In agriculture, a cash crop is a crop which is grown for profit. The term is used to differentiate from subsistence crops, which are those fed to the producer's own livestock or grown as food for the producer's family. In earlier times cash crops were usually only a small (but vital) part of a farm's total yield, while today, especially in the developed countries, almost all crops are mainly grown for cash. In non-developed nations, cash crops are usually crops which attract demand in more developed nations, and hence have some export value. In many tropical and subtropical areas, jute, coffee, cocoa, sugar cane, bananas, oranges and cotton are common cash crops. In cooler areas, grain crops, oil-yielding crops and some vegetables predominate; an example of this is the United States, where corn, wheat, soybean are the predominant cash crops. Tobacco has historically been a cash crop, though with increased pressures from anti-tobacco activists, it has declined in popularity; the largest profiters from tobacco today tend to be governments, which in many places add taxes that more than double the cost of tobacco products.
