Wheat

Wheat is grown on more than 240 million hectares, larger than for any other crop. World trade in wheat is greater than for all other crops combined. With rice, wheat is the world's most favored staple food. Wheat provides more nourishment for humans than any other food source. It is a major diet component because of the wheat plant's agronomic adaptability with the ability to grow from near arctic regions to equator, from sea level to plains of Tibet (4000 meters above sea level)
