Two field experiments were conducted in the Experimental Research Station of the Faculty of Agriculture. Cairo University at Giza during 2000/2001 and 2001i2002 seasons to explore the effects of four sowing dates on yield and yield components of six faba bean cultivars. The four sowing dates were ranged from mid October to first December at 15 days interval. The cultivars belonged to various seed sizes and origins. These cultivars included 3 Egyptian improved cultivars and 3 exotic ones. The results showed that mid November seemed to be the appropriate sowing date for the Egyptian cultivars. The exotic cultivars varied in their responses to various sowing dates. The exotic cultivars Minica and Kristall are more adapted to delaying sowing to first December, whenever low temperature predominate. Mid November was the most proper for the exotic cultivar PBL 938. The early sowing dates. before mid November. had negative effects on the performance of all studied cultivars for most investigated traits.
