Corn production

irrigating corn with center pivot

  • Corn production in terms of bushels/acre has increased dramatically over the years –from 26 bushels/acre produced in Nebraska in the 1900s to 178 bushels per acre (a new record) produced in 2009.
  • In the last decade, corn yields in Nebraska increased 41%.

Corn Facts

  • An ear of corn averages 800 kernels in 16 rows.
  • A pound of corn consists of about 1,300 kernels.
  • Today, each U.S. farmer produces food and fiber for 155 people in the United States and abroad.
  • A corn plant can be anywhere from 5 to 12 feet tall, on average 8 ft tall by midsummer and a healthy corn’s roots can reach 6 ½ feet into the ground!
  • Corn growth and development occurs in the vegetative and reproductive stages.
  • Different corn plants have different numbers of ears, but some might have 2-3 ears!
  • Silks on corn are essential for pollen from the tassels to fertilize the plant. If its too hot, silks can dry out and not fertilize all sites on a corn cob, thus resulting in a gap on the ear of corn where no kernels developed because they weren’t fertilized.
  • Different kinds of corn are grown for different uses;
             Yellow Dent Corn - Feed, ethanol, Food
             White Dent Corn - Food 
             Popcorn - Yellow, White, Microwave
             Sweetcorn - Food
             High Lysine, High Oil - Specific Uses fro feed or industry 
             Flint Corn - Decoration
  • Of the top five crops grown in America today, corn soybeans, wheat, alfalfa and grain sorghum, only corn is native to America.

Soybean Production

  • Nebraska soybean yields in 2009 averaged more than 54 bushels per acre; in the 1920’s average yield was 14 bushels/acre.
  • Irrigated soybean yields are 62 bushels/acre while rainfed soybeans average 36 bushels/acre.

Soybean Factshandful of soybeans

  • Soybeans are the world's foremost provider of protein and oil.
  • Soybeans are a legume plant related to clover, peas and alfalfa.
  • Soybean vegetative stages are numbered according to how many fully-developed trifoliate leaves are present. The reproductive (R) stages begin at flowering and include pod development, seed development, and plant maturation. Soybean growth and development.
  • A 60-pound bushel of soybeans yields about 48 pounds of protein-rich meal and 11 pounds of oil. There are many uses of soybeans, often not thought of.
  • More soybeans are grown in the United States than any other country in the world.
  • Farmers plant soybeans in late spring.
  • During the summer, soybeans flower and produce 60-80 pods, each holding three pea-sized beans.
  • In the early fall, farmers harvest their crop for soybeans.

Wheat Productionwheat stalks

  • Winter wheat is one of the major field crops grown in Nebraska, along with corn and soybean.
  • In 2007, more than 256,000 acres were grown under irrigation in the state.
  • Nebraska is typically one of the top 10 winter wheat producing states in the U.S.
  • Production is mainly in the western part of Nebraska, but recently acreage in the south central and eastern parts of the state has increased.

Wheat Facts

  • Six classes bring order to about 30 thousand varieties of wheat. They are: Hard Red Winter, Hard Red Spring, Soft Red Winter, Durum, Hard White and Soft White.
  • More foods are made with wheat than any other cereal grain.
  • One bushel of wheat contains approximately one million individual kernels.
  • One bushel of wheat weighs approximately 60 pounds.
  • One bushel of wheat yields approximately 42 pounds of white flour.
  • One bushel of wheat yields approximately 60 pounds of whole-wheat flour.
  • A bushel of wheat yields 42 commercial loaves of white bread (one-and-a-half pound loaves).

Sorghum Facts

  • Sorghum is a coarse, upright growing grass that is used for both grain and forage production. Grain sorghum is shorter and has been bred for higher grain yields.
  • A grain sorghum plant looks a lot like a corn plant but is shorter and more colorful. The head grows on the top of the plant and is white, yellow, red or bronze.
  • Grain sorghum is also called "milo" and is a major feed grain for cattle. Sorghum has a very hard kernel, which makes it resistant to disease and damage but harder to digest for animals.
  • Sorghum is ground, cracked, steam flaked, and/or roasted. It can be cooked like rice, made into porridge, baked into flatbreads and popped like popcorn.
