Cash crop

A cash crop is a crop that is grown to be sold on the market. This is different from a subsistence crop which is grown for the personal use of the farmer, or as food for the farmer's animals.
There are several different categories of cash crops, for different purposes.
Foods.
Food crops are grown to be eaten by humans or animals. Since modern agriculture(farming) methods allow farmers to grow much more food than they need to feed themselves and their families, the extra is sold to others.
Some food crops include:
Spices and Herbs.
