Conteúdo: | Eight sorghum genotypes were grown at Hyderabad, India, in sole crop and in association with cowpea in six environments which differed in soil, season and sowing date . There were genotype x environment (G X E) interactions for sorghum yield and related variables, but the interaction was generally much smaller than the main effects . For each variable, the logarithm of the intercrop : sole crop ratio was generally less sensitive to the environment, but there was a significant G X E interaction for the logarithm of land equivalent ratio, indicating that the precise pattern of G x E effects differed between cropping systems . There was little evidence of G x E effects on cowpea, indicating that the effects of a sorghum genotype on the associated legume will be relatively simple to assess . The total LER was above 1 in most cases, indicating that intercropping gives a yield advantage over a wide range of environments and sorghum genotypes .
