The ears are stripped from the stalk, and the kernels are shelled from the cob in the combine.
Typically, a combine is used to harvest the popcorn. The popcorn is ready to harvest when the kernels become hard and the stalk and leaves of the plant are brown and dry. After successful fertilization, a kernel develops and the silk detaches. The pollen travels down a small tube in each silk and fertilizes the ovule at the base. The ears form silks that catch the pollen as the wind blows. The pollen is located in the tassels at the top of the plant. The plant can grow to about 8 feet high and produce ears of corn covered in a green husk. Popcorn is a type of maize (corn) scientifically known as Sea mays everta. There are five different types of corn-sweet corn, popcorn, dent (field) corn, flour corn, and flint corn-but only one kind that pops.popcorn!

The majority of the popcorn consumed worldwide is grown in the Corn Belt of the United States covering Iowa, Illinois, Indiana, southern Michigan, western Ohio, eastern Nebraska, eastern Kansas, southern Minnesota, and Missouri. 3 13 billion quarts averages out to about 42 quarts (40 L) or 10.5 gallons per person. Cortez noted this in 1519 when he came into contact with the Aztecs, who used it to create exquisite decorations like ceremonial headdresses, necklaces, and ornaments on statues.Īmericans today consume 13 billion quarts of popcorn each year, more than any country in the world. 2 Native tribes from North and South America relied on popcorn as an important food staple but also used it as a decoration.
