Resumo: The objective of this study was to establish a water management strategy for processing tomato vegetative growth stage, under "cerrado" conditions in the Central region of Brazil. Six irrigation interval treatments ranging from 0.5 to 16 days were evaluated. Plant final stand, biomass production, and fruit yield showed a quadratic response to irrigation interval, reaching a maximum for irrigation frequency of 2, 1, and 2 days, respectively. Average fruit mass and number of fruit per plant were not influenced by the irrigation intervals, suggesting that observed yield differences resulted from treatments effect on plant stand. Effective rooting depth increased linearly with irrigation frequency. Plants irrigated at 8 and 16 days intervals showed a rooting system about 10 cm deeper than those irrigated twice a day. Titratable acidity, total soluble solids content, and rotten fruit rate were not affected by irrigation frequency. For best tomato crop performance, irrigations during vegetative stage should be given at a 2-day frequency, which corresponds to a soil water tension of 17 kPa.

Foram avaliados seis turnos de rega entre 0,5 e 16 dias. O estande final e a produtividade de frutos, maximizados em regas a cada 2 dias, apresentaram resposta quadrática com a freqüência de irrigação, enquanto a produção de biomassa foi maximizada em regas diárias. A massa média de fruto e o número de frutos por planta não foram influenciados pelos tratamentos; isto indica que as diferenças de produção foram causadas, principalmente, pela variação do estande final. A profundidade efetiva de raízes apresentou resposta linear positiva com o turno de rega. As plantas irrigadas a cada 8 e 16 dias apresentaram um sistema radicular cerca de 10 cm mais profundo do que aquelas irrigadas duas vezes por dia. O teor de sólidos solúveis totais, a acidez titulável e a taxa de fruto podre não foram influenciados pelos turnos de rega. Observou-se que para melhor desempenho do tomateiro, durante o estádio vegetativo as irrigações devem ser realizadas a cada 2 dias, ou seja, quando a tensão de água no solo atingir cerca de 17 kPa.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraMarouelli, Waldir AparecidoSilva, Washington Luiz de Carvalho e2005-07-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/7009Pesquisa Agropecuaria Brasileira; v.40, n.7, jul. 2005; 661-666Pesquisa Agropecuária Brasileira; v.40, n.7, jul. 2005; 661-6661678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/7009/4057info:eu-repo/semantics/openAccess2014-09-22T17:03:48Zoai:ojs.seer.sct.embrapa.br:article/7009Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2014-09-22T17:03:48Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
