Resumo: The objective of the present study was to analyze the relationship between rainfall variability and cassava yield in the municipality of Cruzeiro do Sul-Acre, taking into account the rainfall regime as an essential input for agriculture. Data on total monthly and annual rainfall observed in the city from 1993 to 2018 were used. the analyzed period. In 1995, it was verified that the registered values of rainfall are far from the average value. Regarding the years of cassava productivity, it is possible to verify that until the year 2012 there were no significant variations in the evaluated records. In the period 1993 to 2012, the highlight is the year 2010, whose productivity exceeded the value of 20 t.ha-1. It was found that from the year 2013 the highest productivity values for the cassava crop were recorded. In the interval between the years 2013 and 2018, the municipality recorded the highest productivity values during the analyzed period. The year 2015 stood out with a productivity that reached 32.3 t.ha-1. There was also an upward trend in crop productivity through growth in rainfall values. Through simple linear regression analysis, it was evidenced an increasing increase of 0.0043 t.ha-1 in cassava yield as a function of 1 mm of rain, in the city of Cruzeiro do Sul.

Se utilizaron datos de precipitaciones totales mensuales y anuales observadas en la ciudad desde 1993 hasta 2018. El período analizado. En 1995 se comprobó que los valores registrados de precipitación están lejos del valor medio. En cuanto a los años de productividad de la yuca, se puede verificar que hasta el año 2012 no hubo variaciones significativas en los registros evaluados. En el período (1993 a 2012), se destaca el año 2010, cuya productividad superó el valor de 20 t.ha-1. Se encontró que a partir del año 2013 se registraron los mayores valores de productividad para el cultivo de yuca. En el intervalo entre 2013 y 2018, el municipio registró los mayores valores de productividad durante el período analizado. El año 2015 se destacó con una productividad que alcanzó las 32,3 t.ha-1. También hubo una tendencia al alza en la productividad de los cultivos a través del aumento de los valores de precipitación. Mediante análisis de regresión lineal simple, se evidenció un aumento creciente de 0,0043 t.ha-1 en el rendimiento de yuca en función de 1 mm de lluvia, en la ciudad de Cruzeiro do Sul.O objetivo do presente estudo foi analisar a relação existente entre a variabilidade pluviométrica e a produtividade de mandioca no município de Cruzeiro do Sul-Acre, levando em consideração o regime pluviométrico como insumo essencial para a agricultura. Foram utilizados os dados de precipitação pluviométrica total mensal e anual, observados na cidade, no período de 1993 a 2018. No ano de 1993 tem-se o menor valor de produtividade, enquanto a precipitação pluviométrica registrada se aproxima do valor da precipitação média calculada para o período analisado. No ano de 1995, verificou-se que os valores registrados de precipitação pluviométrica se distanciam do valor médio. Em relação aos anos de produtividade de mandioca, é possível verificar que até o ano de 2012 não ocorreram variações significativas nos registros avaliados. No período 1993 a 20, o destaque é dado ao ano de 2010, cuja produtividade superou o valor de 20 t.ha-1. Verificou-se que a partir do ano de 2013 registrou-se os maiores valores de produtividade para a cultura da mandioca. Já no intervalo entre os anos de 2013 e 2018, o município registrou os mais altos valores de produtividade, durante o período analisado. O ano de 2015 destacou-se com uma produtividade que atingiu 32,3 t.ha-1. Verificou-se, também, tendência ascendente na produtividade da cultura mediante crescimento nos valores de precipitação pluviométrica. Por meio da análise de regressão linear simples, evidenciou um incremento crescente de 0,0043 t.ha-1 à produtividade de mandioca em função de 1 mm de chuva, na cidade de Cruzeiro do Sul.Research, Society and Development2022-06-19info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://rsdjournal.org/index.php/rsd/article/view/3077110.33448/rsd-v11i8.30771Research, Society and Development; Vol. 11 No. 8; e29411830771Research, Society and Development; Vol. 11 Núm. 8; e29411830771Research, Society and Development; v. 11 n. 8; e294118307712525-3409reponame:Research, Society and Developmentinstname:Universidade Federal de Itajubá (UNIFEI)instacron:UNIFEIporhttps://rsdjournal.org/index.php/rsd/article/view/30771/26526Copyright (c) 2022 Jefferson Rodrigues dos Santos Silva; Charniele Freitas da Costa; Rodrigo Otávio Peréa Serrano; Anderson Azevedo Mesquita; José Genivaldo do Vale Moreirahttps://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessSilva, Jefferson Rodrigues dos Santos Costa, Charniele Freitas da Serrano, Rodrigo Otávio Peréa Mesquita, Anderson Azevedo Moreira, José Genivaldo do Vale 2022-07-01T13:34:06Zoai:ojs.pkp.sfu.ca:article/30771Revistahttps://rsdjournal.org/index.php/rsd/indexPUBhttps://rsdjournal.org/index.php/rsd/oairsd.articles@gmail.com2525-34092525-3409opendoar:2024-01-17T09:47:24.790351Research, Society and Development - Universidade Federal de Itajubá (UNIFEI)false
