Resumo: | Spatial arrangement and population density of component cultures, when well structured, may contribute to increased crop yields relative to monocultures. Thus, the objective of this work was to evaluate the productive performance of carrot and cowpea in an intercropping system under different spatial arrangements and population densities. This research was conducted on the “Rafael Fernandes” experimental farm of the Universidade Federal Rural do Semi-Árido (UFERSA), Mossoró, RN, Brazil. The experimental design was a randomized complete block with four replicates, where the treatments were arranged in a 3 × 4 factorial scheme, in which the first factor was three spatial arrangements (2:2, 3:3, and 4:4) and the second factor was four different population densities of cowpea (100%, 80%, 60%, and 40% of the recommended population in the single crop [RPSC]). Rooster tree Calotropis procera (Ait.) R.Br., a spontaneous species of the ‘Caatinga’ biome, was used as fertilizer. The characteristics evaluated in carrot were as follows: total and commercial productivity of roots and classified root production. The following characteristics were evaluated for cowpea: number of pods per square meter, length and yield of green pods, number of grains per pod, 100-grain weight, and yield of green grains. The modified monetary advantage was used to evaluate the feasibility of the intercropped systems. Spatial arrangements between the component cultures did not influence the agro-economic performance of the carrot-cowpea intercropping system. The highest agro-economic performance of the carrot-cowpea intercropping was obtained in the population of cowpea, which was 42% of the RPSC. |

Assim, o objetivo deste trabalho foi avaliar o desempenho produtivo da cenoura e do feijão-caupi em sistema consorciado sob diferentes arranjos espaciais e densidades populacionais. Essa pessquisa foi conduzida na fazenda experimental "Rafael Fernandes" da Universidade Federal Rural do Semi-Árido (UFERSA), Mossoró, RN, Brasil. O delineamento experimental foi de blocos completos casualizados com quatro repetições, em esquema fatorial 3 x 4 em que o primeiro fator foi três arranjos espaciais (2: 2, 3:3 e 4:4) e o segundo fator quatro densidades populacionais de feijão-caupi (100, 80, 60 e 40% da população recomendada no cultivo solteiro - PRCS). O experimento foi adubado com flor-de-seda (Calotropis procera (Ait.) R.Br.), uma espécie espontânea do bioma Caatinga. As características avaliadas na cenoura foram: produtividade total e comercial de raízes e produtividade classificada de raízes. Para o feijão-caupi foi avaliado as seguintes características: número de vagens por metro quadrado, comprimento e produtividade de vagens verdes, número de grãos por vagem, peso de 100 grãos e produtividade de grãos verdes. A vantagem monetária corrigida foi utilizada para avaliar a viabilidade dos sistemas consorciados. Não se observou influencia dos arranjos espaciais entre as culturas componentes no desempenho agroeconômico do consórcio de cenoura x feijão-caupi. A mais alta performance agroeconômica do consórcio cenoura x feijão-caupi foi obtida na densidade populacional de caupi de 42% da PRCS.Universidade Federal Rural do Semi-Árido2017-12-11info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufersa.edu.br/caatinga/article/view/595510.1590/1983-21252018v31n103rcREVISTA CAATINGA; Vol. 31 No. 1 (2018); 19-27Revista Caatinga; v. 31 n. 1 (2018); 19-271983-21250100-316Xreponame:Revista Caatingainstname:Universidade Federal Rural do Semi-Árido (UFERSA)instacron:UFERSAenghttps://periodicos.ufersa.edu.br/caatinga/article/view/5955/pdfRibeiro, Giorgio MendesNeto, Francisco BezerraLima, Jailma Suerda Silva deSilva, Maiele Leandro daBarros Júnior, Aurélio PaesSantos, Elizangela Cabral dosinfo:eu-repo/semantics/openAccess2023-07-20T11:46:09Zoai:ojs.periodicos.ufersa.edu.br:article/5955Revistahttps://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:2024-04-29T09:46:25.690832Revista Caatinga - Universidade Federal Rural do Semi-Árido (UFERSA)true |
