Cereal crops are mostly grasses cultivated for their edible grains or seeds (actually a fruit called a caryopsis). Cereal grains are grown in greater quantities worldwide than any other type of crop and provides more food energy to the human race than any other crop. In some developing nations, cereal grains constitute practically the entire diet of common folk. In developed nations, cereal consumption is more moderate but still substantial . The word cereal derives from Ceres, the name of the Roman goddess of The Harvest and Agriculture. Grains are traditionally called corn in the United Kingdom, though that word became specified for maize in the United States, Canada and Australia.
The following table shows annual production of major cereal grains, in 19611961 is the earliest year for which FAO statistics are available. and 2005, ranked by 2005 production.* All but buckwheat and quinoa are true grasses.
