Two contrasting intercropping systems, sorghum/pigeon peas and sorghum/mung bean, were compared for the effects of intercropping on leaf area index, grain yield, yield components and total dry matter. The yield of sorghum was less affected by intercropping than those of the grain legumes. Between the two grain legumes, relative yield reduction in the intercrops from the respective role crops was more in mung bean than in pigeon pea. Decrease in grain number unit area**-1 was the direct basis for lower grain yields in inter crops than in role crops. Grain size was not affected by intercropping. Intercropping caused reduction only in number of pods in pigeon pea but in both number of pods and number of grains per pod in mung bean.
