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


, : Rehabilitating smallholder coffee gardens in Papua New Guinea: 2. The effects of yields during the second year following rehabilitation. PNG Coffee 9(1): 3-14

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.

Normal and fluorotic primary and permanent human teeth were demineralized in 10% EDTA at pH 7 for varying periods of time up to 4 wk. The fluorotic teeth initially dissolved at a much slower rate than non-fluorotic specimens and appeared to contai...

Augmented histamine tests and gastric mucosal biopsies were performed on 97 patients. The amount of acid secreted was closely correlated with the histologic appearances of the gastric mucosa. There was a striking difference between the acid secret...

Differences in pathogenicity were not detected between the colour mutant and the subbi...
