The work was carried out in Dourados MS, with the objective of evaluating yield and gross income in mono-cropping and inter-cropping system. Mono-croppings of 'Cultivada' roquette-R and 'Amarelo' chicory-A, in three rows (A3) and four (A4) rows and R3A4 and R4A3 intercropping systems were studied in randomized block design, with five replications. Harvests were done at 52 days after sowing and at 35 days after the first harvest. For roquette and chicory, respectively, plant heights (26.54 and 24.99 cm), number of leaves per plant (23.4 and 16.40), length (18.62 and 24.68 cm) and area of one leaf (66.73 and 177.0 cm²) were not influenced by number of rows, neither by intercropping system, but results were greater for the first harvest than the second. Length of chicory leaf was significantly influenced by intercropped system and number of rows interaction, which ranged from 22.74 (R4) up to 26.78 cm (R3A4). Yield of fresh (15.66 and 11.62 t ha-1) and dried (1.33 and 1.00 t ha-1) mass of roquette under four and three rows were significantly different, respectively. Fresh and dried matter of chicory treatments were, respectively, 12.55 and 0.85 t ha-1 for A3, 15.60 and 1.13 t ha-1 for A4, 17.44 and 1.26 t ha-1 under mono-cropping system and 10.72 and 0.72 t ha-1 under intercropping system. LER for the first and the second harvests were 1.87 and 1.76 for R3A4 and 1.56 and 1.58 for R4A3, respectively. R4A3 arrangement could have produced monetary increases of R$ 28,279.80 and R$ 20,065.60 for the second harvest, regarding to roquette and chicory. The best gross income for the second harvest was in R4A3 treatment, with corresponded to 87% of the best gross income of the first harvest for the same treatment, with a shorter 17-day vegetative cycle.
