P.J. Ito, R.A. Hamilton, H.H. Hirae

Abstract


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.
