Resumo:  Gerbera cultivation in the northeastern region of Brazil is still incipient, but it can be an alternative to crop diversification. The use of irrigation strategies can mitigate competition for available water, especially during water crisis. The objective of this study was to evaluate the production and quality of the inflorescences of gerberas as a function of water applied in the São Francisco Submédio Valley. This work was conducted in Juazeiro-BA, in a randomized block design, with 2 × 4 subdivided plots. The main plots consisted of two gerbera hybrids (Essandre and DTCS), and the subplots were composed of four areas established at 60%, 80%, 100%, and 120% of the crop evapotranspiration (ET), in five replications. ET was determined by weighing lysimeter, in a 240-day cycle after acclimatization. The number, length, diameter, and longevity of the stems were quantified. Means were compared using Tukey’s test at 5% significance level, and regression analysis was performed on the subplot ET factor. The severe deficit made commercial production of cutting gerbera unfeasible. The DTCS hybrid showed higher production and quality of the flowers; however, there was a reduction in the length of the stem and the longevity of the inflorescence compared to Essandre, due to the differentiation of the ET areas. The 20% water deficit may be a positive approach to water management in the face of water scarcity, but it can result in a 13% loss of the commercial production, and a 12.4% reduction in the quality of the stems. The water-saving strategy for gerbera crop requires economic analysis.

El uso de estrategias de riego puede minimizar la competencia por el agua disponible, especialmente durante la crisis hídrica. El objetivo de este estudio realizado en Juazeiro-BA fue evaluar la producción y la calidad de las inflorescencias de gerbera respecto a la función de agua aplicada al Valle Submedio de San Francisco. Se utilizó un diseño en bloque aleatorizado, con parcelas subdivididas de 2x4. Las parcelas principales estaban compuestas por dos híbridos de gerbera (Essandre y DTCS), mientras que las subparcelas estaban integradas por cuatro áreas establecidas a 60 %, 80 %, 100 % y 120 % de evapotranspiración (ET) del cultivo, en cinco replicaciones. Se determinó la ET a través de un lisímetro de pesaje, en un ciclo de 240 días posterior a la aclimatación, y se cuantificó la cantidad, la longitud, el diámetro y la longevidad de los tallos. Las medias se compararon utilizando la prueba de Tukey en un nivel de significancia de 5%, a la vez que se llevó a cabo un análisis de la regresión en el factor ET de la subparcela. El grave déficit hizo inviable la producción comercial de la flor de corte de gerbera. Se observó una mayor producción y mejor calidad en las flores híbridas DTCS; sin embargo, en contraste con Essandre, tanto la longitud del tallo como la longevidad de la inflorescencia disminuyeron como resultado de la diferenciación entre las áreas de ET. El déficit hídrico del 20 % podría considerarse un enfoque positivo para la gestión del agua frente a la escasez hídrica, aunque podría generar una pérdida del 13 % de la producción comercial, además de una reducción del 12,4 % en la calidad de los tallos. La estrategia de ahorro de agua para el cultivo de gerbera exige un análisis económico. O cultivo de gérbera na região nordeste brasileira ainda é insipiente, mas pode apresentar-se como alternativa à diversificação de cultivos.  O uso de estratégias de irrigação pode atenuar eventos de concorrência pela água disponível, especialmente frente à crise hídrica.  Objetivou-se avaliar a produção e a qualidade das inflorescências de gérberas em função da água aplicada, no Submédio do Vale do São Francisco. O trabalho foi desenvolvido em Juazeiro-BA, no delineamento experimental em blocos casualizados, com parcelas subdividas 2x4, com dois híbridos de gérberas (Essandre e DTCS) e as subparcelas compostas por quatro lâminas (60; 80; 100; e 120% da evapotranspiração da cultura), em cinco repetições. A evapotranspiração foi determinada por lisimetria de pesagem, num ciclo de 240 dias após a aclimatização (DAA). A quantidade, comprimento, diâmetro e a longevidade das hastes foram quantificados. As médias foram comparadas pelo teste de Tukey a 5% de significância e para fator lâmina fez-se análise de regressão. O déficit severo inviabilizou a produção comercial de gérbera de corte. O híbrido DTCS apresentou maior produção e qualidade das flores, contudo, houve redução no comprimento da haste e na longevidade da inflorescência em relação à Essandre, em função da diferenciação das lâminas. O déficit hídrico de 20% pode ser uma abordagem de gerenciamento positivo da água face à escassez dos recursos hídricos, mas pode promover 13% de perdas de produção comercial e redução de 12,4% da qualidade das hastes, sendo necessária uma análise econômica dessa estratégia de economia de água para a cultura da gérbera.Research, Society and Development2020-07-20info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://rsdjournal.org/index.php/rsd/article/view/577010.33448/rsd-v9i8.5770Research, Society and Development; Vol. 9 No. 8; e609985770Research, Society and Development; Vol. 9 Núm. 8; e609985770Research, Society and Development; v. 9 n. 8; e6099857702525-3409reponame:Research, Society and Developmentinstname:Universidade Federal de Itajubá (UNIFEI)instacron:UNIFEIporhttps://rsdjournal.org/index.php/rsd/article/view/5770/5308Copyright (c) 2020 Ligia Borges Marinho, Damiana de Oliveira Silva, Joselita Cardoso de Souza, Tomaz da Silva Felisberto, Carlos Alberto Aragão, Magnus Dall Igna Deon, Larissa de Sá Gomes Lealhttp://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessSilva, Damiana de OliveiraMarinho, Ligia BorgesSouza, Joselita Cardoso deFelisberto, Tomaz da SilvaAragão, Carlos AlbertoDeon, Magnus Dall IgnaLeal, Larissa de Sá Gomes2020-08-20T18:00:17Zoai:ojs.pkp.sfu.ca:article/5770Revistahttps://rsdjournal.org/index.php/rsd/indexPUBhttps://rsdjournal.org/index.php/rsd/oairsd.articles@gmail.com2525-34092525-3409opendoar:2024-01-17T09:29:10.851695Research, Society and Development - Universidade Federal de Itajubá (UNIFEI)false
