Produção e renda bruta de rúcula ( Eruca sativa Mill.)... 775Ciênc. agrotec., Lavras, v. 29, n. 4, p. 775-785, jul./ago., 2005 , para a primeira e segunda colheita, foi de 1,87 e 1,76 para R 3 A 4 e 1,56 e 1,58 para R 4 A 3, respectivamente. O arranjo R 4 A 3 poderia ter gerado incrementos monetários por hectare de R$ 28.279,80 e de R$ 20.065,95 na primeira colheita e R$ 18.703,35 e de R$ 17.283,60 na segunda colheita, em relação ao almeirão e a rúcula solteira. A melhor renda bruta na segunda colheita foi no tratamento R 4 A 3 , correspondendo a 84,27% da melhor renda bruta obtida na primeira colheita, no mesmo tratamento, em ciclo vegetativo 17 dias menor.

ABSTRACTThe 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 (A 3 ) and four (A 4 ) rows and R 3 A 4 and R 4 A 3 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 cm 2 ) 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 (R 4 ) up to 26.78 cm (R 3 A 4 ). Yield of fresh (15.66 and 11.62 t ha -1 ) and dried (1.33 and 1.00 t ha -1
