“…Some research has been done to develop improved management practices for kenaf yield, but these studies were located in only a few U.S. regions. Studies have focused on management practices, such as planting time, row spacing, population density, fertilization, irrigation, or crop rotation practices in Florida (Joyner & Wilson, 1967), Nebraska (Williams, 1966), California (Bhangoo, Tehrani, & Henderson, 1986), Mississippi (Baldwin & Graham, 2006), Maryland (Campbell & White, 1982; Massey, 1974), New Mexico (Lauriault & Puppala, 2009), and North Carolina (Jordan et al., 2005). Numerous studies on kenaf management have been done outside the United States, that is, Spain (Manzanares, Tenorio, & Ayerbe, 1997; Moreno et al., 2004; Wood, Muchow, & Ratcliff, 1983), Italy (Mambelli & Grandi, 1995), Greece (Alexopoulou, Christou, Mardikis, & Chatziathanassiou, 2000; Danalatos & Archontoulis, 2010), and Australia (Carberry et al., 1992; Muchow & Carberry, 1993).…”

The demand for natural fibers is increasing worldwide as markets respond to the need to replace nonrenewable sources. Kenaf (Hibiscus cannabinus L.) is a promising biorenewable resource for producing natural fibers. Few studies have investigated the crop when grown at latitudes above 40 • and in the U.S. Midwest. The objectives of this study were to assess the influence of management practices on fiber (bast and core lignocellulose) composition, carbon (C), nitrogen (N), and total ash concentration. Cultivars 'Tainung 2' and 'Whitten' were planted in Boone County, IA in 2014 and 2015 at 247,000 or 371,000 seed ha −1 , in 38-or 76-cm rows, and fertilized with N at 0, 56, 112, 168, or 224 kg ha −1 . Treatments were in a factorial design with four replications in 2 yr. Stem bast and core lignocellulose concentrations, total ash, and C/N ratio were determined at harvest. Variety or interactions of variety with management practices influenced most parameters. Increased N fertilization decreased bast cellulose concentration, but increased core cellulose concentration. Hemicellulose concentration in core was greater than in bast. Ash concentration decreased as N fertilization rate increased and interacted with seeding rate and variety. The implications of these observations are directly related to markets and desired kenaf end-use products. Variety and management interactions influence kenaf fiber quality, and consequently are important considerations for kenaf producers and processors.Abbreviations: ADF, acid detergent fiber; ADL, acid detergent lignin; DM, dry matter; NDF, neutral detergent fiber.

“…Optimal management practices have been studies for kenaf yield in the United States, but primarily results are from southern states. Studies have focused on management practices, such as planting time, row spacing, population density, fertilization, irrigation, or crop rotation practices in Florida (Joyner and Wilson, 1967), Nebraska (Williams, 1966), California (Bhangoo et al, 1986), Mississippi (Baldwin and Graham, 2006), Maryland (Massey, 1974; Campbell and White, 1982), New Mexico (Lauriault and Puppala, 2009), and North Carolina (Jordan et al, 2005). Numerous studies on kenaf management were conducted outside of the United States, that is, Spain (Manzanares et al, 1997; González Moreno et al, 2004; Wood et al, 1983), Italy (Mambelli and Grandi, 1995), Greece (Alexopoulou et al, 2000; Danalatos and Archontoulis, 2010), and Australia (Carberry et al, 1992; Muchow and Carberry, 1993).…”

Core Ideas Two kenaf cultivars were compared for stem fiber yield under combinations of planting rate, row spacing, and N fertilization rate. Tainung 2 produced greater stem fiber yield than Whitten. Nitrogen fertilization rate did not influence stem fiber yield. Stand density, core/bast fiber ratio, and basal stem diameter were influenced by three‐way interactions. ABSTRACT Kenaf (Hibiscus cannabinus L.) is a promising biorenewable resource for producing natural fibers but few studies have investigated the crop when grown in cooler climates, such as the American Midwest. The objectives of this study were to: (i) determine the agricultural practices (row spacing, seed, and N rates) leading to optimal kenaf dry matter (DM) stem and fiber yield in cultivars Tainung 2 and Whitten; (ii) evaluate stem height, basal diameter, and leaf area index (LAI) over the growing season; and (iii) assess the influence of management practices on fiber (bast and core lignocellulose) composition, and–2C, N, and total ash concentration. Kenaf cultivars Tainung 2 and Whitten were planted in Boone County, Iowa,–2in 2014 and 2015 at 247,000 or 371,000 seed ha−1, in 38‐cm or 76‐cm rows that received 0, 56, 112, 168, or 224 kg N ha−1. Stand density, core:bast fiber ratio, and basal stem diameter were influenced by three‐way interactions. Stem height at harvest was influenced by the main effects of row spacing, seeding rate, and N fertilization rate. Nitrogen fertilization did not influence stem DM yield, regardless of application rate. Kenaf is a promising multi‐purpose crop that could contribute to the natural fiber marker, as well as diversifying the landscape. Kenaf is well adapted to Iowa and can be produced with a range of management practices.

professionalism, efficiency, hard-work, ingenuity, and reliability. Many memories stay in my mind and I am going to miss mowing the farm with Roger's tractors. My project would not have been possible without them and I owe them so much. I think they do not always receive the credit they really deserve, and one of my regrets was to help them as much as they helped me in the lab or in the fields. Fourth, I would like to thank my friends, office mates, the Department faculty and staff, and the Agronomy Graduate Student Club for making my time at Iowa State University a wonderful experience. The diversity of personality, experience, and culture was such a personal enrichment. I enjoyed participating in the social events within the Department and I have built some tight relationships that, I hope, will last for a long time:
