Interpretive Summary: Research has indicated that kenaf is moderately salt tolerant. Since soils of the westside of the San Joaquin Valley are often high in salinity, six kenaf varieties and five USDA-ARS kenaf strains were grown on both saline and nonsaline soils to determine the production potential of the new strains and selected varieties on the two soils types and to evaluate salt tolerance capacity of these new strains and selected kenaf varieties. Dry stem yield varied from 4.2 to 6.2 tons and 7.3 to 9.2 tons per acre on the saline and the nonsaline soil, respectively, with yields being significantly reduced by salinity. Reductions in stem yields due to soil salinity was lowest for Iran Early Best-726, Indian, KU482, and C725-92; intermediate for Tainung 1, C531-92, C624-92, and Everglades 71; and greatest for C533-92, Everglades 41, and C320-92. Averaged across the two soil types, yields were highest for C531-92 and Everglades 71, which were intermediate in rank for salt tolerance.

Technical Abstract: The soils of the westside of the San Joaquin Valley are often high in salinity, which reduces the number of crops that can be grown, as well as crop yields. Six varieties of kenaf and five USDA-ARS kenaf strains were grown on a saline and nonsaline soil to determine the production potential of the new strains and selected varieties on a saline and nonsaline soil irrigated with good quality water, and to evaluate salt tolerance capacity of these new strains and selected kenaf varieties. Dry stem yields varied from 4.2 to 6.2 tons and 7.3 to 9.2 tons per acre on the saline and the nonsaline soil, respectively. The decrease in stem yields due to soil salinity was lowest for Iran Early Best-726, Indian, KU482, and C725-92; intermediate for Tainung 1, C531-92, C624-92, and Everglades 71; and the greatest for C533-92, Everglades 41, and C320-92. Averaged across the two soil types, yields were highest for C531-92 and Everglades 71, which were intermediate in rank for salt tolerance.
