Four groups of sorghum genotypes were compared, both as sole crops and in intercrops with soybeans, in a replicated experiment. S1 and S2 genotypes were superior both as intercrops and as sole crops, and intercropping was better than sole cropping for all genotypes. The economic yield was 28 per cent higher through intercropping. When the S1 and S2 genotypes were intercropped, there was increased yield per plant. This increase was attributed to more grains per head. Their growth was rapid and vigorous and did not allow soybeans'to become the dominant crop in the mixture. The best intercrop combinations of sorghum and the variety of soybeans used was found to consist of those involving low tillering short stature sorghum types with rapid and vigorous growth at the seedling stage. Intercropping caused yield reductions of both sorghum and soybeans in the mixture, with soybeans being more adversely affected. The yields of slow growing sorghum genotypes were also greatly reduced. Sorghum plant height and seed size were reduced in the mixture indicating that competition for nutrients, moisture and perhaps other factors had occurred.
