Resumo: The different response of 100 rice (Oryza sativa L.) cultivars to liming was assessed in a greenhouse experiment using a Dark-Red-Latosol. A calibration curve was developed using different lime levels to get a range of Ca + Mg in the soil. With the help of this calibration curve, three levels of lime were applied (0, 10, 30 g per pot) corresponding to 0.6, 2.5 and 4.9 meq/100 g of Ca + Mg in the soil. Rice cultivars responded to lime application but response varied from cultivar to cultivar. The average response of 100 cultivars was determined. An increase of 23% in grain production was obtained at 30 g lime per pot as compared with no lime treatment. Yield increase for each cultivar was also calculated at 10 and 30 g lime treatments in relation to production at no lime. Based on this yield increase, cultivars were classified in three groups as low, medium and highly responsive to application of calcium and magnesium in the soil. Effect of lime on chemical properties of soil is discussed.

Foi desenvolvida uma curva de calibração, com aplicação de vários níveis de calcário, para obter uma faixa de Ca + Mg no solo. Com a ajuda desta curva de calibração, foram aplicados três níveis de calcário (0, 10 e 30 g por vaso), que correspondem a 0,6; 2,5 e 4,9 de Ca + Mg meq/100 g no solo. As respostas das cultivares à aplicação de calcário variaram de cultivar para cultivar. Foi calculada uma resposta média de 100 cultivares, registrando-se um aumento de, aproximadamente, 23% na produção de grãos, com a aplicação de 30 g de calcário por vaso, em comparação ao tratamento sem calcário. O aumento da produção de cada cultivar também foi calculado sob os tratamentos de 10 e 30 g de calcário (correspondente a 2,5 e 4,9 meq/100 g de Ca + Mg no solo) em relação ao sem calcário. Com base neste aumento, as cultivares foram classificadas em três grupos: baixa, média e altamente responsivas à aplicação de calcário no solo. Foi discutido o efeito da aplicação de calcário sobre as propriedades químicas do solo.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraFageria, Nand Kumar2014-04-16info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/15964Pesquisa Agropecuaria Brasileira; v.19, n.7, jul. 1984; 883-889Pesquisa Agropecuária Brasileira; v.19, n.7, jul. 1984; 883-8891678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/15964/10072info:eu-repo/semantics/openAccess2014-04-16T19:26:03Zoai:ojs.seer.sct.embrapa.br:article/15964Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2014-04-16T19:26:03Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
