• Resumo:

  The effects of organic fertilization and cutting height on dry matter and essential oil production from leaves of Lippia alba, limonene-carvone chemotype, were evaluated in the Northeastern Brazilian Region. A split plot experiment was conducted with the organic fertilization (0; 2 and 4 kg m-2) as main plots and 15; 30 and 45 cm cutting height as subplots. First harvest was done 60 days and the second 120 days after planting date. Dry matter and essential oil production were not influenced by fertilization. Highest dry matter production was observed on 45 cm cutting height. Highest essential oil production was obtained on 30 and 45 cm cutting height.
