Yield Components of Kenaf, 1991 Pulping Conference Proceedings

As the United States approaches commercial production of kenaf (Hibiscus cannabinus L.) as an alternative fiber source for paper pulp and other new uses it becomes important to determine the effect of different cultivars on yield components. The objective of this research was to determine differences between kenaf cultivars and their influence on yield components. Five kenaf cultivars (Tainung #2, Everglades 71, Everglades 41, Cuba 108 and Guatemala 51) were planted on May 8, 1989. Everglades 41 had greater percent stalks (83%) than all other cultivars except Everglades 71. Cuba 108 had less core material (61%), and a greater bark to core ratio (O-63), compared to all cultivars except Everglades 71. Tainung #2 had greater plant heights (316 cm) and stalk diameters at 5 cm (23.6 mm) than all other cultivars. Tainung #2 also had greater stalk yields (17.8 t ha*-l*) than Cuba 108 (13.0 t ha*-l*). As a result of differences between cultivars for the various yield components, the intended use of the crop should be considered when selecting a kenaf cultivar.
