Abstract ABSTRACT The integration of research emphasizing sustainable development, employment, income generation and food security has been highlighted in the media. The objective of this research was to evaluate the agro-economic responsiveness of radish associations with cowpea in the presence of different amounts of roostertree, spatial arrangements and agricultural crops. The experimental design was a randomized block design with four replications, with treatments arranged in a 4 x 3 factorial scheme, where the first factor consisted of four amounts of C. procera incorporated in the soil (20, 35, 50 and 65 t ha-1 on a dry basis) and the second factor of three spatial arrangements (2:2, 3:3, and 4:4) in two cropping seasons. Radish samples were evaluated for plant height, dry mass of shoots, total and commercial productivity of roots, productivity of scrap roots, and dry mass of roots, while in cowpea, vegetation was assessed for length of green pods, number of pods per square meter, productivity and dry mass of green pods, number of green grains per pod, weight of 100 green grains, and yield and dry mass of green grains. The economic indicators of monetary advantage and modified monetary advantage were used in the evaluation of efficiency. A greater agro-economic responsiveness of the intercropping of radish and cowpea crops was obtained with the incorporation of 56.44 t ha-1 of C. procera. The spatial arrangements of 3:3 and 4:4 had better agronomic and economic responsiveness. The association between radish and cowpea is feasible when the crops are fertilized with C. procera. RESUMO A integração de pesquisas enfatizando o desenvolvimento sustentável, o emprego, a geração de renda e a segurança alimentar vêm sendo destaque nos meios de divulgação. Assim, o objetivo desta pesquisa foi avaliar a responsividade agroeconômica de associações de rabanete com caupi em diferentes quantidades de C. procera, arranjos espaciais e safras de cultivo. O delineamento experimental foi o de blocos casualizados com quatro repetições, em esquema fatorial 4 x 3, onde o primeiro fator consistiu de quatro quantidades de C. procera incorporadas ao solo (20; 35; 50 e 65 t ha-1 em base seca) e o segundo de três arranjos espaciais (2:2; 3:3 e 4:4) em duas safras de cultivo. Amostras de rabanete foram avaliadas quanto à altura de plantas, massa seca da parte aérea, produtividade total e comercial de raízes, produtividade de raízes refugo e massa seca de raízes, enquanto que no caupi, as amostras foram avaliadas quanto ao comprimento de vagens verdes, número de vagens por m2, produtividade e massa seca de vagens verdes, número de grãos verdes por vagem, peso de 100 grãos verdes, produtividade e massa seca de grãos verdes. Os indicadores econômicos vantagem monetária e monetária corrigida foram utilizados na avaliação da eficiência do consórcio. Uma maior responsividade agroeconômica do consórcio de rabanete e caupi foi obtida com a incorporação de 56,44 t ha-1 de C. procera. Os arranjos espaciais 3:3 e 4:4 tiveram melhor responsividade em termos agronômico e econômico. A associação entre o rabanete e o caupi é viável quando as culturas são adubadas com C. procera.
