Yield Components of Five Kenaf Cultivars
1993
Weber, Charles L.
As the USA approaches commercial production of kenaf (Hibiscus cannabinus L.) as an alternative fiber source for paper pulp and other uses, additional information is needed concerning the relationship among kenaf yield components. Kenaf yield components can be important parameters in the selection of the cultivars best suited for specific uses, and in maximizing the production and processing efficiency of a selected kenaf crop. The objective of this research was to examine the yield components of five kenaf cultivarso A 2-yr study was conducted at Lane, OK, on a Bernow fine sandy loam, 0 to 3% slope, (fine-loamy, siliceous, thermic Glossic Paleudalf). Kenaf cultivars Tainung #2, Everglades 71, Everglades 41, Cuba 108, and Guatemala 51 were planted on 8 May 1989 and 23 May 1990. In each year plots were arranged in a randomized complete block design with four replications. Plots were hand harvested on 24 Oct. 1989 and 1990. Data collected included stalk and leaf yield, stalk and leaf percentage, bark and core percentage, bark to core ratio, stalk diameter, plant height, and plant population. Everglades 41 had the greatest percentage of stalk by weight (78.5%). Cuba 108 had the least percentage core material (62%), and the greatest bark to core ratio (0.61), while Tainung #2 had the greatest percentage core material (69%) and greatest plant height (299 cm). Tainung #2 also had greater stalk yields (13.8 Mg ha⁻¹) than either Guatemala 51 (11.4 Mg ha⁻¹) or Cuba 108 (10.8 Mg ha⁻¹).
