The US is the world's largest producer of corn. [8] According to the United States Department of Agriculture (USDA), the average U.S. yield for corn was 177 bushels per acre, up 3.3 percent over 2020 and a record high, with 16 states posting state records in output, and Iowa reporting a record of 205 bushels of corn per acre.
Corn field in Liechtenstein. Corn stover consists of the leaves, stalks, and cobs of corn (maize) (Zea mays ssp. mays L.) plants left in a field after harvest. Such stover makes up about half of the yield of a corn crop [1] and is similar to straw from other cereal grasses; in Britain it is sometimes called corn straw. Corn stover is a very ...
Stewart's Wilt causes minor reductions in field corn yield, despite common occurrence, because most hybrids grown in the Midwest have adequate resistance. However, the disease can be problematic in seed production because many countries have restrictions on maize seed from areas where the Stewart's Wilt occurs.

Aug. 26—The Hay and Grain Department at this year's Crawford County Fair had some help in recognizing and rewarding the farmers in Crawford County who chose to enter their crops at this year's fair.
Corn grey leaf spot can be an extremely devastating disease as potential yield losses range from 5 to 40 US bushels per acre (440 to 3,480 L/ha). At higher disease levels, even greater losses can result. When a corn plant's ability to store and produce carbohydrates (glucose) in the grain is diminished, yield losses take place.
The tassel of a corn plant. Detasseling corn is removing the pollen-producing flowers, the tassel, from the tops of corn (maize) plants and placing them on the ground. It is a form of pollination control, [1] employed to cross-breed, or hybridize, two varieties of corn. Fields of corn that will be detasseled are planted with two varieties of corn.
Those of economic importance include diseases of the leaf, smuts such as corn smut, ear rots and stalk rots. [85] Northern corn leaf blight damages maize throughout its range, whereas banded leaf and sheath blight is a problem in Asia. [86] [87] Some fungal diseases of maize produce potentially dangerous mycotoxins such as aflatoxin. [60]
