Research Station Profile

About the LSU AgCenter

The LSU AgCenter is dedicated to providing innovative research, information and education to improve people’s lives. Working in a statewide network of parish extension offices, research stations and academic departments, the LSU AgCenter helps Louisiana citizens make the best use of natural resources, protect the environment, enhance agricultural enterprises and develop human and community resources.

Research Highlights

The Dean Lee Research Station is one of the most diverse research stations in Louisiana with research efforts in beef cattle, corn, cotton, forages, grain sorghum, soybean, sugarcane, sweet potato, wheat.

Beef Cattle and Forages

Nutritional and nutrition x environment effects on intake, performance, and progeny’s growth and development of crossbred and Brangus cows are under evaluation. Forage research is concentrated on determining the productivity and evaluation of winter and summer annual forages under grazing conditions and their inclusion in sustainable year-round forage systems. Evaluation of management practices to increase profitability of the beef herd is warranted.

Agronomy

The goal of the Agronomy Program is to increase yield and profitability of Louisiana corn, cotton, grain sorghum, soybean, sugarcane, and wheat. Agronomic research efforts include fertility, crop row widths, planting methods, and crop growth efficiency. Official variety evaluations for cotton, corn, grain sorghum, soybean, and wheat are conducted to evaluate yield potential and adaptation of new varieties. These efforts are important to assist in validating crop production techniques and to help improve upon the practices currently utilized by producers.

Field Crops Entomology

Research is focused on insect management and crop response to new and currently registered insecticides, development/updating of economic thresholds in field crops, quantification and characterization of insecticide resistance by target insects. Identification and documentation of invasive insect species, development of IPM programs in field crops and investigation of insect resistance management strategies to evade or mitigate insects that could or have developed resistance to insecticides.

Field Crops Plant Pathology

Research is conducted to evaluate and develop effective plant disease management programs in cotton, corn, grain sorghum, small grains, and soybean. The goal is to develop effective strategies for our stakeholders utilizing cultural practices, genetic resistance, and fungicides. Some of these efforts are directed toward assessing the impact of planting date, identifying disease resistant varieties, and evaluating fungicides for disease development. Other research is aimed toward monitoring for pathogen resistance to fungicides. The unbiased results from this research is used by stakeholders to optimize their production systems and maximize profits.

Weed Management

Research efforts focus on development of strategies to manage weedy pest in corn, cotton, grain sorghum, soybean, and wheat that are economically and environmentally feasible.

Size:
3,000 acres, including 560 acres of field crops research and 820 acres in pasture and beef cattle research.The station also 1,360 acres of timber and wetlands.

Research focus:

  • Agronomy and hybrid/variety testing
  • Insect, Plant Disease, and Weed management in field crops
  • Beef cattle and Forage research

Significance Of Research

  • Research evaluating agronomic and pest management practices that can make Louisiana produces competitive in a global market.
  • Beef cattle research provides information to the stakeholders to improve cattle health and increase productivity.
  • Forage research is aimed at suitability for year-round grazing systems with improved efficiencies.
  • Each year, over 50 cotton varieties, 50 corn hybrids, 25 grain sorghum hybrids, and 150 soybean varieties are evaluated in the LSU AgCenter Official Variety/Hybrid Trial. These studies provide important information to farmers for variety/hybrid selection.
  • Disease resistant crop varieties/hybrids have been identified in the Official Variety/Hybrid Trials and Plant Introduction tests. These varieties can be utilized by stakeholders which reduces the need for fungicides for disease management. This also reduces the pesticide load in the environment.
  • Evaluation of weed management programs utilizing chemical, cultural, and mechanical methods to provide Louisiana crops producers with strategies that can increase productivity while being economically and environmentally feasible.

2019 Louisiana Agricultural Statistics

  • Total gross farm value generated by beef cattle was approximately $345 million.
  • Statewide acreage of crops researched at the Dean Lee Research Station are:
      • Corn – 545,000
      • Cotton – 211,000
      • Grain sorghum – 6,000
      • Soybean – 888,000
      • Sugarcane – 480,000
      • Sweet potato – 7,200
      • Wheat – 14,000.
  • Gross farm value of corn, cotton, grain sorghum, soybean, sugarcane, sweet potato, and wheat in Louisiana was $1.53 billion.
  • Data from the Louisiana Ag Summary at www.LSUAgCenter.com/agsummary.

    Future Plans

  • 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 will be researched as needed.
  • Research on newly released varieties/hybrids that contain tolerances to various herbicides, insects, and diseases will be a focus area of the program in the future. As higher-yielding varieties/hybrids are continually introduced, research on their management and adaptation will be needed to optimize production and profitability for Louisiana farmers.
  • With the growth of sugarcane acreage in Central Louisiana, the LSU AgCenter added a research/extension scientist responsible for sugarcane and soybean agronomy.
  • The LSU AgCenter is committed to providing our stakeholders with unbiased information on disease, insect, and weed management. Therefore, research will continue in the future and evolve with the changing agricultural landscape to address stakeholder needs and keep them profitable.
  • Louisiana Agricultural Experiment Station

    Louisiana Agricultural Experiment Station

    Louisiana’s unique combination of crops — ranging from corn, cotton, rice and sugarcane to extensive forestry, poultry, cattle and fisheries industries — presents challenges for providing research-based information to ensure sustainable agricultural production systems.

    To address the needs of these industries, the Louisiana Agricultural Experiment Station operates 14 departments shared by the LSU AgCenter and the LSU College of Agriculture, as well as 15 research locations across the state. To fund the basic and applied research, scientists compete for federal and state grants and checkoff dollars provided by some farmers’ groups, along with state and federal dollars. Many of the facilities also sustain their research operations through the sale of agricultural commodities produced on the stations.

    The LSU AgCenter has the most successful record of commercialization of intellectual property in the LSU System. Since 2000, 18 new companies have been started based on licensed technology from LSU AgCenter. The income is distributed among the LSU System, the inventors and more research.
