Technical Services

We provide a broad range of analytical and testing services to the food and agricultural industries and our stakeholders

AAESArkansas Agricultural Experiment Station

Arkansas Agricultural Experiment Station

The Arkansas Agricultural Experiment Station is the state’s premier research agency for agriculture, food and natural resources. We are the research arm of the University of Arkansas System Division of Agriculture, one of the 20 institutions in the University of Arkansas System.

About AAES

Our mission is to conduct research and achieve scientific discoveries that benefit Arkansas citizens, expand agricultural sustainability and profitability, promote environmental stewardship, strengthen local and state economies and ensure safe and nutritious food supply.

Research Departments

The 115 AAES appointed faculty on the Fayetteville campus are organized under 9 Departments: Agricultural Economics & Agribusiness; Agricultural Education, Communications and Technology; Animal Science; Biological and Agricultural Engineering; Crop, Soil & Environmental Sciences; Entomology & Plant Pathology; Food Science; Horticulture; and Poultry Science.

Research Locations

Many Arkansans know the AAES through one of our four Research and Extension Centers and six Research Stations that are crucial to our efforts to help Arkansas farmers and other stakeholders adapt to rapid changes in technology, products, methods, and regulations.


Research Highlights

Nutritional interactions with live coccidiosis vaccines in poultry

Coccidiosis is the most prevalent disease in commercial poultry production. As an enteric disease, it directly impacts how efficiently the bird can use nutrients. The most effective anticoccidial drugs also have some antibiotic activity, so as producers move…

ARoma17 gives growers, foodies a domestic alternative for high-yielding fragrant rice

As U.S. consumers continue to explore world cuisines, many have developed a taste for the fragrant jasmine-type rice used in many southern Asian dishes. However, Arkansas, the leading rice growing…

Soybean response to dicamba in irrigation water under controlled environmental conditions

While crop damage from drift of auxin herbicides such as dicamba has received a lot of attention, there isn’t much information about what might happen if a susceptible plant absorbs those herbicides ….

Sustainable control for soybean vein necrosis

Vein necrosis is the most widespread soybean virus disease in North America during hot, dry summers. Soybean vein necrosis virus, or SVNV, reduces seed oil content and is seed-borne, affecting international movement of seed…

Germination Conditions of brown rice and its effects on rice flour in gluten-free bread

Gluten-free products are increasingly popular, however, creating gluten-free foods that offer the same taste, texture and appearance as baked goods with gluten is challenging. Gluten-free baked goods tend to be harder, denser and …

Parboiling with reduced water improves nutrient content of rice

Rice is a staple food for billions of people around the world. However, people relying on rice as their main source of energy are most likely to suffer from nutrient deficiencies such as iron and calcium. Additionally, potassium deficiencies are of concern….

Scientists investigate intersection of salt, insect stress in soybeans

Chlorides, or salts, occur in soils and water sources in many areas of the United States, including much of eastern Arkansas. Soybeans grown in high chloride environments are subject to salt stress …

Genetic discovery may improve soybean drought tolerance

Every year, drought impacts agricultural yield in some part of the world. Soybean, one of the most widely-grown crops on earth, is no exception. When drought conditions strike and yield falls, growers suffer economically…

Researchers add gene editing to rice research toolbox

Variety development is a core effort in the Division of Agriculture research. The need for new breeding material with important genetic traits in environmental tolerances, disease resistance and food quality and yield is never-ending. But it can take …

Wheat breeding lines for resistance to disease

In Arkansas, wheat growers need high yields to make growing wheat profitable. Disease pressure can reduce those yields, impacting the grower’s profitability. Working with Sungrains, a breeding cooperative of six public university breeding programs, Dr. Esten Mason…
