Abstract: Two field experiments were conducted in naturally infested fields with broomrape (Orobanche crenata Forsk.) at Shandaweel Research Station, Sohag governorate during 2004/05 and 2005/06 winter seasons. The aim of this work in first experiment is to study the effect of two varieties (Misr 1 and Giza 40) and five trap crops being fenugreek, lupine, flax, coriander and turnip and in the second experiment is to study the effect of varieties (Misr 1 and Giza 40) and four Orobanche control treatments (glyphosate, imazapic, hand pulling and Untreated check) on controlling Orobanche, yield and its components in faba bean. Faba bean variety (Misr1) caused decreased number and dry weight of Orobanche spikes by 17.3, 17.0, 13.1 and 13.1%, respectively, in both seasons as compared with variety (Giza 40). Also, faba bean varieties gave highly significant increase in faba bean yield and yield components characters in both seasons. For seed yield, faba bean variety (Misr1) increased seed yield by 175.0 and 192.9 %, respectively, in both seasons as compared with variety (Giza 40). All studied trap crops decreased significantly number and dry weight of broomrape spikes and increased significantly yield and its components in both seasons. The highest reduction percentage on number of Orobanche spikes obtained by hand pulling and fenugreek were (87.3 & 86.9 and 63.6 & 65.7), respectively, in both season. While, hand pulling and fenugreek decreased significantly dry weight of broomrape spikes/m2 by 87.8 and 61.8 %, respectively, in first season and by 88.9 and 69.0%, respectively, in second season as compared with untreated plots. For seed yield, the highest values was obtained from fenugreek and coriander by (157.1 & 150.0%) and (200.0 & 200.0%), respectively, in both seasons compared to untreated plot. The interaction between varieties and trap crops gave the highest reduction on number and dry weight of Orobanche spikes and this reflected on yield and its components. In the other experiment, faba bean variety (Giza 40) decreased the number and dry weight of Orobanche spikes by 51.4 and 60.7, respectively, in 2005/06 season. Also, faba bean variety (Misr1) recorded highest values of yield and yield components characters than (Giza 40) variety. For seed yield, faba bean variety (Misr1) increased seed yield by 308.3 and 66.7 %, respectively, in both seasons as compared with (Giza 40) variety. On the other hand, all Orobanche control treatments decreased significantly number and dry weight of Orobanche spikes and increased significantly yield and yield component characters in both seasons. Seed yield increased by all Orobanche control treatments, the highest values was obtained from imazapic and glyphosate by (133.3 & 111.1%), (140.0 and 140.0 %), respectively, in both seasons compared to untreated plot. The interactions between varieties and Orobanche control treatments gave the highest reduction on number and dry weight of Orobanche spikes in both seasons. So, the best seed yield was obtained from the interaction between faba bean variety (Misr 1) with glyphosate and imazapic (6.4 and 6.2 ardab/fed) compared to the interaction between faba bean Giza 40 variety and untreated plot (0.4 ardab/fed) in 2004/05 season. From these results, using some integrated weed management as growing tolerant cultivars (Misr1), some trap crops(fenugreek and coriander) and application imazapic or glyphosate herbicides gave the highest reduction in Orobanche injury and increased faba bean production.
