%X With the objective to quantify the okra crop¡¯s growth and macro and micronutrients accumulation during its life-cycle obtaining equations that best represent it, an experiment was carried out at Jaboticabal city, SP, Brazil, from January 14th to May 14th, 2009. The cv. Santa Cruz 47 was directly sowed into open soil furrows, in a spacing of 1 x 0,2 m. During the life-cycle were realized random samples of plants at 15 days intervals. The means were adjusted to polynomial regression equations set of non-linear parameters. After 50 days from sowing there has been a large increase of dry matter in plant¡¯ parts. At the final harvest, 120 days after sowing, the leaves, stems and fruits accounted for 21, 71 and 8%, respectively, from the total plant dry matter. The decreasing sequence of nutrient accumulation was K, Ca, N, Mg, P, Fe, B, Mn, Zn and Cu equivalent to 6,002.8; 4,733.8; 2,930.8; 1,196.3; 473.7; 436.2; 49.8; 10.4; 7.1; 7.1 e 1.5 mg plant-1. The quantity accumulated of culture were 146.5; 23.7; 300.1; 236.7; 59.8 e 21.8 kg ha-1 of N, P, K, Ca, Mg and S, respectively, and 520.0; 76.0; 2,491.0; 355.0 e 355.0 de B, Cu, Fe, Mn and Zn, respectively. Com o objetivo de quantificar o crescimento e o ac¨²mulo de macro e micronutrientes da cultura do quiabeiro, no decorrer do ciclo, e obter equa  es que melhor os representem, um experimento foi realizado de 14 de janeiro a 14 de maio de 2009, na UNESP Campus de Jaboticabal, SP. A cv. Santa Cruz 47 foi semeada diretamente no sulco, em espa amento de 1 x 0,2 m. No decorrer do ciclo, realizaramse coletas aleat¨®rias de plantas com intervalos de quinze dias. As m¨¦dias foram ajustadas ¨¤s equa  es de regress o polinomial e de modelos n o lineares. A partir de 50 dias ap¨®s a semeadura (DAS) houve grande aumento no ac¨²mulo de mat¨¦ria seca nas partes da planta. Na colheita final, 120 DAS, as folhas, hastes e frutos representaram 21, 71 e 8%, respectivamente, da mat¨¦ria seca total da planta. A seq¨¹¨ºncia decrescente de ac¨²mulo de nutrientes pelo quiabeiro foi K, Ca, N, Mg, P, S, Fe, B, Mn, Zn e Cu, o equivalente a 6.002,8; 4.733,8; 2.930,8; 1.196,3; 473,7; 436,2; 49,82; 10,4; 7,1; 7,1 e 1,52 mg planta-1. As quantidades acumuladas pela cultura foram 146,5; 23,7; 300,1; 236,7; 59,8 e 21,8 kg ha-1 de N, P, K, Ca, Mg e S, respectivamente, e de 520,0; 76,0; 2.491,0; 355,0 e 355,0 g ha-1 de B, Cu, Fe, Mn e Zn, respectivamente.
