Abstract

The objective of this paper was to verify yield and gross income of lettuce and radish in monocrop and intercrop systems. Crespa Grand Rapids Nacional lettuce and Crimson Vip radish varieties were studied in monocrop system with three and four rows, as well as the R4A3 and R3A4 intercroppings. Radish cultivated under four rows of plants in plot had significant increase of 1.16 t ha^-1 of fresh mass in plants with commercial root in relation to those cultivated under three rows. In monocrop system, the highest values (16.36 cm height, 25.04 cm of diameter and 137,780 plants ha^-1) were obtained from four rows and with intercrop, the highest values of height (13.84 cm) and diameter (21.86 cm) were obtained from four rows, and the highest number of commercial plants (133,220 plants ha^-1) was obtained from three rows. Land Equivalent Ratio (LER) for R4A3 intercropping was 1.69 and for R3A4, it was 2.05. Considering gross income, R3A4 intercropping is recommended because it induced monetary increases of R$ 24,748.00; R$ 1,224.00 and R$ 39,686.00 in relation to R4A3 intercropping and to monocrop system with four rows of lettuce and radish, respectively.
