Results from 1985 determined sorghum x soybean as the most appropriate intercropping combination for the environment of the Marana Agricultural Center. In the 1986 cropping season, three sorghum genotypes (Pioneerr 8493, Funks G-522DR, and California IO80H40) were combined with three soybean genotypes (Asgrow A6324, Asgrow A6520, and Rillito), to identify the best genotype combination for intercropping. Both 1985 and 1986 experiments were carried out in a randomized complete block design with four replications. Pearl millet was the cereal with the greatest decrease in yield when intercropped, indicating that this cereal was not a good competitor with legumes. Sorghum was the best cereal competitor with the legumes and soybean was the best legume competitor with the cereals. Among the three sorghum genotypes studied in 1986, only Pioneer 8493 showed higher yield in monocrop whereas the other two genotypes yielded higher in intercropping, indicating some benefit from this system.On the average,(...).  aintercropping  aCereal  aFeijão de Corda  aGlycine Max  aLegume  aMilheto  aMilho  aPennisetum Americanum  aPhaseolus Vulgaris  aSoja  aSorghum Bicolor  aSorgo  aVigna Unguiculata  aZea Mays  aConsorcio  aCowpea  aMaize  aMillet  aSorghum  aSoybean
