The harvesting was done twice (May - autumn and August - winter), and the leaves were separated for extraction of essential oil by Clevenger apparatus. The leaf production and oil content were calculated on dry mass basis. The results showed no statistical difference for organic fertilisation, although significant difference was verified for seasons. The main constituents of essential oil were eugenol and 1,8- cineole. The amount of the eugenol was higher in autumn, while the presence of other components including 1,8-cineole, beta-selinene and trans-caryophyllene were more dominant at wintertime.273-275engoil contenteugenol1,8-cineolebeta-selinenetrans-caryophylleneInfluence of organic fertilisation on leaves and essential oil production of Ocimum gratissimuim L.ArtigoWOS:000176890200040Acesso aberto43900736836105123541050909331364
