Resumo: The  objective  of  this  work  was  to  assess stalk  and sugar  yield,  water  use  efficiency,  and technological attributes of five early maturing and six medium to late maturing sugarcane varieties with no irrigation (1,141.4 mm) and under full irrigation (1,396.6 mm). A randomized complete block design, with four replicates, was used. Stalk yield for varieties RB92579, RB72454, and SP81-3250 showed gains above 180% with irrigation. Irrigation increased sugar yield in more than 200% in the RB92579 and RB943365 varieties. Full irrigation provided greater water use efficiency, producing, in average, 70.2 kg ha-1 mm-1 more stalks than under no irrigation. Except for the varieties RB72454, RB763710, and RB943365, there were no differences regarding technological attributes between full irrigation and no irrigation. The medium to late maturing varieties RB92579 and SP81‑3250 have higher stalk and sugar yield and better water use efficiency, and are recommended for studies on sugarcane response to irrigation.

A produtividade de colmos das variedades RB92579, RB72454 e SP81-3250 apresentou ganhos superiores a 180%, com uso da irrigação. A irrigação promoveu aumentos na produtividade de açúcar superiores a 200%, nas variedades RB92579 e RB943365. A irrigação plena proporcionou maior eficiência de uso da água, com produção média de 70,2 kg ha-1 mm-1 de colmos a mais em comparação ao regime de sequeiro. Com exceção das variedades RB72454, RB763710 e RB943365, não houve diferença nos atributos tecnológicos entre a irrigação plena e o regime de sequeiro. As variedades RB92579 e SP81-3250 de maturação média à tardia se destacam quanto à produtividade de colmos e de açúcar e à eficiência de uso da água, e são recomendadas para estudos de resposta à irrigação pela cana-de-açúcar.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraUFRPEUFRPEde Oliveira, Emídio Cantídio AlmeidaFreire, Fernando Joséde Oliveira, Alexandre CampeloSimões Neto, Djalma Euzébioda Rocha, Alexandre Tavaresde Carvalho, Laércio Alves2011-08-15info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/10222Pesquisa Agropecuaria Brasileira; v.46, n.6, jun. 2011; 617-625Pesquisa Agropecuária Brasileira; v.46, n.6, jun. 2011; 617-6251678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/10222/6388https://seer.sct.embrapa.br/index.php/pab/article/downloadSuppFile/10222/5543https://seer.sct.embrapa.br/index.php/pab/article/downloadSuppFile/10222/6454https://seer.sct.embrapa.br/index.php/pab/article/downloadSuppFile/10222/6455info:eu-repo/semantics/openAccess2014-05-30T16:54:00Zoai:ojs.seer.sct.embrapa.br:article/10222Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2014-05-30T16:54Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
