In order To study the efficacy of different doses of Imazethapyrherbicides to control weeds and seed hydro"=priming Chickpea experiment rainfed crop year 2015--2016 at the Agricultural Research Station of Lorestan University in a factorial Randomised Complete Block Design with three replications Was conducted. The first factor in two levels (seed hydro"=priming and non"=priming) and second factor at six levels of the Imazethapyr herbicide in concentrations of 250, 500, 750, 1000 cc and weeding and non"=weeding. The interaction effect meaningful seed yield, dry matter yield and performance of herbicides on weed density in 30 days after spraying at \mbox{1\,\%}, So, respectively, as well as other traits at \mbox{5\,\%}. The highest herbicide efficacy on dry weight of weeds and weed density (67/\mbox{14\,\%} and 71/\mbox{37\,\%}) at 15 days after spraying, in treatments (1000 cc Imazethapyr + non"=priming and 250 cc Imazethapyr + non"=priming) Was observed. The highest herbicide efficacy on dry weight of weeds and weed density (87/\mbox{37\,\%} and 91/\mbox{80\,\%}) at 30 days after spraying, in treatments (500 cc Imazethapyr + priming and 750 cc Imazethapyr + non"=priming) Was observed. The highest seed yield (\mbox{873\,kg}) of treatment (weeding + priming) was observed. The highest forage yield (948/\unitfrac[20]{kg}{ha}) in treatment (250 cc Imazethapyr + non"=priming) was obtained. The highest number of branches (6.5) in treatment (750 cc Imazethapyr + non"=priming), was obtained. The highest plant height (\mbox{26.2\,cm}) in the treatment (weeding + non - priming) was obtained. In this experiment could Imazethapyr herbicides to control weeds, on the other hand the negative effects it causes slow growth, severe burning plant and a decrease in grain yield, so it is recommended that these herbicides can be used in dry conditions.}
