Plants producing essential oils are influenced by various factors that may affect the amount and chemical composition of the oil. The lemon grass (Cymbopogon citratus) despite being widely used in Brazil has a limited number of studies on the production of essential oil. Its essential oil is highly sought by industry of cosmetics, perfumes and drugs. The challenge for those who cultivate the plants producing essential oils is to know the factors that influence the composition and quantity of oil. The aim of this study was to evaluate the effect of leaf collection schedule on the content of essential oil of lemon grass. The experimental design was a randomized block with three installments, with the treatment the following times cutting: 8:00, 12:00, 16:00, 20:00, 24:00, 04:00 hours. It was found that the leaves of the crop lemon grass should be avoided at noon hours (12:00 hours), for providing the lowest level of the essential oil.
