Growing Macadamia Nuts in Hawaii

Abstract

An intensive varietal selection program was begun at the Experiment Station in 1936, when only 5 acres of (seedling) macadamias had been planted in Hawaii. By 1959 over 2000 acres had been planted, mostly of selected clonal varieties named by the Station in 1948. In this bulletin the authors, having published an evaluation of the collection in 1952, narrowed the list of seven named cultivars to three recommended ones based on vigor and bearing capacity but primarily on anthracnose resistance. The bulletin reviews grafting techniques, cultural practices for the young and bearing orchard, major pests and diseases, and processing technology.
