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 <

 . Additionally, lemongrass yielded 85.7 kg essential oil ha<

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