Resumo: Soybean (Glycine max (L.) Merrill) is known to have a high ability as a potassium extractor, and different cultivars show different potassium requirements. An experiment was run to study the potassium nutrition of soybean as related to plant characteristics. Six soybean cultivars (FT-2, Bossier, IAC-11, IAC-17, IAC-18 and IAC-19) were grown in 6 kg pots filled with the topsoil of a Dark Red Latosol (sandy loam), either with and without K fertilization. The plants were harvested 70 days after emergence. Soybean response to potassium was not related to growth habit or group of maturation. There was a different response to K. The cultivars IAC-18 and FT-2 were less tolerant to K deficiency. Potassium deficiency in the leaves was not related to top dry matter production. With K fertilization soybean plants showed small root volume and higher ratio canopy/root. With high K in soil, all of the cultivars showed higher nodulation.

Merrill) apresenta grande capacidade de exploração do potássio no solo. Além disso, diferentes cultivares apresentam exigências diferentes em potássio. O objetivo deste trabalho foi estudar o comportamento de seis cultivares de soja quanto à nutrição potássica, relacionando-a aos parâmetros de crescimento. O experimento foi instalado em vasos de 6 kg de terra proveniente de um Latossolo Vermelho-Escuro de textura média, em casa de vegetação. As cultivares utilizadas foram: FT-2, Bossier, IAC- 11, IAC- 17, IAC- 18 e IAC- 19, em presença ou ausência de adubação potássica. A coleta das plantas foi realizada aos 70 dias após a emergência. A resposta da soja ao potássio aplicado não esteve relacionada ao hábito de crescimento ou ciclo das plantas. Houve diferentes respostas das cultivares ao potássio, sendo que 'IAC- 18' e 'FT-2' foram as mais prejudicadas pela falta de aplicação do nutriente. A ocorrência e a intensidade dos sintomas de deficiência de potássio não estiveram relacionadas à produção de matéria seca da parte aérea da planta. Com a aplicação de potássio ao solo, as plantas apresentaram menor peso e menor volume de raizes, e maior relação parte aérea/raiz, em peso. Plantas bem nutridas com potássio apresentaram maior peso de matéria seca de nódulos.UNIV ESTADUAL PAULISTA JULIO MESQUITA FILHO,DEP AGR & MELHORAMENTO VEGETAL,FCA,CAIXA POSTAL 237,BR-18603970 BOTUCATU,SP,BRAZILUNIV ESTADUAL PAULISTA JULIO MESQUITA FILHO,DEP AGR & MELHORAMENTO VEGETAL,FCA,CAIXA POSTAL 237,BR-18603970 BOTUCATU,SP,BRAZILEmpresa Brasileira de Pesquisa Agropecuária (EMBRAPA)Universidade Estadual Paulista (Unesp)Rossetto, CAVFernandes, Dirceu Maximino [UNESP]Ishimura, IRosolem, Ciro Antonio [UNESP]2014-05-20T15:27:53Z2014-05-20T15:27:53Z1995-10-01info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/article1225-1231application/pdfhttp://seer.sct.embrapa.br/index.php/pab/article/view/4418Pesquisa Agropecuaria Brasileira.
