Alyssa H Cho

Assistant Researcher 


Sustainable farming systems; tropical fruits and nuts


Ph.D. Agronomy, Tropical Conservation and Development, University of Florida
M.S. Horticultural Sciences, University of Florida
B.S. NREM, University of Hawaii at Manoa

Courses Taught:

Research Interests:

Variety by environment evaluation, sustainable weed management, cropping systems, sustainable land use practices.

The sustainable tropical fruit and nut systems lab aims to develop interdisciplinary teams to address issues related to tropical fruit and nut production. Sustainable production must be economically, environmentally and socially viable.

Research programs in this lab take into consideration the input from industry groups, associations, and partners to develop studies that will address the needs of our stakeholders. Examples of crops that are currently being addressed in this lab include: Macadamia nut, Papaya, Coffee, Cacao, Avocado, Breadfruit, and Mango.

Current research focuses on integrated pest and nutrient management in macadamia nut orchards to maintain the productivity of the orchards and ensure longevity of the industry. For more information, please visit the lab website (link is below).
