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.

Grading:

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%
  100%
