Abstract
A field experiment was conducted during winter seasons of 2004/2005 , 2005/2006, and 2006/2007 at experimental farm of the Department of Field Crop Sciences, College of Agriculture , Abu-Ghraib , Baghdad . Soil texture was a silty clay loam classified as Typic Torrifluvent The objectives were to investigate performance of bread wheat cv. Abu-Ghraib under levels of irrigation water \|6230 m3.ha"', 4670m3.ha1-, 3120m3.ha1- and 1555 m3.ha1- and herbicides [diclofop-methyl , Logran, and Chevalier]. A split - plot design arrangement used with three replications. Herbicides diclofop-methyl,Logran, and Chevalier reduced number of weeds by 50.9 % , 53.4 %, and 95.9 % respectively in comparison to control. Herbicide diclofop-methyl reduced number of narrow leaved weeds by 96.3 %, while Logran reduced the number of broad leaved weeds by 92.9 % . The herbicides diclofop-methyl, Logran , and Chevalier caused consumption of the amount of water as 88.6 m3.ha', 86.2 m3.ha1- and 14.6 m3.ha1- while the treatment of control caused high consumption of amount of water 223.3 m3.ha'' therefore , those herbicides reduced consumption of the amount of water by 60.3 % , 61.4 % , and 93.5 % respectively as compared to control. The interaction of levels of irrigation water and herbicides was significant . Treatment of level of water applied 1555 m3.ha1- with plants gave lower of consumption of amount of water 70.3 m3.ha1- by weeds and 86.2 m3.ha1- by wheat.
