PhD in Horticultural Sciences- Organic and Sustainable Horticulture in Gainesville United States | University of Florida

Organic farming emphasizes combining environmental, economic, and social approaches that align with USDA National Organic Program standards. Our research team collaborates with growers, buyers, and multidisciplinary experts worldwide to create advanced agricultural methods that maintain ecosystem health, biodiversity, and farm profitability. We focus on establishing premium fruit and vegetable cultivation techniques that protect Florida's natural assets while satisfying market needs locally and internationally.
The Horticultural Sciences (HOS) graduate program is a collaborative effort between the Environmental Horticulture (HSE) and Horticultural Sciences (HS) departments, providing Master of Science (with thesis or non-thesis tracks) and Doctor of Philosophy degree options. The department also features an accelerated bachelor's/master's degree pathway. Prospective students should consult the graduate coordinator for details. The program's Graduate Faculty comprises both campus-based professors and researchers from University of Florida facilities across the state. The Ph.D. represents the highest research achievement, awarded based on comprehensive knowledge, specialized expertise, and demonstrated capacity for independent study through an original dissertation. Accordingly, doctoral curricula offer greater flexibility than master's programs. Ph.D. candidates must complete a minimum of 90 credits post-bachelor's, with course requirements tailored to individual research focuses. Students may transfer up to 30 credits from a master's program, provided they were earned within seven years (extensions possible by petition). The Graduate Council allows departments to determine specific Ph.D. course requirements.
