%X Estudou-se o efeito da aplica  o de tr那s doses N, P e K em substratos sobre o estado nutritional de porta-enxertos de limoeiro 'Citrumelo' (Citrus paradisi x Poncirus trifoliata). O experimento obedeceu ao delineamento estat赤stico inteiramente casualizados em esquema fatorial 3x3 + 1 (tr那s nutrientes x tr那s doses + urna testemunha) com 3 repeti  es. Os tratamentos foram constituidos por: T)x = metade da dose padr o; D2 = a dose padr o; e, D3 = duas vezes a dose padr o, al谷m da testemunha (sem aduba  o). Aos quatro meses ap車s a emerg那ncia dos porta-enxertos do limoeiro 'Citrumelo' as plantas foram submetidas a determina  o do teor e acumulo dos nutrientes. A an芍lise dos resultados revelou que plantas de limoeiro 'Citrumelo' 'Swingle' s o responsivas a aplica  o de N, P e K. A aplica  o de nitrog那nio afetou de forma linear o acumulo de N e K; j芍 as aplica  es de f車sforo e pot芍ssio proporcionaram efeito quadr芍tico no acumulo de P e K, respectivamente. The effect of the application of three doses N, P and K on substrates on the nutritional status of root stock of 'Citrumelo' lemon (Citrus paradisi x Poncirus trifoliata) was evaluated. The experiment followed a fully randomized factorial design (3x3) (three nutrients x three doses plus a control) with three replicates. The treatments consisted of Dl = half standard dose, D2 = one standard dose and D3 = twice standard dose, in addition to the control that did not received fertilization at all. At four months after the emergence of the root stock of lemon 'Citrumelo' the plants tissue (leaves) were determined for nutrients analysis to obtain its accumulation. The results showed that plants of lemon 'Citrumelo' 'Swingle' are responsive to the application of N, P and K. The application of nitrogen showed a linear accumulation pattern of N and K, while the applications of phosphorus and potassium provided a quadratic response.
