Resumo: The objective of this work was to assess different pruning dates on the development, production and quality of cassava roots. Two experiments were carried out in two regions of the state of São Paulo, Brazil: Botucatu, on clay soil, and São Manuel, on sandy soil. The experiments were carried out from September 2008 to June 2010, and harvest was done after two growing seasons (22 months). The experimental design was a randomized block design, with four replicates. Ten treatments, nine monthly pruning dates, between April and December, and a control cultivated without pruning were evaluated. Pruning dates were statistically analyzed by orthogonal contrasts, in comparison to the control, and by regression. Cassava pruning during the rest period does not alter dry matter content and root yield. However, when performed at the end of the first cycle or after the start of the second cycle, pruning reduces dry matter content and root yield.

Foram conduzidos dois experimentos, em duas localidades do Estado de São Paulo: Botucatu, em área de solo argiloso, e São Manuel, em solo arenoso. Os experimentos foram conduzidos de setembro de 2008 a junho de 2010, e a colheita foi feita após dois ciclos vegetativos (22 meses). Utilizou-se o delineamento experimental de blocos ao acaso, com quatro repetições. Foram avaliados dez tratamentos, nove épocas de poda espaçadas mensalmente, entre abril e dezembro, e uma testemunha conduzida sem poda. As épocas de poda foram analisadas estatisticamente por contrastes ortogonais, em comparação à testemunha, e por regressão. A poda da mandioca realizada no período de repouso fisiológico não altera o teor de matéria seca e a produtividade de raízes tuberosas. No entanto, quando realizada no final do primeiro ciclo ou após o início do segundo ciclo vegetativo, a poda reduz o teor de matéria seca e a produtividade de raízes.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraCAPESAguiar, Eduardo BarretoBicudo, Silvio JoséCurcelli, FelipeFigueiredo, Priscila GonzalesCruz, Simério Carlos Silva2012-02-09info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/10747Pesquisa Agropecuaria Brasileira; v.46, n.11, nov. 2011; 1463-1470Pesquisa Agropecuária Brasileira; v.46, n.11, nov. 2011; 1463-14701678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/10747/6694https://seer.sct.embrapa.br/index.php/pab/article/downloadSuppFile/10747/6158https://seer.sct.embrapa.br/index.php/pab/article/downloadSuppFile/10747/6159info:eu-repo/semantics/openAccess2014-05-09T17:29:30Zoai:ojs.seer.sct.embrapa.br:article/10747Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2014-05-09T17:29:30Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
