Research for Agriculture, the Environment,
Consumers, Families and Communities

The Arkansas Agricultural Experiment Station is the research component of the Division of Agriculture. AAES is the primary research support agency for Arkansas farmers and ranchers, food processors, related industries and consumers. Research topics also include issues that impact the families, communities and natural resources associated with Arkansas agriculture.

We conduct basic and applied research at five research and extension centers and six research stations around the state, as well as at the University of Arkansas, Fayetteville; the University of Arkansas at Monticello; the University of Arkansas at Pine Bluff; and Arkansas State University, Jonesboro. AAES research discoveries allow Arkansas farmers, businesses, communities and families to adopt new technologies and products, and adapt to changes in regulations. Our research personnel maintain partnerships with state, federal and international agencies and professional societies that connect us to worldwide communities of scientists.

  Dicamba resistance in pigweed selected in research greenhouse, not in the field

University of Arkansas System Division of Agriculture researchers have selected for dicamba-resistant pigweed, documenting how genetic resistance develops and how the industry must work to protect the few remaining weed-fighting options. Bob Scott, an extension weed scientist, emphasized that the finding was the result of controlled greenhouse studies and not a confirmation of anything found in any field. 

  Senator Bumpers remembered as agricultural icon

As hundreds gathered Sunday, Jan. 10, to celebrate the life of Sen. Dale Bumpers, agricultural leaders in Arkansas are remembering his monumental contributions to the state’s top industry and his passion for serving the state’s agriculture community.
