abstract={A field experiment was conducted from June to December during 2010/11 crop season at HARC to study the effect of herbicides rates on weed dynamics and yield of wheat (<i>Triticumaestivum</i> L.) variety ¡°HAR 604¡± in randomized complete block design with three replications. the herbicides rates: clodinafop-propargyl(0.065,0.080, 0.105kgha<SUP>-1</SUP>) and isoproturon (1.00, 1.25, 1.50kgha<SUP>-1</SUP>), hand weeding at tillering and weedy checkwere used. The crop was infested with <i>Avenafatua</i>L<i>. </i>and <i>Phalarisparadoxa</i>L<i>. </i>among grass weeds and<i>Cayluseaabyssinica</i>Meisn<i>,</i><i>C. trigyna</i>L<i>.,</i><i> </i><i>Chenopodium album </i>L.<i>,</i><i> </i><i>Corrigoialacapensis</i><i> </i>Wild<i>,</i><i> </i><i>Guizotiascabra</i>(Vis) Chiov<i>, Oxalis latifolia</i>HBK<i>,</i><i> </i><i>Polygonumnepalense</i>L<i>., Raphanusraphanistrum</i>L<i>.,</i><i> </i><i>Spergulaarvensis</i>L. and <i>Tagetesminuta</i> L. among broadleaved weeds. Hand weeding followed isoproturon at 1.50 kg ha<SUP>-1</SUP> significantly reduced density and dry weight of weeds. Among herbicides, isoproturon provided better control of broadleaved and total weeds, whereas; clodinafop-propargyl proved better than isoproturon in controlling grass weeds. Hand weeding and hoeing at tillering resulted in lowest weed dry weight. Highest grain yield (2289.4 kg ha<SUP>-1</SUP>) in was recorded in hand weeding followed by isoproturon at 1.5kg ha<SUP>-1</SUP> (2177.3 kg ha<SUP>-1</SUP>). The highest straw yield was recorded in hand weeding followed by isoproturon 1.50 kg ha<SUP>-1</SUP>, and harvest index was also maximum with hand weeding. Maximum N-uptake was also recorded in these treatments. Post emergence herbicides and /or hand weeding and hoeing at tillering can further enhance the weed suppressive effect of the crop.},
