The objective of this work was to evaluate the effect of cut-time on lemon grass essential oil yield and on its constituent citral contents. A completely randomized design with four replications was used. Six cuttimes were studied: 7:00, 9:00 and 11:00 AM, 1:00, 3:00 and 5:00 PM. The analyzed variables were essential oil yield and relative citral contents. The highest essential oil yield was obtained when cut occurred at 7:00 AM. The highest citral contents was obtained when cut occurred at 1:00 PM, but was not statistically different from those obtained at 7:00, 9:00 and 11:00 AM, and 3:00 PM. Lemon-grass must be harvested between 9:00 and 11:00 AM in order to obtain maximum essential oil yield and maximum citral contents.
