Resumo: The objective of this work was to evaluate the effects of soil pH on yield and its components and nutrients uptake by three upland rice cultivars/lines in a Dark-Red Latosol, clay loam texture of Cerrado region. A greenhouse experiment was conducted at the Embrapa-Centro Nacional de Pesquisa de Arroz e Feijão, Santo Antônio de Goiás, GO, Brazil. Soil pH levels created by application of lime were 4.6, 5.7, 6.2, 6.4, 6.6, and 6.8 and cultivars/lines tested were CNA 7460, Araguaia and CNA 7449. Dry matter and grain yield and yield components and nutrient absorption were significantly affected with soil pH. Adequate soil pH for yield and yield components was in the range of 5 to 5.4 and for the nutrients 4.6 to 5.5. These results suggest that rice cultivars tested were quite tolerant to soil acidity and it is possible to produce satisfactory crop in the pH range of 5 to 5.5.

O experimento foi conduzido sob condições de casa de vegetação, na Embrapa-Centro Nacional de Pesquisa de Arroz e Feijão, em Santo Antônio de Goiás, GO. Os níveis de pH criados, pela aplicação de calcário, foram: 4,6, 5,7, 6,2, 6,4, 6,6 e 6,8. Testaram-se as cultivares/linhagens de arroz de terras altas CNA 7460, Araguaia e CNA 7449. A produção de matéria seca e de grãos, os componentes de produção e a absorção de nutrientes foram significativamente influenciados pelo pH do solo. A faixa com pH adequado para a produção e para os componentes de produção variou entre 5 e 5,4. Da mesma maneira, para absorção de nutrientes, a variação foi de 4,6 a 5,5, indicando que as cultivares de arroz de terras altas avaliadas são bastante tolerantes à acidez do solo, produzindo satisfatoriamente sob pH entre 5 e 5,5.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraFageria, Nand Kumar2000-11-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/6025Pesquisa Agropecuaria Brasileira; v.35, n.11, nov. 2000; 2303-2307Pesquisa Agropecuária Brasileira; v.35, n.11, nov. 2000; 2303-23071678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/6025/3129info:eu-repo/semantics/openAccess2014-08-20T18:22:32Zoai:ojs.seer.sct.embrapa.br:article/6025Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2014-08-20T18:22:32Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
