Introduction To Kenaf

Kenaf (Hibiscus cannabinus L.) is a warm season annual closely related to cotton (Gossypium hirsutum L.) and okra (Abelmoschus esculentus L.). Kenaf can be used as a domestic supply of cordage fiber in the manufacture of rope, twine, carpet backing and burlap. Research, in the early 1940s, focused on - the development of high-yielding anthracnose-resistant varieties, cultural practices and harvesting machinery. During the 1950s, kenaf was identified as a promising fiber source for paper pulp. Kenaf fibers have been processed into high quality newsprint and bond paper. Although kenaf is usually considered a fiber crop, research indicates that it has high protein content and, therefore, is a potential livestock feed. Crude protein in kenaf leaves ranged from 21 to 34 percent, stalk crude protein ranged from 10 to 12 percent, and whole-plant crude protein ranged from 16 to 23 percent. Kenaf can be ensilaged effectively, and it has satisfactory digestibility with a high percentage of digestible protein. Digestibility of dry matter and crude proteins in kenaf feeds ranged from 53 to 58 percent, and 59 to 71 percent, respectively Kenaf meal, used as a supplement in a rice ration for sheep, compared favorably with a ration containing alfalfa meal.

In addition to the use of kenaf for cordage, paper pulp and livestock feed researchers have investigated its use as poultry litter and animal bedding, bulking agent for sewage sludge composting and as a potting soil amendment. Additional products include automobile dashboards, carpet padding, corrugated medium, as a "substitute for fiberglass and other synthetic fibers," building materials (particle boards of various densities, thicknesses, and fire and insect resistances), absorbents, textiles and as fibers in extraction molded plastics.
