| Abstract | ||||
| Two field experiments were conducted in naturaly infested fields with broomrape (Orobanche crenata Fmk.) 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 cops being fenugreek, lupine, flax, coriander and turnip and In the second averred is to study the effect of varieties (Misr I and Giza 40) and four Orobanche contra treatments (glyphosate, imazapic, hand pulling and Untreated check) On controlling Orobanthe, yield and its components In faba bean. Raba bean variety (Misri) caused deceased number and dry weight of Orobanche spikes by 17.3, 17.0 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 (Mal) increased seed yield by 175.0 and 192.9 %, respectively, in both seasons as compared with variety (Giza 40). Al studied trap cops decreased significandy 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 puling and fenugreek were (87.3 & 86.9 and 63.6 & 65.7), respectively, in both "season. What, hand pilling and fenugreek decreased signthcandy dry weight of broomrape spikes/mi 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 bcth seasons compared to untreated plot. The Interaction between varieties and trap cops 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 Pro 40) deceased the number and dry weight of Orobanche spikes by 51.4 and 60.7 % respectively, in 2005/06 season. Also, faba bean variety (Merl) recorded highest values of yield and yield components characters than (Giza 40) variety. For seed yield, fate bean variety (Merl) increased seed yield by 308.3 and 66.7 %, respectvely, in both seasons as compared with (61a 40) variety. On the other hand, as Orobanche control treatments deceased significantly number and dry weight of Orobanche spikes and increased significantly yield and yield component characters In both seasons. Seed yield increased by al 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. | ||||
