Department of Plant Agriculture, Ontario Agricultural College

The Horticulture major is for students who want to apply the latest advancements in the biological sciences to contemporary problems in the horticultural industry. This major is appropriate for students with a focus on the management of commercial greenhouses, horticultural production, breeding improved crop varieties, in vitro plant propagation or using turfgrass and other plant species to enhance urban environments. Students can incorporate a variety of field trips, experiential learning in the workplace and independent study into their program of studies.

Students interested in adding a business emphasis to their studies are encouraged to consider the Certificate of Business offered by the Gordon S. Lang School of Business and Economics. This may require an additional semester to complete.

Students interested in organic agriculture should consider the Certificate in Organic Agriculture. 

The Co-op program in Horticulture facilitates the transition of students from academic studies to a professional career by enhancing the integration of theory and practice. 

Major Requirements (Honours)

This is a major within the degree: Bachelor of Science in Agriculture.
