Abstract
Weed contol study on fallow field was condected during growing season 2009/2010 at field of agriculture college,Mosul university to determine the efficiency of different weed control methods (plowing by disk plow,sprayind paraquat herbicide,plowing and spraying), the frequency of controlling (once,twice) and the duration time of weed samples taken from the field (13 April,27April,11May) on narraw and broadleaf weed control in dry land farming,The results showed that a significant effect for treatment(disk plow+paraquat herbicide)and plowing by disk plow. They achieving highest weed control percentage for broadleaf and narrow weed were up to 99.12% ,98.93 % respectively, where it was noted a clear reduction for broadleaf weed density and dry weight up to zero plant/m2 and zero g/m2 ,Weed control by (disk plow + paraquat herbicide) gave lowest dry weight up to 0.22 g/m2 and density 1.83 plant/m2 for narrow weed.Plowing once by disk plow has surpassed significantly by achieving highest field efficiency for equipment 1.81 D/hr.The results also showed that controlling for twice time gave a significant decrease in weed density and dry weight and increasing weed control percentage with a significant decreas in actual productivity of the equipment while weed sampling in 13/April recorded highest weed dry weight and density but its̓ surpassed significantly by achieving highest weed controlling percentage up to 67.62%.
