University of Hawaii at Manoa

What you'll study

This programme covers the fundamental biological sciences that underpin plant growth together with applied subjects specific to tropical and island environments. Core topics typically include plant physiology, plant anatomy and development, plant taxonomy and ecology, soil science, crop science, and pest and disease management. Practical laboratory and field skills are emphasised through courses in plant propagation, greenhouse management, molecular methods in plant biology, and hands‑on crop production.

Students follow a mix of required core courses and electives that allow specialisation in areas such as tropical horticulture, sustainable agriculture, plant breeding and genetics, weed science, or integrated pest management. The degree usually includes a capstone experience — such as an independent research project, a practicum at one of the university’s research stations, or an internship with local growers, extension services or conservation organisations — to apply classroom learning to real‑world plant systems.

• Plant physiology and development

Entry requirements

Applicants are expected to meet the University of Hawaiʻi at Mānoa’s undergraduate admission criteria and provide evidence of readiness for science study. Typical expectations include a high‑school diploma (or recognised equivalent) with strong performance in biology, chemistry and mathematics. Prior laboratory or field experience is an advantage but not always mandatory.

International applicants may present qualifications such as the International Baccalaureate or other recognised credentials; transfer applicants from community colleges or other universities will usually be assessed on completed college coursework and GPA. Some programmes may require placement testing in mathematics or English before enrolling in certain courses. Prospective students should consult the university’s admissions office for specific required documentation and any programme‑specific prerequisites.

Career prospects

Graduates with a Bachelor’s in Plant Sciences from the University of Hawaiʻi at Mānoa enter a range of careers across agriculture, horticulture, conservation and research. Common roles include agronomist, crop or nursery manager, horticulturist, extension agent, pest management specialist, seed technologist and greenhouse or landscape manager. The degree also provides a strong foundation for employment with government agencies, non‑profit conservation organisations, botanical gardens and private industry involved in plant production, postharvest handling or plant biotechnology.

Many graduates pursue further study at the master’s or doctoral level in plant science, agronomy, plant pathology or related fields, or take professional training in fields such as environmental management, agricultural consultancy and extension education.

Why study at University of Hawaii at Manoa

The University of Hawaiʻi at Mānoa offers distinctive strengths for plant science students because of its Pacific island location and the university’s College of Tropical Agriculture and Human Resources. Students benefit from direct access to tropical research farms, living laboratory sites across the Hawaiian Islands and extension networks that connect academic study with local growers and communities.

Study at Mānoa provides opportunities to work on plant systems and crops that are ecologically and economically important in tropical and subtropical regions, and to engage in interdisciplinary projects addressing sustainability, invasive species, biosecurity and food systems in the Pacific. Small class sizes in many practical courses, experienced faculty with regional expertise, and partnerships with local industry and government research stations support hands‑on learning and career development.
