Sorghum (Sorghum bicolor), also known as milo, has a variety of uses including food for human consumption, feed grain for livestock and industrial applications such as ethanol production. The area planted to sorghum worldwide has increased by 66 percent over the past 50 years, while yield has increased by 244 percent. Around half of the sorghum produced is fed to livestock, and half is consumed by humans and used in other applications.

Currently, most human consumption of sorghum occurs in low-income countries, while high-income countries typically use sorghum as a component in livestock feed or to produce ethanol. Sorghum is a versatile plant because it can tolerate drought, soil toxicities, a wide range of temperatures and high altitudes.


U.S. grain sorghum production in 2012 totaled 246.9 million bushels, up from 2011 but still far below 2010's production of 345.6 million bushels. The increase in production was due primarily to drought recovery in some states, such as Texas and Oklahoma, and increased production in states less affected by drought conditions, such as Arkansas and Louisiana. In Kansas, typically the leading producer of sorghum, production continued to decline, falling to 81.9 million bushels. (NASS 2013)

The value of the U.S. grain sorghum crop was $1.63 billion, up from last year's value of $1.27 billion and slightly larger than 2010's crop value of $1.62 billion. (NASS 2013)

Sorghum is grown in 14 states. Historically, Kansas and Texas have been the top two sorghum-producing states. In 2012 the two states retained their ranking as leading producers but switched places, harvesting 79 percent of the U.S. sorghum crop. Texas produced 112.1 million bushels valued at $703.1 million and Kansas produced 81.9 million bushels valued at $582.5 million. Other states producing large quantities of grain sorghum in 2012 included Louisiana, Arkansas, South Dakota and Oklahoma. (NASS 2013)

Leading producers around the world during 2012 included Mexico, the United States, Nigeria, India and Argentina (FAS 2013).


Since sorghum is primarily used as a livestock feed in the United States, and it does not perform as well as corn (that is, it has a higher feed-to-weight-gain ratio and results in lower average daily gain for livestock) in this capacity, its price is lower. During 2012, the average price for sorghum in the United States continued to increase, rising $2.10 per cwt to $12.80 per cwt (NASS 2013).


Sorghum is increasingly being used in ethanol production. The crop is a good fit for different types of ethanol production including the traditional starch from grain, sugar from pressed juice and high biomass production. In fact, the entire sorghum plant can be used as biomass. Currently, around 12 percent of the U.S. sorghum crop is consumed by ethanol production.

Sweet sorghum is being pursued as a feedstock for half of the ethanol plants planned by Florida companies, including Southeast Renewable Fuels LLC in Fort Lauderdale. Southeast Renewable Fuels has three sweet-sorghum-fueled plants in the works. New Planet Energy LLC, which has an office in Vero Beach, plans to use sorghum as part of the feedstock mix for a plant planned there. Louisiana Green Fuels, LLC, a project in Lacassine, Louisiana, will use an existing sugar cane facility to produce sweet sorghum ethanol. BioDimensions, a west Tennessee company, has assembled a group of farmers, equipment manufacturers and a local bottling company to produce ethanol from sorghum juice.

As of 2012, Kansas had 11 dry mill plants that together produced more than 440 million gallons per year (MGPY) of ethanol, creating a market for 157 million bushels of sorghum and corn. Four ethanol plants in Kansas process both corn and milo, with a total capacity of 143 MGY. The 30 MGPY Abengoa Bionergy plant in Portales, New Mexico, has traditionally used all sorghum when the grain is available.

Exports and Imports

The United States is the leading exporter of sorghum. In recent years, the country has accounted for more than 65 percent of world trade. In 2012 the United States exported grain sorghum valued at $488.8 million, a 49 percent drop from 2011. The largest buyers for U.S. grain sorghum were Mexico, Japan and Sudan. (FAS 2013)

During 2012, U.S. imports of grain sorghum again experienced significant gains. The nation purchased sorghum valued at $6.0 million. Argentina provided the vast majority of the sorghum purchased in 2012. (FAS 2013)

Value-added Products

Globally, about 50 percent of sorghum is consumed by humans, but in the United States over 90 percent of the sorghum consumed is used as a component in livestock feed. Corn is the main substitute for sorghum in livestock feed. The starch and protein in sorghum are more difficult for animals to digest than those in corn, giving corn a distinct advantage for feed usage. However, research is being conducted to develop processing methods that allow animals to digest sorghum more readily. Processing breaks the seed coat, reduces particle size and increases surface area. Some methods of processing make the end-use value of sorghum comparable to that of corn because more starch and protein are able to be digested in sorghum.

While many new sorghum food products are currently being developed, the grain’s food use has been limited thus far. These limitations are mainly due to two characteristics of the plant. First, phenolic acid and tannins cause flour made from sorghum to have a bitter flavor. Second, the lack of gluten restricts sorghum’s usefulness in the food industry. Recently a food-grade sorghum was developed that does not contain phenolic acid or tannins, and thus, the resulting flour does not have a bitter taste. These varieties are being used in snack food applications in the United States and Japan, and can also be used to replace wheat flour in some baked products. The lack of gluten may be an advantage in a niche market, targeting people who are gluten intolerant.

Besides feed and food applications, sorghum is used in several other products. Archer Daniels Midland produces wallboard for the housing industry using sorghum. Due to its lack of conductivity, sorghum is becoming a popular material for biodegradable packaging materials.

Research and Development

While corn and sorghum have similar chemical makeups, corn is easier for livestock to digest and use than is sorghum. However, certain processing techniques can break down the sorghum seed enough so that it is as easy for livestock to use as corn is. Many studies have compared different processing techniques’ effect on various livestock’s ability to digest and use the feed. Studies on cattle show that steam-flaked sorghum was preferable to dry-rolled sorghum because it improved daily gain and feed efficiency. Research also suggested a complementary effect between corn and sorghum in cattle feeding. Sorghum was shown to be a slightly more efficient feed than corn for hogs when similar particle sizes and milling techniques were compared.
