Broomrape is a determining factor for faba bean cultivation in Egypt especially under sandy soil conditions. For this reason two field experiments were conducted in naturally infested fields with broomrape under sandy soil conditions at lsmailia Agricultural Research Station, Ismailia governorate during 2014/15 and 2015/16 winter seasons to study the effect of degree interaction between three faba bean varieties namely Giza 843, Misr3 and Giza 3, two seeding rates at 30 and 60kg seed/fed. and two broomrape control treatments namely Roundup twice at 75 seed/fed. and untreated check on broomrape management and faba bean productivity. A split split plot design with three replicates was used, faba bean varieties were assigned to the main plots and seeding rates were allocated in sub plots, while weed control treatments were distributed randomly in sub sub plots. Results revealed that both faba bean varieties Misr3 and Giza843 exhibited significant decrease in numbers and weight of broomrape spikes/m2 estimated by 87.0 and 91.0% & 49.2 and 53.3 % in 2014/15 winter season and by 86.I and 90.6% & 47.9 and 54.5 % in 2015/16 winter season, respectively as compared with the susceptible variety Giza 3. Faba bean varieties Misr3 and Giza843 significantly increased faba bean yield and its components in both seasons as compared with variety Giza 3. Seed rate of 30kg/fed. significantly decreased the number and weight of broornrape spikes/m2 by 16.8 and l l.5°/o in 2014/15 winter season and by 15.3 and 18.0% in 2015/16
winter season, respectively as compared to seed rate of 60kg/fed.
