General Information

The Tropical Horticulture specialization is designed to provide students with a well rounded background in horticultural science with special emphasis on the production of tropical and subtropical crops. This specialization offers a wide selection of courses, each providing the student with both the theoretical and hands-on approach to learning. Students learn basic horticultural practices such as grafting, pruning, pest management and cultivating crops that are of economic interest in the tropics, as well as advanced techniques such as plant tissue culture and hormonal manipulation of plants.

Why Study Tropical Horticulture?

Graduates in Tropical Horticulture are highly skilled in managing, producing and marketing horticultural crops, such as anthuriums, indoor foliage plants, hydroponic vegetables, and exotic tropical fruits; therefore, many graduates start their own enterprises.

Student Learning Outcomes

  • Thorough familiarity with the principles of horticulture and sustainable production of fruit, vegetable, and ornamental crops in the tropics.
  • Identify and analyze the factors that affect crop production including the emerging body of knowledge in plant growth and development and the contribution of climatic, environmental, and edaphic factors.
  • Advanced skills in the actual growing and marketing of crops that illustrate economic viability and sustainability of agricultural practices.
  • Interact effectively with all stakeholders of agricultural development in the community and participate in outreach programs that demonstrate cultural sensitivity and integration of new agricultural technologies with indigenous knowledge.
