Technical Abstract: Research information is limited concerning the affect of soil moisture, fertility, and cultivar interactions on kenaf (Hibiscus cannabinus L.) yield components. The objective of this two year research study in Oklahoma was to investigate the interaction of these factors on kenaf development and yields. The factorial design involved two levels of irrigation (irrigated and non-irrigated), five levels of nitrogen fertilization (0, 57, 114, 171 and 228 kg/ha), and two cultivars (Tainung #2 and Everglades 41). Drip irrigation was used to supply water to the irrigated treatments and the fertilizer was manually spread prior to planting. Plant populations were unaffected by the irrigation treatments, though additional water did increased plant height, development, stalk percentage, and stalk yields across all other factors. Tainung #2, a deeply divided leaf cultivar, had greater yield components than Everglades 41, entire leaf cultivar. The yield components for both cultivars were adversely affected by nitrogen applications greater than 114 kg/ha.
