Resumo: | The objective of this study was to evaluate the agro-economic efficiency of the intercropping of carrot with cowpea-vegetable under different spatial arrangements and population densities in the semi-arid conditions of the Brazilian Northeast. The study was conducted at the "Rafael Fernandes" Experimental Farm of the Universidade Federal Rural do Semi-Árido (UFERSA) during the period July 2013 to February 2014. The experimental design was of randomized complete blocks with four replications and treatments arranged in a 3 × 4 factorial scheme, where the first factor consisted of spatial arrangements (2:2; 3:3 and 4:4) and the second factor by population densities of cowpea-vegetables (100, 80, 60 and 40% of the recommended population in sole crop [RPSC]). All treatments were fertilized with roostertree (Calotropis procera [Ait.] R.Br.), which is a spontaneous species of the Caatinga biome. The indices of agronomic efficiency of the intercropping systems assessed were: land equivalent ratio, productive efficiency index and score of the canonical variable. The following economic indicators were also evaluated: gross income, net income, rate of return and profit margin. The agro-economic efficiency of the intercropping system of carrot with cowpea-vegetable was influenced by the spatial arrangements, with the 2:2 arrangements standing out from the others. The greatest agro-economic efficiency of the intercropping of carrot with cowpea-vegetable was obtained in the population density of 100% of the RPSC when the value of the productive efficiency index was 0.75. |

O estudo foi realizado na Fazenda Experimental “Rafael Fernandes” da Universidade Federal Rural do Semi-Árido (UFERSA) no período de julho 2013 a fevereiro de 2014. O delineamento experimental adotado foi de blocos completos casualizados com quatro repetições, com os tratamentos arranjados em um esquema fatorial 3 x 4, sendo o primeiro fator constituído pelos arranjos espaciais (2:2; 3:3 e 4:4) e o segundo fator pelas densidades populacionais do caupi-hortaliça (100%, 80%, 60% e 40% da população recomendada no cultivo solteiro – PRCS). Todos os tratamentos foram fertilizados com flor-de-seda (Calotropis procera (Ait.) R.Br.), que é uma espécie espontânea do bioma Caatinga. Os índices de eficiência agronômica dos sistemas consorciados avaliados foram: índice de uso eficiente da terra, índice de eficiência produtiva e escore da variável canônica. Foram também avaliados os seguintes indicadores econômicos: renda bruta, renda líquida, taxa de retorno e índice de lucratividade. A eficiência agroeconômica do sistema consorciado de cenoura com caupi-hortaliça foi influenciada pelos arranjos espaciais, com o arranjo 2:2 sobressaindo-se dos demais. A maior eficiência agroeconômica do consórcio de cenoura com caupi-vegetal foi obtida na densidade populacional de 100% da PRCS quando o valor do índice de eficiência produtiva foi de 0,75.Universidade Federal Rural do Semi-Árido2017-06-14info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufersa.edu.br/caatinga/article/view/594010.1590/1983-21252017v30n404rcREVISTA CAATINGA; Vol. 30 No. 4 (2017); 847-854Revista Caatinga; v. 30 n. 4 (2017); 847-8541983-21250100-316Xreponame:Revista Caatingainstname:Universidade Federal Rural do Semi-Árido (UFERSA)instacron:UFERSAenghttps://periodicos.ufersa.edu.br/caatinga/article/view/5940/pdfRibeiro, Giorgio MendesBezerra Neto, FranciscoLima, Jailma Suerda Silva deSilva, Maiele Leandro daBarros Júnior, Aurélio PaesSantos, Elizangela Cabral dosinfo:eu-repo/semantics/openAccess2023-07-20T11:28:12Zoai:ojs.periodicos.ufersa.edu.br:article/5940Revistahttps://periodicos.ufersa.edu.br/index.php/caatinga/indexPUBhttps://periodicos.ufersa.edu.br/index.php/caatinga/oaipatricio@ufersa.edu.br|| caatinga@ufersa.edu.br1983-21250100-316Xopendoar:2024-04-29T09:46:25.413245Revista Caatinga - Universidade Federal Rural do Semi-Árido (UFERSA)true |
