Resumo: | The cultivation of flooded rice (Oryza sativa L.) ratoon crop may constitute a profitable activity, if an adequate water management is adapted. The objective of this study was to determine the effects of drainage and irrigation periods, before and after, respectively, main crop harvest on the performance of flooded rice main and ratoon crop. Treatments consisted of the combination of four drainage periods (0, 10, 20, and 30 days) before the main crop harvest with the introduction of irrigation at 0, 10, 20, and 30 days after the main crop harvest. The experimental design was a randomized complete block in a 4x4 factorial scheme, with four replication. The rice ratoon crop performance was differently affected by the irrigation periods after main crop harvest according to environmental conditions. Retardation in flooding decreased grain yield and grain quality, when air temperatures unsuitable to ratoon crop development occurred. Under suitable air temperatures conditions, starting flooding at nine days after the main crop harvest was the best treatment to the performance of ratoon crop, which represented 14% of saved irrigation water. Rice ratoon crop apparently is not favorable to the development of Oryzophagus oryzae harmful population. |

O objetivo deste estudo foi determinar os efeitos de períodos de drenagem e de irrigação, antes e depois, respectivamente, da colheita da cultura principal sobre o comportamento da cultura principal e da soca de arroz. Os tratamentos consistiram da combinação de quatro períodos de drenagem (corte da irrigação e abertura dos drenos aos 0, 10, 20 e 30 dias) antes da colheita da cultura principal, com o reinício da irrigação aos 0, 10, 20 e 30 dias após a colheita da cultura principal, em arranjo fatorial 4x4, no delineamento experimental de blocos ao acaso, com quatro repetições. Os períodos de irrigação após a colheita afetaram diferentemente o comportamento da soca de arroz de acordo com as condições climáticas. Com temperaturas do ar mais baixas, o atraso no reinício da irrigação reduziu a produtividade e a qualidade do produto colhido. Em condições climáticas de temperaturas do ar mais altas, a inundação iniciada nove dias após a colheita da cultura principal resultou em melhor desempenho da soca, com uma economia de água de 14% em relação à inundação imediatamente após a colheita. A soca aparentemente não se apresenta favorável ao desenvolvimento de populações daninhas de larvas da bicheira-da-raiz do arroz, Oryzophagus oryzae.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária Brasileirados Santos, Alberto BaêtaFerreira, EvaneStone, Luís Fernandoda Silva, Silvando CarlosRamos, Cristina Guimarães2002-10-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/6485Pesquisa Agropecuaria Brasileira; v.37, n.10, out. 2002; 1413-1420Pesquisa Agropecuária Brasileira; v.37, n.10, out. 2002; 1413-14201678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/6485/3542info:eu-repo/semantics/openAccess2014-07-22T17:52:48Zoai:ojs.seer.sct.embrapa.br:article/6485Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2014-07-22T17:52:48Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false |
