Plant, Soil, and Environmental Sciences

Department of Plant Sciences

The Doctor of Philosophy with a major in plant, soil and environmental sciences and concentrations in crop sciences, horticulture, plant breeding, plant molecular genetics, and weed science is offered under a multi-departmental doctoral program. Two departments participate – Plant Sciences and the soils faculty in Biosystems Engineering and Soil Science. Another concentration within the plant, soil and environmental sciences major is environmental and soil sciences.

Students must select a formal concentration as a focus of study. We recognize that modern research approaches in plant sciences often overlap. Students may specialize in one or more approaches, including plant biotechnology, molecular biology, breeding, genetics, physiology, ecology, culture and management. Research approaches may be applied to model plant systems, public horticulture, turfgrass, weeds, or woody ornamental plants, as well as fruit, vegetable, cereal, grain, or fiber crops.
