Our aim was to verify if intercropping systems of crisphead lettuce and radish were economically viable. The costs of production of the cultures were evaluated in monoculture and in intercropping. Some agrieconomic indicators were used to evaluate the efficiency of the systems such as the appropriate use of the land gross and net revenue, monetary advantage, corrected monetary advantage, rate of return and profit margin were used to evaluated the efficiency of intercropping systems. The association of the lettuce and radish allowed a better use of the production factors, with increase in the production per unit of area. The intercropping systems established in 0 (spacing between rows of 0.30 x 0.30 m) and to 14 (spacing between rows of 0.40 x 0.30 m) days after the transplant of crisphead lettuce presented the best agrieconomics indicators, with land equivalent ratios of 1.76 and 1.61, rates of return of 4.13 and 4.53, and profit margins of 75.77% and 77.94%, respectively.
