Two field experiments were carried out at the Agricultural Research and Experimental Center, Lac, of Agric. Moshtohor Kalubia, Egypt, during 1985/86 and 1986/87 seasonn, to study the effect of planting methods, plant densities and weed control treatments, plant densities and weed control treatments on controlling the associated weeds with (faba bean. Each experiment included 30 treatments which were the combination of two planting methods, three plant densities and five weed control treatments. The results indicated that Herati (wet) method decreased number of weeds/rn2 at 45 and 90 days from (aba bean planting, but did not affect fresh and dry weight of weeds/rn’ compared with Afir (dry) method. Increasing plant densities up to 280000 plants/fed, decreased number, fresh and dry weight of weeds especially, after 90 days from planting. The lowest number, fresh and dry weight of weeds/rn’ at 45 days from planting was recorded by topogard (1.5 kg/fed.) and prometryn (1.0 kg/fed.), while the hand weeding treatment gave the best contrelling effect after 90 deys from planting followed by topogard. The effect of inter actions were significant only on number of and topogard with Herati which gave the lowest number of weeds/n’ after 45 and 90 days from planting. |
