wheat and corn". [8] Although soybeans developed as the top cash crop, corn also remains as an important ...
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 value and production of individual crops varies substantially from year to year as prices fluctuate on the world and country markets and weather and other factors influence production. This list includes the top 50 most valuable crops and livestock products but does not necessarily include the top 50 most heavily produced crops and ...
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 ...
The world record wheat yield is about 17 tonnes per hectare (15,000 pounds per acre), reached in New Zealand in 2017. [159] A project in the UK, led by Rothamsted Research has aimed to raise wheat yields in the country to 20 t/ha (18,000 lb/acre) by 2020, but in 2018 the UK record stood at 16 t/ha (14,000 lb/acre), and the average yield was ...
