Resumo: This work was conducted to study the effect of five water regimes on the onion production and bulb mean weight of variety 'Amarela Chata das Canárias'. The treatments consisted in irrigating when soil water was depleted to -0.1, -05, -1, -2 and -4 bars levels of matric potential. At harvest, production and bulb mean weight were obtained. For production, significative difference was found between the treatments at 0.05 level. The productions of treatments -0.5, -1, -2 and -4 bays did not differ statistically. The greatest production was obtained for irrigation treatment -0,1 bar, which was 81.7% higher than the production mean of the other treatment. The bulb mean weight decreased with decreasing soil matric potential (increasing suction). The mean weights were 130, 72, 63, 58 and 52.5 grams for the treatments watered at -0.1, -0,5. -1, -2 and -4 bars. The commercial productions with bulb mean weight in the range of 50- 150 grams were 45, 70, 65, 60 and 50% of total production, respectively, for the same water regimes.

Os tratamentos consistiram em se usar a irrigação quando o potencial matricial do solo atingisse -0,1; -0,5; -1; 2 e -4 bares. Por ocasião da colheita de terminaram-se a produção e o peso médio dos bulbos. Para a produção de bulbos, verificou-se diferença significativa ao nível de 5% de probabilidade entre os tratamentos de irrigação. Nos níveis de irrigação de -0,5; -1; -2 e -4 bares, as produções não diferiram estatisticamente. A maior produção foi obtida com o controle da irrigação a -0,1 bar, sendo 81,7% maior que a média dos outros tratamentos. O peso médio dos bulbos de cebola diminuiu com a diminuição do potencial matricial no solo (maior sucção). Os valores médios foram 130, 72, 63, 58 e 52,5 gramas para os tratamentos manejados a -0,1; -0,5; -1; -2 e -4 bares de potencial matricial no solo. Entretanto, as produções comerciais com peso de bulbos na faixa 50 - 150 gramas foram 45, 70, 65, 60 e 50% da produção total, respectivamente, para os mesmos tratamentos.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraAbreu, Tânia A. dos SantosMillar, Augustin A.Choudhury, Eliane NogueiraChoudhury, Mohammad M.2014-04-15info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/16531Pesquisa Agropecuaria Brasileira; v.15, n.2, fev. 1980; 233-236Pesquisa Agropecuária Brasileira; v.15, n.2, fev. 1980; 233-2361678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/16531/10806info:eu-repo/semantics/openAccess2014-04-15T19:32:16Zoai:ojs.seer.sct.embrapa.br:article/16531Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2014-04-15T19:32:16Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
