Abstract in Portuguese
Para determinação do efeito de nutrientes na qualidade do óleo essencial da Mentha arvensis, cultivou-se plantas submetidas a oito tratamentos em solução nutritiva completa, com omissão de nitrogênio, fósforo, potássio, cálcio, ferro, zinco e boro. O óleo essencial das folhas de cada tratamento foi extraído por destilação de arraste de vapor e analisado por cromatógrafo acoplado a espectrômetro de massa (GCMS). A análise indicou sensíveis diferenças quanto ao número de componentes e à proporção de limoneno, mentora, mentol e metil acetato no óleo. Determinou-se também efeitos da omissão de nutrientes no desenvolvimento de folhas, hastes, estolões e raízes das plantas e as suas respectivas extrações de nutrientes. Sintomas visuais de deficiência de nitrogênio, fósforo, potássio e cálcio foram observados e descritos

Abstract in English
To determinate the effect of the macro and micronutrients on the Mentha arvensis essentiaI oil, plants were submitted to complete nutrient solution or without N, P, K., Ca, Fe, Zn and B. EssentiaI oil extracted by hydrodestillation was anaIyzed by gas chromatography and mass spectrometry. Oil nutrient omission intluenced oil quality affecting concentrations of limonene, menthone, menthol and menthyl acetate. Nutrient omission aItered leaves, shoots, rhizomes and roots development as their respective nutrient extraction. This work aIso describes visual symptoms of nitrogen, phosphorous, potassium and calcium deficiencies
