Resumo: The objective of this study was to determine the crop evapotranspiration (ETc), crop coefficients (kc) and water-use efficiency (EUA) of the bell pepper crop in the no till system (PD) and conventional tillage system (PC), in the Fluminense Valley, Rio de Janeiro State, Brazil. The irrigation was managed and the evapotranspiration demand quantified by calculating the daily soil water balance using the TDR technique and data collected in an automatic meteorological station. It was verified that the accumulated ETc at 181 days after planting (DAT) was 363 and 335 mm for PD and PC, respectively. The kcs obtained were 0.32, 1.18 and 0.77 and 0.34, 1.05 and 0.86, for the PD and PC systems, respectively, in the initial (0-40 DAP), middle (81-120 DAP) and final (181 DAP) growth phases, respectively. The kc values for the bell pepper crop presented by FAO were similar to the values found for the PC, but are not recommended for PD. Considering the total depth applied (rain and irrigation), the average values of water use efficiency were 3.9 and 4.5 kg m-3 for PD and PC, respectively.

O manejo da irrigação e a quantificação da demanda evapotranspirométrica foram realizados mediante o cálculo diário do balanço de água no solo, utilizando-se a técnica da TDR e dados coletados em estação meteorológica automática. Verificou-se que a ETc acumulada aos 181 dias após transplantio (DAT) foi de 363 e de 335 mm, para PC e PD, respectivamente. Os kc’s encontrados foram de 0,32; 1,18 e 0,77 e de 0,34; 1,05 e 0,86, para os sistemas PC e PD, nas fases de crescimento inicial (0-40 DAT), média (81-120 DAT) e final (181 DAT), respectivamente. Os valores encontrados de kc para a cultura do pimentão para o sistema PC foram semelhantes aos valores preconizados pela FAO, sendo, no entanto, não-recomendados para PD. Considerando-se a lâmina total aplicada (chuva e irrigação), os valores médios de EUA foram de 3,9 e 4,5 kg m-3 para PC e PD, respectivamente.Universidade Estadual de Maringá2011-02-16info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttp://www.periodicos.uem.br/ojs/index.php/ActaSciAgron/article/view/552710.4025/actasciagron.v33i1.5527Acta Scientiarum.
