ResumoCom 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 sequência 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
AbstractWith 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 14 th to May 14 th , 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.
