Resumo: | With the objective of evaluating the isolated and combined effects of terminal bud removal and debudding in uplan cotton (Gossypium hirsutum L.r. latifolium Hutch.), cv. CNPA Precoce 1, a field experiment was conducted during the rainy season of 1986 and repeated in 1987 at Sousa, PB, Brazil. In 1986, in a nonfertilized soil it was verified that bud removal realized after fifty days of plant emergence, increased the earlyness in 6.7%, reduced plant height by 16.2%, but did not alter stem diameter and cotton yield. The flower bud removal during the first 28 days after budding start, reduced cotton yield by 23.7% and earlyness from 78.0 tu 29.6%. In 1987, with fertilized soil, the terminal bud removal did not reduce yield, earlyness, and stem diameter but reduced plant height by 31.9%. Flower bud removal reduced earlyness from 50.5 to 22.9% and did not reduce yield |

Verificou-se, em 1986, em solo não adubado, que a retirada da gema apical aumentou a precocidade em 6,7%, reduziu a altura da planta em 16,2% e não alterou o diâmetro do caule nem a produtividade. Observou-se que com a remoção dos botões florais durante os primeiros 28 dias da fase reprodutiva, houve redução de 23,7% na produtividade, e a precocidade passou de 78,0% para apenas 29,6%. Em 1987, com a aplicação de sulfato de amônio verificou-se que a remoção da gema apical não alterou a produtividade, o diâmetro caulinar nem a precocidade das plantas, mas reduziu a altura das plantas em 3 1,9%. A remoção dos botões florais descreveu a precocidade de 50,5% para 22,9% e não alterou a produtividade da culturaPesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraBeltrão, Napoleão Esberard de MacêdoNóbrega, Laudomiro Baldoíno daVieira, Dirceu JustinianoAzevêdo, Demóstenes Marcos Pedrosa deSousa, Roberto Pequeno de2014-04-17info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/13551Pesquisa Agropecuaria Brasileira; v.25, n.7, jul. 1990; 1047-1054Pesquisa Agropecuária Brasileira; v.25, n.7, jul. 1990; 1047-10541678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/13551/7695info:eu-repo/semantics/openAccess2014-04-17T14:34:50Zoai:ojs.seer.sct.embrapa.br:article/13551Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2014-04-17T14:34:50Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false |
