Agricultural Business: Plant Science Concentration

Program Highlights

Louisiana Tech University is the only institution in the central to north Louisiana region that offers a degree program in Agricultural Business with a concentration in Plant Science. Students enrolled in this concentration can choose from a broad range of Plant Science courses that encompass areas such as horticultural production, landscape design and contracting, agronomic applications, integrated pest management strategies, and soil and water management.  The facilities offer students hands-on experience in a variety of settings that include the Louisiana Tech Greenhouses, the John D. Griffin Horticultural Gardens, Louisiana Tech Farm, outside nursery areas, and raised bed vegetable gardens.  Students can also get involved in the Plant Science club “Greenscape”.

Graduates of the Program

Graduates with a degree in Agricultural Business with a concentration in Plant Science have many options for a career path.  The following list contains examples of positions that may be options for graduates of the program: landscape contractor, landscape designer, greenhouse/nursery manager, golf course grounds manager, agricultural crop consultant, pesticide sales, agricultural equipment sales, County/Parish extension agent, USDA program specialist, high school agriculture teacher, laboratory supervisor, and agricultural producer.

The degree program also lays an excellent foundation for students who choose to further their education in graduate school.  Pursuing a Master’s degree in areas such as Horticulture, Agronomy, Plant Pathology, Entomology, Weed Science, Agricultural Economics, and Business Administration (available at Louisiana Tech) are just a few of the options students may choose to pursue after earning their Bachelor’s degree in Agricultural Business with a concentration in Plant Science.

Curriculum Information

A Plant Science minor is built in to the concentration.  To earn the minor, a student must complete 18 hours of Plant Science courses with nine of those credit hours being required at a 300 or 400 level. Students enrolled in the Agricultural Business concentration and in other degree programs such as Animal Science, Agricultural Education, and Environmental Science (School of Biological Sciences) will often minor in Plant Science.  Earning the Plant Science minor in these other degree programs is accomplished by using electives built in to their respective curricula.

Some Plant Science courses are offered annually while others vary depending on student interest and faculty availability. The following is a list of Plant Science course offerings from the Louisiana Tech University catalog. The (G) stands for graduate credit.  Students enrolled in the Master of Science program in the School of Biological Sciences have the option of including graduate level courses on their plan of study.
