Just outside of Shreveport, the Pecan Research and Extension Station covers about 90 acres, 65 of which are in pecan trees. The U.S. Department of Agriculture established the facility in 1930 and transferred it to the LSU AgCenter in 1973. It is the only university research facility in the country exclusively devoted to this nut crop. The research focus remains the same – develop management practices to make pecan growing more profitable, not only in Louisiana but all over the Southeast. On average, pecan production adds about $12 million to the Louisiana economy each year.
