Journal ArticleHarding, P.E. (1990) Rehabilitating smallholder coffee gardens in Papua New Guinea: 3. The effects on yields during the third year following rehabilitation, In: PNG Coffee, Vol.9 (1), 15-22, PNG Coffee Research Institute, Kainantu, Eastern HighlandsnullThe effects on yields during the third year following rehabilitation of shaded smallholder coffee gardens are investigated. Yields from rehabilitated coffee exceeded those from unrehabilitated coffee by 161%, average yields being 1.0 and 0.4 tonnes green bean/ha/year respectively. When yields are adjusted for the effects of one other significant factor and covariate, rehabilitation increased yields by 175%. Rehabilitated coffee may be less prone to biennial bearing than unrehabilitated coffee.nullPNGCoffee_V9N1P15-22.pdfnull401.94 KB, PDF
