%X Mentha x piperita L. is an aromatic and medicinal species belonging to the family Lamiaceae that is popularly known as peppermint. The aim of this study was to evaluate the effects of organic fertilizer sources on the biomass production, yield and chemical composition of peppermint (Mentha piperita L.) essential oil. The experiment was conducted using a completely randomized design (CRD) with a 2 x 5 factorial scheme, two sources of manure (cattle and poultry), five doses (0, 3, 6, 9 and 12 kg m-2) and four replicates. Different doses of cattle and poultry manure significantly affected plant biomass production and the responses of other variables, including leaf area, leaf weight ratio, leaf area ratio, root:shoot ratio, yield and chemical composition. Organic fertilizer doses of 9.0 kg m-2 cattle manure and 8.3 kg m-2 poultry manure to obtain the maximum total dry biomass. The highest yield of essential oil was obtained by applying 11.8 kg m-2 poultry manure. Differences in the chemical composition of the essential oil were observed for only three components (menthone, pulegone and menthyl acetate) without significant changes in the menthol content. Mentha x piperita L. ¨¦ uma planta arom¨¢tica e medicinal pertencente ¨¤ fam¨ªlia Lamiaceae, popularmente conhecida como hortel -pimenta. No trabalho, objetivou-se verificar o efeito das fontes de aduba  o organica na produ  o de biomassa, no rendimento e na composi  o qu¨ªmica do ¨®leo essencial de hortel -pimenta (Mentha piperita L.). O experimento foi conduzido em DIC, em esquema fatorial 2 x 5, com duas fontes de esterco, bovino e av¨ªcola, e cinco doses (0, 3, 6, 9 e 12 kg m-2), com quatro repeti  es cada. As diferentes doses de estercos bovino e av¨ªcola influenciaram significativamente de forma ben¨¦fica a produ  o de biomassa das plantas e tamb¨¦m outras vari¨¢veis de crescimento como ¨¢rea foliar, raz o de peso foliar, raz o de ¨¢rea foliar, rela  o raiz:parte a¨¦rea, rendimento e composi  o qu¨ªmica do ¨®leo de hortel -pimenta. Utilizar aduba  o organica para a obten  o m¨¢xima de biomassa seca total as doses de 9,0 kg m-2 de esterco bovino e 8,3 kg m-2 de esterco av¨ªcola. O maior rendimento de ¨®leo ¨¦ obtido com a aplica  o de 11,8 kg m-2 de esterco av¨ªcola. Diferen as na composi  o qu¨ªmica do ¨®leo essencial foram observadas para tr¨ºs componentes (mentona, pulegona e acetato de mentila) sem mudan a significativa no conte¨²do de mentol.
