Resumo: | The experiment was conducted at the Centro Técnico de Irrigação da Universidade Estadual de Maringá, in Maringá, PR, Brazil, in order to study the effect of irrigation and nitrogen fertilization on orange (Citrus sinensis Osbeck vr. Pêra) yield. The experimental design was entirely randomized with seven rates of irrigation (W0 = 0; W1 = 1.440; W2 = 2.880; W3 = 4.320; W4 = 5.760; W5 = 7.200 and W6 = 8.640l water/tree) and five rates of nitrogen (N0 = 0; N1 = 107,5; N2 = 215; N3 = 322,5; N4 = 430 and N5 = 537.5g N/tree). Irrigation was performed through a microsprinkler and controlled according to the evapotranspiration of the crop, estimated by a “class A” pan. Water was applied whenever the evapotranspiration reached 7,3mm. For the nitrogen fertilization, diluted urea was divided into 43 applications at a weekly rate. The production of boxes of fruits per tree presented quadratic relationship in function of the application of nitrogen and water, reaching the maximum of 3,2 boxes (40,8kg) per tree with the application of 5,095.6l of water and 345.9g of N per tree. |

Pêra), conduziu-se um experimento no Centro Técnico de Irrigação da Universidade Estadual de Maringá, Maringá, PR. O delineamento experimental foi inteiramente casualizado, com sete níveis de irrigação complementar (W0 = 0; W1 = 1.440; W2 = 2.880; W3 = 4.320; W4 = 5.760; W5 = 7.200 e W6 = 8.640l de água/árvore) e cinco níveis de nitrogênio (N0 = 0; N1 = 107,5; N2 = 215; N3 = 322,5; N4 = 430 e N5 = 537.5g de N/árvore). A irrigação foi realizada por microaspersão e controlada em função da evapotranspiração da cultura (Etc), estimada pelo tanque “Classe A”. Aplicou-se água sempre que Etc acumulada entre irrigações atingiu 7,3mm. Para adubação nitrogenada, usou-se uréia diluída em água, parcelada em 43 aplicações, com freqüência semanal. A produção de caixas de frutos por árvore apresentou relação quadrática em função da aplicação de nitrogênio e de água, atingindo o máximo de 3,2 caixas (40,8kg) por árvore, com a aplicação de 5095,6l de água e 345,9g de N por árvore.Universidade Estadual de Maringá2008-07-14info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttp://www.periodicos.uem.br/ojs/index.php/ActaSciAgron/article/view/428110.4025/actasciagron.v21i0.4281Acta Scientiarum.
