This option prepares students to produce, manage, and market plants grown as crops or in landscapes. The aim is to enable graduates to perform competitively in their chosen profession and to have a sufficiently broad educational background to take advantage of the opportunities afforded by changing situations.
This option involves the study of Hawaii’s unique soils and important insects and diseases that affect plants in the tropical environment. This option also familiarizes you with business skills such as management, personnel administration, marketing and accounting.
Our graduates with this degree option have enjoyed stimulating and rewarding careers with public or private botanical gardens, in golf course management, in landscape installation and management, or in commercial production of food and ornamental crops. Some graduates have become field and laboratory research technicians, and agricultural educators in secondary schools.
Many have become field technicians with the U.S. Department of Agriculture or the Hawaii Department of Agriculture, and many of the ag inspectors you see at the Honolulu International Airport are Tropical Plant & Soil Sciences graduates with this degree option.
Students selecting this option need to take Botany 101 and 101L (or their equivalent) or Biology 172 and 172L (or their equivalent) and Chemistry 15l and 151L and 152 and 152L (or their equivalent) to fulfill the Natural Science requirement of the UH core. These courses are considered prerequisite to courses in the major.

Any HNFAS, NREM, PEPS, GEOG, BOT, ACC, BUS, CHEM, or PHYS course or other TPSS course with approval of the undergraduate academic advisor.
While students may choose from the array of courses offered on the UH campus, an advising list of courses will be available to assist students in selecting courses that prepare students for a career in horticultural crop production and management.
The advising list includes courses in botany, chemistry, biology, physics, geography, business, and courses in other departments; PEPS, MBBE, and NREM. Undergraduate advisers will assist students considering enrollment in graduate school in the selection of appropriate courses.
Students who complete these four courses will earn a Certificate in Agribusiness Management.
Academic Minor in Plant Production and Management
A minimum of 15 credits of non-introductory, upper division level courses must be completed with a grade of C (not C-) or higher for each course. Transfer credits coward the minor will be accepted if an appropriate UH Mānoa course is determined to be equivalent. and if the grade is C (not C-) or higher. Required courses are TPSS 200, 300, and 364. Several optional courses can be selected. Contact the TPSS academic advisor, Dr. Ken Leonhardt, for details.
