Corn is one of the world's most important agricultural crops. Native to the Americas, it is now cultivated worldwide. As a wind pollinated plant, corn produces the best yield when many plants are grown together in a field. Home gardeners sometimes experience a poor yield when they grow smaller numbers of corn plants far from a pollen source.
