Journal ArticleHarding, P.E. (1990) Rehabilitating smallholder coffee gardens in Papua New Guinea: 2. The effects on yields during the second year following rehabilitation, In: PNG Coffee, Vol.9 (1), 3-14nullThe effects on yields during the second year following rehabilitation of shaded smallholder coffee gardens are investigated. Yields from rehabilitated coffee exceeded those from unrehabilitated coffee by 9.3%, average yields being 1.6 and 1.5 tonnes green bean/ha/year respectively. When yields are adjusted for the effects of two other significant covariates, rehabilitation increased yields by almost 50%. New uprights, initiated by the rehabilitation, accounted for only 1.4% of the total harvested crop.
