Field experiment was conducted for two consecutive seasons (2008/09-2009/10) at the Demonstrated Farm, Sudan University of Science and Technology, Sudan, to study the effect of seed rates on growth, and yield, of three genotypes of soybean (Glycine max.L.). Treatments were three genotypes G1 (Egyptian), G2 (1448-2E (M)) andG3 (1905-2E (M) and seed rate were SR1 (48.000seedha-2 , one seed /hole one side), SR2(195.000seedha-2 , two seeds/hole two sides) and SR3 (146.000seedha-2 , three seeds/ hole one side ).The experiment was designed in randomized complete block design, with two factor genotypes arranged in main plot, and seed rate in subplot with four replications. The parameters studied were plant height and number of leaves /plant at (30, 45, 60 and 75days) from sowing, dry weight of plant(g), number of pods/plant, number of seed/pods, weight of pods/plant, weight of seed/plant, and yield( kg/ha) The results of the two seasons, showed significant differences between all treatments. Except the number of seed/plant, and weight of pods/plant. Genotype 1418-2E (M) gave higher yield and fresh weight (forage), compared with Egyptian and 1905-2E (M)
