Performance of orobanche control treatments in faba bean crop [electronic resource].

Includes references.

Evaluation of ten treatments for the control of Orobanche of faba bean was made in two field experiments carried out at Sids Agricultural Research Station, Beni-Suef Governorate. The results indicate that the variety Giza 2 had the highest number of Orobanche plants (53.3 spikes/m2 ). In contrast, late sowing, glyphosate application, integrated control, non- chemical integrated control and Giza 429 (Orobanche tolerant var.) had the lowest number of Orobanche, which ranged from 5.3 to 10.3 spikes/m2. These five treatments showed areduction in number of Orobanche/m2 relative to Giza 2, of 90, 81, 88, 87 and 87%, respectively. The results indicate also that non-chemical integrated control treatment gave the highest faba bean seed yield of 1046 kg/fed (6.8 ardab/fed) followed by integrated control treatment (995 kg/fed, i.e 6.4 ardab/fed) with no significant difference. Both treatments produced seed yield 50 and 48 times greater than Giza 2, respectively. Late sow- ing ranked as the third highest yield treatment with seed yield of 648 kg/fed (4.9 ardablfed) that was 37 times the yield of Giza 2, while Giza 429 was the fourth highest yielding treatment. These treatments in gen- eral, and the two integrated control treatments in particular, had also the highest yield component characters.
