Summary

Hesperaloe funifera (Agavaceae) is an experimental fibre crop which produces strong, fine fibres with potential uses in the specialty-paper industry. Hesperaloe's agronomic potential was evaluated in two long-term studies. The plant is a perennial with a rosette habit. Growth occurred by production of new leaves from the primary rosette until Year 3 and from secondary rosettes from Year 3 on. Rates of biomass growth increased over the five years studied. High-density stands (27 000 plants ha-l) produced 190 t fresh weight ha-1 after five years. Plots harvested once, after Year 5, produced more biomass than plots harvested twice, after Years 3 and 5. Increased biomass production can be achieved by improved stand establishment and nutrient management.
