An ample irrigation supply, favorable climate and rich soils have allowed Nebraska to be the top producer of popcorn in the country for several years. Approximately 34 percent of the U.S. popcorn supply is produced in the state. The production process for popcorn is very similar to that of field corn and to most people, a corn plant and popcorn plant will look very similar. Yields from one acre of popcorn range from 50 to 100 bushels, depending on production techniques and the use of irrigation.
