Resumo: | The Zona da Mata Pernambucana stands out for offering rich soils for planting sugar cane, due to its great social, economic and environmental importance for the country. The high representativeness of sugarcane in the value of production compared to other products from temporary crops, corroborate the economic importance in the micro-region. Using data from the website of the Brazilian Agricultural Research Corporation (Embrapa), this study aims to analyze whether there is a significant difference in terms of production of sugarcane, in tons/ha, between the periods 1990-2003 and 2004- 2017, in the micro-region of Vitória de Santo Antão/PE, Brazil. For the analysis, it was necessary to evaluate the two periods independently. Thus, the statistical software IBM SPSS STATISTICS 23 was used in order to assess the normality of the data through the Shapiro-Wilk test, which indicated that the data do not follow normality at the 0.05 significance level. Consequently, the Mann-Whitney test was applied, as it is a non-parametric test and considers the independence of the years. The results obtained by the test, with an exact significance of 0.94, indicated that there is no significant difference between the periods, that is, the microregion maintains the production of sugarcane each year, which makes the permanence of the cultivation of sugar cane for it. |

La alta representatividad de la caña de azúcar en el valor de la producción frente a otros productos de cultivos temporales, corroboran la importancia económica en la microrregión. Utilizando datos del sitio web de la Corporación Brasileña de Investigación Agropecuaria (Embrapa), este estudio tiene como objetivo analizar si existe una diferencia significativa en términos de producción de caña de azúcar, en toneladas/ha, entre los períodos 1990-2003 y 2004- 2017, en la microrregión de Vitória de Santo Antão/PE, Brasil. Para el análisis fue necesario evaluar los dos períodos de forma independiente. Así, se utilizó el software estadístico IBM SPSS STATISTICS 23 para evaluar la normalidad de los datos mediante la prueba de Shapiro-Wilk, que indicó que los datos no siguen la normalidad al nivel de significancia 0.05. En consecuencia, se aplicó la prueba de Mann-Whitney, por ser una prueba no paramétrica y considera la independencia de los años. Los resultados obtenidos por la prueba, con una significación exacta de 0.94, indicaron que no existe diferencia significativa entre los períodos, es decir, la microrregión mantiene a producción de caña de azúcar a cada año, lo que hace que la permanencia del cultivo de caña de azúcar para ello.A Zona da Mata Pernambucana se destaca por oferecer solos ricos para a plantação da cana-de-açúcar, devido sua grande importância social, econômica e ambiental para o país. A alta representatividade da cana-de-açúcar no valor da produção comparada aos demais produtos das lavouras temporárias, corroboram para a importância econômica na microrregião. Dispondo de dados provenientes do site da Empresa Brasileira de Pesquisa Agropecuária (Embrapa), a presente pesquisa teve como objetivo, analisar se houve diferença significativa quanto à produção de cana-de-açúcar, em toneladas/ha, entre os períodos de 1990-2003 e 2004-2017, na microrregião de Vitória de Santo Antão/PE, Brasil. Para a análise, foi necessário que se avaliasse, de forma independente, os dois períodos. Assim, utilizou-se o software estatístico IBM SPSS STATISTICS 23, a fim de avaliar a normalidade dos dados através do teste de Shapiro-Wilk, o qual indicou que os dados não seguem normalidade ao nível de significância de 0,05. Em conseguinte, foi aplicado o teste de Mann-Whitney, por ser um teste não paramétrico e considerar a independência dos anos. Os resultados obtidos pelo teste, com significância exata de 0,94 indicaram que não há uma diferença significativa entre os períodos, ou seja, a microrregião mantém uma produção média de 326,54 toneladas de cana-de-açúcar a cada período, o que torna viável a permanência do cultivo de cana-de-açúcar para a mesma.Research, Society and Development2020-11-13info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://rsdjournal.org/index.php/rsd/article/view/985710.33448/rsd-v9i11.9857Research, Society and Development; Vol. 9 No. 11; e2669119857Research, Society and Development; Vol. 9 Núm. 11; e2669119857Research, Society and Development; v. 9 n. 11; e26691198572525-3409reponame:Research, Society and Developmentinstname:Universidade Federal de Itajubá (UNIFEI)instacron:UNIFEIporhttps://rsdjournal.org/index.php/rsd/article/view/9857/8947Copyright (c) 2020 Maria Marciele de Lima Silva; Natália Moraes Cordeiro; Gabriela Isabel Limoeiro Alves Nascimento; Lucas Silva do Amaral; Elielma Santana de Jesus; João Silva Rocha; Henrique Correia Torres dos Santos; José Eduardo Silva; Wagner Ranyere Leão da Silva; Taís Cristina de Melo Silva; Jonnathan Felipe Araújo Guimarães; Romário Professor da Silva; Jonnathan Felipe Araújo Guimarães; José Antonio Aleixo da Silva; Guilherme Rocha Moreira ; Moacyr Cunha Filho; Antonio Samuel Alves da Silva https://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessSilva, Maria Marciele de Lima Cordeiro, Natália Moraes Nascimento, Gabriela Isabel Limoeiro Alves Amaral, Lucas Silva doJesus, Elielma Santana de Rocha, João Silva Santos, Henrique Correia TorresSilva, José Eduardo Silva, Wagner Ranyere Leão daSilva, Taís Cristina de Melo Silva, Romário Professor da Guimarães, Jonnathan Felipe Araújo Silva, José Antônio Aleixo da Moreira , Guilherme Rocha Cunha Filho, Moacyr Silva , Antonio Samuel Alves da 2020-12-10T23:37:57Zoai:ojs.pkp.sfu.ca:article/9857Revistahttps://rsdjournal.org/index.php/rsd/indexPUBhttps://rsdjournal.org/index.php/rsd/oairsd.articles@gmail.com2525-34092525-3409opendoar:2024-01-17T09:32:02.511938Research, Society and Development - Universidade Federal de Itajubá (UNIFEI)false |
