The present study was conducted at the Experimental Farm, Faculty of Agriculture, Assuit University, Assiut, during  autumn of 2004 and 2005 seasons to study the effect of sowing date and plant spacing on dry seed yield (pulse) in three common bean cultivars (Phaseolus vulgaris L.) (Giza 6, Swiss Blanc and Nebraska).  Plant spacings tested were 10, 20 and 30cm. Significant differences among cultivars were found in most studied traits. Nebraska cultivar was the earliest to produce mature dry seeds, gave the greatest records for pods/plant, dry seed yield/plant and the highest calculated seed yield/fed. Plants sown on Sept., 15, Sept., 18 gave the best potential for number of pods/plant, percentage of final plant stand,   percentage of seed germin-ation and seed yield /plant. Plants sown at 10 cm gave the highest values for dry seed yield (kg/fed.). Plants sown at 30 cm gave the highest values for percentage of final plant stand, pods/plant, and seed yield/plant.
