AbstractA field study was carried out during the winter season of 2005 – 2006 at the farm of field crops department , Collage of Agriculture , University of Baghdad, Abu Ghraib, to study yield and yield components of four varieties of Broad bean (Spanish, Cyprus, IPA, Ekwadilgy) and study the effect of herbicides (Paraquat , Ronstar) on weed plants growing at broad bean field the results indicated that the treatments hand weeding, Paraquat, and Ronstar redused the number of narrow leaved weeds by 90% , 87% , 85.6% and broad leaved weeds by 82.8% , 58.6% , 66.1% respectively. And redused the number of weeds both narrow and broad leaved by 86.1% , 70.2% , 72.0% respectively. Ronstar redused number of Betavulgaris, Sweet clover, Button weed, Rigid rye grass, Milk thistle, Annual darnel, Common bishop weed, Field bind weed, Bur weed by 41.5% , 67.9% , 65.5% , 88.8% , 100% , 100% , 100% , 87.5% , 100% respectively. Paraquat redused the number of same weeds by 28.8% , 55.5% , 62.7% , 66.6% , 86.7% , 100% , 100% , 100% , 100% , and wild oats not affected. Ronstar Paraquat redused at the total dry weight of weeds by 51.3% , 49.5% respectively compare with control. And Cyprus variety was significant at pods / plant (10.62) , Ekwadilgy was significant at seeds / plant (45.26) unless the variety Spanish and this variety was significant at weight of 100 seeds (145. 2 gm) and the yield of seeds per hectare (4.024 Km / h) but this significant was only from the variety IPA that gave les value at all characters under study.
