| Abstract | ||
| A field trial was conducted during winter sesons of 2008-2009 at experimental farm of the Department of Field Crop Science , College of Agriculture , Abu-Ghraib , University of Baghdad . The objectives of the study was to evaluate activity of Herbicides, Chevalier , Topic and Logron on weeds and grain yield of wheat var (lba99) , Chevalier reduced number of broad and narrow leaf after 30 , 60 , 90 days , after application of herbicides at both season by 88.3% , 92.2% , 88,3% , 92.3% , 86.1 and 90.6% respectively according to weedy treatment also gave lowest dry weight of weed , 16.6 , 10.5 , 17.6 and 9.6 gm.m-2 while the weedy treatment gave highest value of dry weight of weed , were 176.5 and 181.4 gm.m-2 so the chevalier reduced the dry weight of weeds at first season by 90.6% and 91.0% and second season by 90.3% and 92.2% respectively according the weedy treatment , The wheat positively respond and gave high value at both season as high plant 103.7 and 105.8 cm , number of spik per meter 403.4 and 429.2 and number grain per spike 57.6 , 58.2 respectively , therefore they caused increasing yield of grain at first season by 45.5% and second season 45.2%. | ||
