Rehabilitating smallholder coffee gardens in Papua New Guinea: 2. The effects of yields during the second year following rehabilitation

Rehabilitation of smallholder coffee gardens has been carried out since 1987 in an attempt to control coffee leaf rust (Hemileia vastatrix). The rehabilitation package included pruning, fencing, drainage, shade control, weed control, fertilizer application and leaf rust control. A study was carried out on 20 smallholder coffee gardens during the second year following rehabilitation (1987/88). Unrehabilitated plots were used as a control.
