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 acúmulo de macro e micronutrientes da cultura do quiabeiro, no decorrer do ciclo, e obter equações que melhor os representem, um experimento foi realizado de 14 de janeiro a 14 de maio de 2009, na UNESP Câmpus de Jaboticabal, SP. A cv. Santa Cruz 47 foi semeada diretamente no sulco, em espaçamento de 1 x 0,2 m. No decorrer do ciclo, realizaramse coletas aleatórias de plantas com intervalos de quinze dias. As médias foram ajustadas às equações de regressão polinomial e de modelos não lineares. A partir de 50 dias após a semeadura (DAS) houve grande aumento no acúmulo de matéria seca nas partes da planta. Na colheita final, 120 DAS, as folhas, hastes e frutos representaram 21, 71 e 8%, respectivamente, da matéria seca total da planta. A seqüência decrescente de acúmulo 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
