The Department of Plant and Environmental Sciences (PES) is committed to developing and maintaining an inclusive, welcoming and equitable environment for students, faculty and staff that recognizes, encourages and embraces diverse backgrounds, cultures, experiences and aspirations. PES encourages all to join our diverse department in the study of plant and environmental sciences that will contribute to sustaining the people and environment of New Mexico and the world.
The Department of Plant and Environmental Sciences, formerly Agronomy and Horticulture, was formed in 1986 from the merging of the Crop and Soil Science department with the Horticulture department. Our department consists of more than 30 faculty, including numerous off-campus faculty with exclusive research appointments, as well as several affiliate faculty.
