Resumo: | The appropriate use of nitrogen fertilization and higher population densities increase the pineapple yield and can improve economic returns. This study aimed to evaluate the economic return and postharvest characteristics of irrigated Vitória pineapple under different nitrogen (N) sources and doses, as well as the increase in population density. A randomized blocks design with three replications was installed in a 2 x 5 x 4 factorial scheme, corresponding to two N sources (urea and cattle manure), five N doses (0 g plant-1, 5 g plant-1, 10 g plant-1, 15 g plant-1 and 20 g plant-1) and four densities (51,282 plants ha-1, 76,923 plants ha-1, 90,909 plants ha-1 and 126,984 plants ha-1). The N sources did not affect the pH, total titratable acidity and total soluble solids/total titratable acidity ratio (TSS/TTA). However the TSS content was higher in plants fertilized with cattle manure. The plants density did not affect the quality of postharvest fruit. The increase of N doses supplied by urea and cattle manure influenced only the total titratable acidity of the fruits. The combination of 20 g plant-1 of N-manure and a population of 126,984 plants ha-1 resulted in the maximum partial net income of R$ 132,096.48, however, the dose of 19.75 g plant-1 of N-urea, in the population of 119,686.00 plants ha-1, reached a partial net income of R$ 154,997.15. |

Objetivou-se avaliar a rentabilidade econômica e as características de qualidade pós-colheita do abacaxizeiro Vitória irrigado, sob diferentes fontes e doses de nitrogênio (N), bem como o aumento da densidade populacional. Utilizou-se o delineamento em blocos casualizados, com três repetições, em esquema fatorial 2 x 5 x 4, correspondendo a duas fontes de N (ureia e esterco bovino), cinco doses de N (0 g planta-1, 5 g planta-1, 10 g planta-1, 15 g planta-1 e 20 g planta-1) e quatro densidades (51.282 plantas ha-1, 76.923 plantas ha-1, 90.909 plantas ha-1 e 126.984 plantas ha-1). As fontes de N não interferiram no pH, acidez total titulável e relação sólidos solúveis totais/acidez total titulável (SST/ATT). Entretanto, o teor de SST foi superior nas plantas adubadas com esterco bovino. A densidade de plantas não interferiu na qualidade de pós-colheita dos frutos. O aumento das doses de N fornecidas via ureia e esterco bovino influenciou somente a acidez total titulável dos frutos. Com a adição de 20 g planta-1 de N-esterco e população de 126.984 plantas ha-1 obteve-se o máximo rendimento líquido parcial de R$ 132.096,48. No entanto, a dose de 19,75 g planta-1 de N-ureia, na população de 119.686,00 plantas ha-1, resultou em rendimento líquido parcial de R$ 154.997,15.Escola de Agronomia - Universidade Federal de Goiás2015-02-27info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionPesquisa Experimentalapplication/pdfhttps://revistas.ufg.br/pat/article/view/27998Pesquisa Agropecuária Tropical [Agricultural Research in the Tropics]; v. 45, n. 1, Jan./Mar. 2015; 39-45Pesquisa Agropecuária Tropical (Agricultural Research in the Tropics); v. 45, n. 1, jan./mar. 2015; 39-45Pesquisa Agropecuária Tropical; v. 45, n. 1, jan./mar. 2015; 39-451983-4063reponame:Pesquisa Agropecuária Tropical (Online)instname:Universidade Federal de Goiás (UFG)instacron:UFGporhttps://revistas.ufg.br/pat/article/view/27998/18030Copyright (c) 2020 Pesquisa Agropecuária Tropical (Agricultural Research in the Tropics)info:eu-repo/semantics/openAccessSilva, Deivisson Ferreira daPegoraro, Rodinei FaccoMedeiros, Ananias CostaLopes, Paulo Augusto PereiraCardoso, Maurício MendesMaia, Victor Martins2020-07-13T15:57:14Zoai:ojs.revistas.ufg.br:article/27998Revistahttps://revistas.ufg.br/patPUBhttps://revistas.ufg.br/pat/oaiaseleguini.pat@gmail.com||mgoes@agro.ufg.br1983-40631517-6398opendoar:2024-05-21T19:56:06.031481Pesquisa Agropecuária Tropical (Online) - Universidade Federal de Goiás (UFG)true |
