Conteúdo: | A field study was conducted for two years (1991 and 1992) near Ames, Iowa, U.S.A., with the objective to identify the combination of soybean planting dates (pre-heading=PD1, heading=PD2 and post-heading=PD3 stage of wheat) and spatial arrangementes (SA) to maximize soybean grain yield. The SA for wheat (W) and soybean (S) rows were: 1W:1S, 2W:1S, 2W:2S, 3W:2S and 4W:3S. Planting dates (PD) of soybean did not affect wheat yield. No significant differences in yield between years were observed for soybean. The SA most productive for wheat were 1W:1S and 2W:1S and for soybean were 2W:2S and 4W:3S. The PD1 and PD2 were the most productive planting dates. Land equivalent ratio (LER) was higher in 1991 (1.70) than in 1992 (1.24), but no significant differences were found among SA and PD in combined years.
