Intercropping of two cultivars of soybean, especially those of different growth types, may cause increase in production, mainly due to better use of required sources for growth. In a field experiment, seed yield of two soy bean cultivars which differed in some morphological characteristics were investigated at Khoy Agricultural Research Station. A split plot design with 3 replications was used. Main plots were consisted of 3 plant densities of 20, 33 and 50 plants m-2, sub-plots were allocated to 5 intercropping ratios of Williams and Clark cultivars. The results indicated that plant height, number of sub branches and first pods height were affected by plant density and intercropping ratio of 2 cultivars. Pod number per plant and 1000 seed weight were the most important yield components and showed a positive correlation with plant density and intercropping ratios, but number of seeds per plant was not affected. The highest seed yield (4615 kgha-l) was obtained from 50:50 ratio of two cultivars in 50 plants m-2 density which had a land equivalent ratio (LER) above 1.10.
