Integrated Broomrape (Orobanche crenata Forsk.) Control in Faba Bean (Vicia faba L.) with Nitrogen Fertilizer, Intercropping and Herbicides

摘要

TWO FIELD experiments were carried out at the farm of Sakha Agricultural Research Station, Kafreishiekh, Egypt, during 2010-2011 and 2011-2012 faba bean growing seasons (Latitude 30° 48' N, Longitude 31° 35'E). The trials studied integrated broomrape (Orobanche crenata Forsk.) control in faba bean cv. Giza 843 with nitrogen fertilizer, intercropping faba bean (Vicia faba L.) with oat (Avena sativa L.) or fenugreek (Trigonella foenum-graecum L.) and herbicides. Herbicide treatments were: 1- Untreated, 2- Glyphosate (48% WSC) at 36 g a.i./fed., (fed = feddan= 0.42 hectare),(once)., 3-Glyphosate (48% WSC) at 36 g a.i./fed. (twice)., 4- Imazapic (10 % EC) at 20 g a.i./fed. (once), 5- Imazapic (10 % EC) at 20 g a.i./fed. (twice). Sub-plots were assigned to faba bean (sole crop), intercropping (faba+ oats), (faba+ fenugreek) and nitrogen fertilizer with ammonium nitrate (NH_4N0_3).
