The objective of this research was to evaluate combinations of cultivars of coriander and arugula in two croppings with cultivars of carrot in a strip-intercropping system. The study was conducted from November 2014 to March 2015. The experimental design was a randomized complete block in a 2 x 2 x 2 + 2 factorial scheme, with four replications. The treatments consisted of the combination of two cultivars of coriander (Verdão and Português) with two cultivars of carrot (Brasília and Esplanada) and two cultivars of arugula (Cultivada and Folha Larga) in a strip-intercropping system plus two additional treatments, where the first represents the cultivars in monocropping and the second the cultivation types (monocropping and intercropping). The characteristics evaluated in the coriander and arugula were green mass yield and shoot dry mass. The following were evaluated in carrot: shoot dry mass, dry mass of roots, total and commercial productivity, and classified productivity of roots. In the intercropping system, the agronomic indices of land equivalent ratio, productive efficiency index, and score of the canonical variable were evaluated. The economic efficiency indicators determined were gross and net income, rate of return, profit margin, monetary advantage, and modified monetary advantage. There was no significant interaction among the cultivars of coriander, carrot, and arugula for coriander and arugula green mass yields, and for total and commercial productivities of carrot roots. The best polyculture was of that involved in the cultivars ―Português,‖ ―Esplanada,‖ and ―Cultivada‖.
