As a result, DeKalb was the leader in U.S. hybrid seed corn sales from the mid-1930s until the mid-1970s (Crabb 1948. Roberts 1999). [2] In 1982 DeKalb formed a joint venture with Pfizer, called DeKalb-Pfizer Genetics, and in 1985 the name was changed to DeKalb Corporation. The seed business was spun off as DeKalb Genetics Corporation in 1988. [4]
The middle plot was originally planted in a rotation of corn and oats, with the oats replaced by soybeans in 1968. The southern plot was originally planted in a rotation of two years of corn, one year of oats, and three years clover; this was replaced in 1901 by a rotation of corn, oats, and clover, and in 1953 by corn, oats, and alfalfa.

In agriculture, the yield is a measurement of the amount of a crop grown, or product such as wool, meat or milk produced, per unit area of land. The seed ratio is another way of calculating yields. Cereal yield in tons per hectare and kilograms of nitrogenous fertilizer applied per hectare of cropland.
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.
The oldest type of sweet corn contains more sugar and less starch than field corn intended for livestock. Tends to be heartier in respect to planting depth, germination and growth than other types. Begins conversion of sugar to starch after peak maturity or harvest, and as such is best eaten immediately after harvest.
DeKalb played a leading role in the development of commercial hybrid corn. [6]: 46–49 From a base in the early county Farm Bureau, the DeKalb Agricultural Association produced large quantities of high-yield seed varieties, beginning in 1934. Until the mid-1970s, more American farmers planted DeKalb hybrid corn than any other brand.
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.
