Technical Abstract: As the USA approaches commercial production of kenaf (Hibiscus cannabi L.) as an alternative fiber source for paper pulp and other uses, additional information is needed concerning kenaf varietal differences. Kenaf yield components can be important parameters in selecting the variety 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 determine the yield component differences among sixteen kenaf varieties. A 3-yr study was conducted at Lane, OK, during 1994, 1995, and 1996. Kenaf varieties Cuba 108, Cuba 2032, Cubano, Everglades 41, Everglades 71, GR-2563, Guatemala 4, Guatemala 45, Guatemala 48, Guatemala 51, India, KK60, Tainung #1, Tainung #2, 78-18GS-3 and 78-18RS-10 were planted in 30 inch rows on a Bernow fine sandy loam, 0 to 3% slope, (fine-loamy, siliceous, thermic Glossic Paleudalf). Each year plots were arranged in a randomized complete block design with four replications. Plots were hand harvested after 186, 164, and 163 days of growth. Data collected included stalk and leaf yield, stalk and leaf percentage, stalk diameter, plant height, and plant population. Stalk and leaf yields are based on oven-dried weights. Everglades 41, with a three year average of 91%, showed the greatest percentage of stalks by weight for two out of three years. Tainung #2 ranked first each year for stalk yields with a three year average of 9.7 t/a. India, in two out of three years, was the lowest ranking variety for stalk yields with a three year average yield of 4.9 t/a. Although the stalk yields for the sixteen varieties averaged 7.0 t/a during the 3-yr study, the ranking among most of the varieties varied a great deal from year to year.
