Bean

A bean is the seed of plants in many genera of the legume family (Fabaceae) used as a vegetable for human consumption or animal feed. The seeds are sold fresh or preserved through drying. Beans have been cultivated since the seventh millennium BCE in Thailand, and since the second millennium BCE in Europe and in Peru. Most beans, with the exception of peas, are summer crops. As legumes, the plants fix nitrogen and form seeds with a high protein content. They are produced on a scale of millions of tons annually in many countries; India is the largest producer.
