The objetive of this experiment was to evaluate the intercropping of soybean [Glycine max. (L.) Merrill] cultivar Doko and corn (Zea mays L..) cultivar BR 201 under different planting systems. The experiment was conducted at the Universidade Federal de Lavras experimental area in a Latossolo roxo distrofic with clay texture during the 1992/1993 agronomic year. The experimental design was a completely randomized block (3 x 3 + 4) with three repetitions; the factorial scheme was comprised by three intercropping systems (soybean in the corn row: soybean between corn row and soybean on both at the same time), three corn planting designs (one plant every 25cm: two plants every 50cm; and four plants every 100cm) and four additional treatments (three corn planting designs in monoculture plus soybean). Corn yield, plant height and final stand were not significantly influenced by intercropping soybean. In relation to the monoculture the intercropping soybean has presented an increase in lodging and a reduction of grain yield. Among the soybean intercropping systems. the soybean planted in and between corn rows was the one which has proportioned a higher grain yield. The efficiency of intercropping system over monoculture was observed with 1.40 average of land equivalent ratio (LER).
