You can access a PDF version of the Dean Lee Research Station Profile below.
From cotton and corn to soybeans and cattle, just about every major agricultural commodity in Louisiana grows in central Louisiana. The LSU AgCenter’s Dean Lee Research and Extension Station in Alexandria serves this region, the heart of Louisiana agriculture. The station is six miles south of Alexandria on Highway 71 adjacent the LSU-Alexandria campus.
8105 Tom Bowman Drive, Alexandria, LA 71302
Office Hours: 7:30 a.m. – 4 :30 p.m., Monday-Friday
The station includes 3,155 acres – 900 acres of pasture, 650 acres row crops and 1,200 acres of hardwood timber.

Agronomy Research and Variety Testing
The goal of the Agronomy Project is to increase yield and profit potential for Louisiana cotton, corn, soybean, and grain sorghum producers. Research evaluating row widths and planting methods are important to validate and improve upon the practices currently used by producers. Official variety trials for cotton, corn, and soybean are conducted to evaluate the yield potential and adaptation of new varieties before producers risk planting them on large acreages.
Breeding Corn for Resistance to Aflatoxin
Efforts are underway to introduce aflatoxin-resistance genes from tropical corn lines into inbred lines that are adapted to Louisiana growing conditions. Genetic resistance to aflatoxin accumulation would be extremely valuable to Louisiana producers because there are no chemical control methods to reduce aflatoxin to acceptable levels in contaminated grain.
Performance Bull Testing
The purpose of the performance bull testing program is to compare the gain potential of bulls under uniform environmental conditions. The program conducted at the Dean Lee Research & Extension Center began in 1958 and is one of the oldest programs in the United States.
Weed Science Research
Research responsibilities include the evaluation of weed control and crop response to new and currently registered herbicides, development of weed management systems, herbicide resistance, and programs utilizing genetically modified crops for corn, cotton, grain sorghum, soybean, and wheat in the Lower Red River Valley of Louisiana. Identification and documentation of herbicide resistant weeds and the development designed to evade or mitigate weeds that could or have developed resistance to herbicides.
Studies are being conducted investigating specific genetic factors affecting disease resistance and susceptibility in growing beef cattle. Other studies are also being conducted exploring genetic influences for improved heat tolerance in Louisiana’s sub-topical environment.

Research efforts will continue to address the changing landscape of crop production methods and techniques. The commodity markets will continue to influence Louisiana crop production and new crops and rotations, including bio fuel crops, will be researched as needed. Up-to-date research on newly released varieties will be a focus area of the program in the future. As higher-yielding varieties are continually introduced, research on their management and adaptation will be needed to optimize production and profitability for Louisiana farmers. In cotton, corn, and soybean, complex combinations of genetic technologies are now included in the seed. Management of these genetic technologies, and information such as when and where they are needed, will be an important part of variety testing in the future.
Research efforts will continue to address crop and weed response to herbicides and to develop economical and environmentally feasible weed management strategies for the betterment of crop producers in the Louisiana Lower Red River Valley.
Research will continue on studying various genetic considerations as well as management.
