Crop | Wikipedia audio article

A crop is a plant or animal product that can
be grown and harvested extensively for profit or subsistence. Crop may refer either to the harvested parts
or to the harvest in a more refined state. Most crops are cultivated in agriculture or
aquaculture. A crop is usually expanded to include macroscopic
fungus (e.g. mushrooms), or alga (algaculture). Most crops are harvested as food for humans
or fodder for livestock. Some crops are gathered from the wild (including
intensive gathering, e.g. ginseng). Important non-food crops include horticulture,
floriculture and industrial crops. Horticulture crops include plants used for
other crops (e.g. fruit trees). Floriculture crops include bedding plants,
houseplants, flowering garden and pot plants, cut cultivated greens, and cut flowers. Industrial crops are produced for clothing
(fiber crops), biofuel (energy crops, algae fuel), or medicine (medicinal plants).==Important food crops==The importance of a crop varies greatly by
region. Globally, the following crops contribute most
to human food supply (values of kcal/person/day for 2013 given in parentheses): rice (541
kcal), wheat (527 kcal), sugarcane and other sugar crops (200 kcal), maize (corn) (147
kcal), soybean oil (82 kcal), other vegetables (74 kcal), potatoes (64 kcal), palm oil (52
kcal), cassava (37 kcal), legume pulses (37 kcal), sunflowerseed oil (35 kcal), rape and
mustard oil (34 kcal), other fruits, (31 kcal), sorghum (28 kcal), millet (27 kcal), groundnuts
(25 kcal), beans (23 kcal), sweet potatoes (22 kcal), bananas (21 kcal), various nuts
(16 kcal), soybeans (14 kcal), cottonseed oil (13 kcal), groundnut oil (13 kcal), yams
(13 kcal). Note that many of the globally apparently
minor crops are regionally very important. For example in Africa, roots & tubers dominate
with 421 kcal/person/day, and sorghum and millet contribute 135 kcal and 90 kcal, respectively.In
terms of produced weight, the following crops are the most important ones (global production
in thousand metric tonnes):==See also
