In agriculture, a cash crop is a crop which is grown for profit. exampleThe main crops of the state (Espirito Santo) are rice, coffee (one of the most important cash crops in Brazil), cacao, sugarcane, beans, fruit (mostly bananas and papayas),
Crops which are grown specifically to be sold i.e. not to be eaten by the local people. An example of this could be cassava, grown in Brazil and then shipped to Europe for cows to eat.
