Resumo: Forty eight upland rice (Oryza sativa L.) cultivars were evaluated for their response to lime in a greenhouse experiment using a Dark-Red Latosol. Based on a calibration curve, four levels of lime were applied (0, 9, 18 27 g/pot-lime neutralizing value 100%). These lime levels correspond to 1; 2.7; 4.2 and 5.4 meq/100 g of Ca + Mg in the soil. Yield increase for each cultivar was calculated at 9, 18 and 27g lime treatments in relation to production at no lime treatment. Rice cultivars responded to lime application and the response varied from cultivar to cultivar. Based on this yield increase, cultivars were classified in three groups as low, medium and highly responsive to lime application. Among tested cultivars, IAC 47 and CNA 104-B-68-B-2 were more productive at low as well as higher levels of Ca + Mg.

Com base na curva de calibração, foram aplicados quatro níveis de calcário (0, 9, 18, 27 g/vaso - PRNT 100%), que resultaram, respectivamente, em 1; 2,7; 4,2 e 5,4 meq/100 g de Ca + Mg do solo. De acordo com as respostas aos níveis de calcário aplicados, as cultivares foram classificadas em três grupos: baixa, média e altamente responsivas à aplicação de calcário. Entre as mais produtivas em condições de baixos níveis de Ca + Mg e mais responsivas ao calcário sobressaíram a IAC 47 e a CNA 104-B-68-B-2.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraFageria, Nand KumarMorais, Orlando Peixoto2014-04-17info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/14926Pesquisa Agropecuaria Brasileira; v.22, n.7, jul. 1987; 667-672Pesquisa Agropecuária Brasileira; v.22, n.7, jul. 1987; 667-6721678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/14926/8629info:eu-repo/semantics/openAccess2014-10-08T17:54:03Zoai:ojs.seer.sct.embrapa.br:article/14926Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2014-10-08T17:54:03Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
