The emphasis will be placed, as much as possible, on crops and methods appropriate for small-scale production in Hawaii, with the intent of exposing you to the potential for a financially and personally rewarding career in tropical fruit crop production in our state.

Field Trips:

Visit to the Big Island for 3 days during Spring Break to look at successful horticultural enterprises and meet the entrepreneurs, as well as USDA and CTAHR researchers and their projects.

Course organization:

Lectures on specific crops (macadamia nut, coffee, guava, passionfruit, bananas, papaya, pineapple, mango, etc.) follow the following format:

  • Introduction - Common names, uses of fruit, nutritional value, importance in World and Hawaiian markets.
  • Taxonomy - Botanical family and characteristics, scientific names of species, origin and evolution of crop.
  • Botany - Descriptions of growth habit, leaf shape and arrangement, flower type and reproductive biology, fruit type, and biochemical aspects.
  • Culture and Management - Environmental requirements, propagation, spacing, training and pruning, irrigation, fertilization, weed, disease and pest control, harvesting and handling.
  • Varieties and Breeding - Important local Hawaiian cultivars and current efforts to improve existing varieties.


Three (3) tests will be given during the semester, including the final exam. The tests will consist of questions requiring a short written paragraph or diagram. The tests will be mostly non-cumulative, so that for the most part you will be tested only on information presented since the previous exam.

Each student will research, document photographically, and produce a 25-minute video presentation of some topic relating to tropical fruit crop production. The TA and I will help you choose appropriate topics and learn the computer and camera skills required to make the presentation.

Your class grade will consist of the following:

Exam 1 20%
Exam 2 20%
Exam 20%
Labs (8 x 2.5%) 20%
Presentation 20%
