A three-year experiment was carried out in West Kordofan State during 1999, 2000 and 2001 growing seasons to study the effect of four population densities and four varieties of sorghum on seed yield. The varieties did not show significant difference in the number of days to 50% flowering, but differed significantly in plant height and seed yield per hectare. The effect of plant density on seed yield was significant. All cultivars gave their highest yield under the highest density (125 000 plants/ha), and the variety Wad Ahmed out yielded the other three varieties. The interaction between the cultivar and plant density did not significantly affect the seed yield.
