Resumo: | The effects of four irrigation levels and two vermiculite treatments on the P, K, Mg, Ca and S uptake by rice (Oryza sativa L.) cultivars IAC 47, IRAT 13 and IET 1444 were measured in a greenhouse experiment using soil surface samples (0 cm -20 cm) of a Dark-Red Latosol (Haplusthox). The treatments included the irrigation levels corresponding to 55%, 70%, 85% and 100% of maximum evapotranspiration with and without vermiculite incorporation in the soil at 10% concentration on volume basis. The irrigation treatments were administered daily from the beginning of the reproductive phase until harvesting. The incorporation of vermiculite into the soil increased P, K and Mg uptake and decreased Ca. However, it did not affect S uptake. Water stress decreased P and K uptake but did not affect Mg, Ca and S. There were differences among the cultivars concerning nutrient uptake. The distribution of absorbed nutrients in the plant varied with water stress intensity, nutrient and cultivar. |

Utilizaram-se amostras da camada de 0 cm - 20 cm de um Latossolo Vermelho-Escuro. As diferentes lâminas d'água foram aplicadas diariamente, do início da fase reprodutiva até a colheita, e corresponderam a 55%, 70%, 85% e 100% da evapotranspiração máxima. A incorporação de vermiculita ao solo aumentou a absorção de P, K e Mg, diminuiu a de Ca e não afetou a de S. A deficiência hídrica não afetou a absorção de Mg, Ca e S, mas reduziu a de P e K. As cultivares estudadas diferiram quanto à absorção de nutrientes. A distribuição, na planta, dos nutrientes absorvidos, variou com a intensidade do estresse hídrico, com o nutriente considerado e com a cultivar.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraStone, Luis Fernando2014-04-16info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/16330Pesquisa Agropecuaria Brasileira; v.20, n.11, nov. 1985; 1251-1258Pesquisa Agropecuária Brasileira; v.20, n.11, nov. 1985; 1251-12581678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/16330/10547info:eu-repo/semantics/openAccess2014-04-16T19:38:14Zoai:ojs.seer.sct.embrapa.br:article/16330Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2014-04-16T19:38:14Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false |
