 Cymbopogon flexuosus<

 , palmarosa, are perennial grasses grown to produce essential oils for the fragrance industry. The objectives of this study were (1) to evaluate biomass and oil yields as a function of nitrogen and sulfur fertilization, and (2) to characterize their utility for lignocellulosic ethanol compared to <

  during the second harvest year resulting in theoretical biofuel yields of 2541 and 2569 L ethanol ha<

 . In conclusion, these data suggest that dual-use crops such as lemongrass and palmarosa may increase the economic viability of lignocellulosic biofuels. Introduction
