In order to examine plant populations and spatial arrangements of maize and beans intercropped, and experiment was carreid out at Filadelfia, Brazil, located at 10o45' S and 40o07' W at 550 m altitude. The average annual rainfall of the area is 811 mm. The statistical design was a randomized complete block with a split-plot arrangement, with four replications. Four population levels of maize (25.000, 50.000, 75.000, and 100.000 plants/ha) and beans (150.000, 200.000, 250.000, and 300.000 plants/ha) formed the main plots. The subplots were composed of five spatial arrangements (sole maize; 1M:2B; 1M:3B; 1M:4B; and sole beans). It was concluded that the best spatial arrangement was 1:3, comprising 12.500 plants/ha of maize and 150.000 plants/ha of beans.  acorn  aintercropping  aFeijão  aMilho  aPhaseolus Vulgaris  aZea Mays  aBean  aConsorciacao1 aLOPES, L.
