Yield and quality of five major Macadamia cultivars in Hawaii
, and
Yield and quality of five Macadamia cultivars were analysed for 13 consecutive years of production. Annual yield of in-shell nuts from cultivar ‘Kau’ averaged 47.4kg per tree for the last 7 years on record, followed by ‘Keauhou’, ‘Kakea’, ‘Ikaika’ and ‘Keaau’. ‘Keauhou’ yielded an average of 15.8kg of kernels per year followed closely by ‘Kakea’ m 15.3kg and ‘Kau’, 15.2kg. In an annual yield of No. 1 kernels, ‘Kakea’ produced an average of 13.2kg, ‘Kau’, 12.4 kg and ‘Keaau’, 11.9kg, followed by ‘Ikaika’ with 10.4 kg and ‘ Keauhou’ with 10.2 kg. Production of No. 1 kernels by all five cultivars for the entire 13-year period was similar to the average for the last 7 years.
