Kenaf ( Hibiscus cannabinus L.) is being investigated as a prospective new annual paper pulp crop. ‘Everglades 71’ and ‘Guatemala 4’ kenaf were grown in 50‐cm rows to study the effect of plant densities of 6.6, 8.8, 13.2, and 26.2 plants/m 2 on stem yield, stem diameter, and plant height. Stem yield of Everglades 71 was higher in 1 of 3 years, but with 3‐year averages, varieties did not differ in any characteristic studied. Stem yield at 26.2 plants/m 2 was higher than at other densities in 1 of 3 years. Basal stem diameter decreased as plant density increased, but plant height was not affected. The results of this experiment indicate that to avoid excessive plant branching at low densities and lodging of small plants at high densities, an intermediate plant density might be preferable.
