Abstract

SUMMARY Kenaf (Hibiscus cannabinus L.), an herbaceous annual, is a potential source of raw material for the pulp industry. It is adapted to warm growing conditions and is capable of high productivity. Pulping tests have shown that the bark and wood fractions of the stem can be pulped by conventional processes to give pulps comparable with commercial wood pulps. The seed and the leaves could also be valuable by-products. A preliminary appraisal of its potential is made on the basis of field trials conducted at Kimberley Research Station in the Ord Irrigation Area. Comparisons are made with forests in relation to productivity, production economics, land resources and environmental impact. It is concluded that there are reasonable prospects of kenaf being grown profitably under irrigation in northern Australia if it could be sold at the present U.S.A. f.o.b. price for woodchips. However, profitable production would require utilisation of the leaves and seed.
