Abstract: The field experiment conducted at research farm, RARI, Durgapura for two consecutive years during rabi seasons 2013-14 and 2014-15. Results revealed that hand weeding recorded the lowest weed dry matter of 173.04 kg/ha at harvest stage than rest of the treatments. Sulfosulfuran @ 25 gm a.i./ha, clodinafop-propargyl 15 % + metsulfuran methyl 1 % @ 64 g a.i. /ha, sulfosulfuran 75 % + metsulfuran methyl 5 WG @ 32 g a.i. /ha, carfentrazone ethyl 40 % DF @ 20 g a.i./ha, metsulfuran methyl @ 4 g a.i. / ha, 2,4-D ester @ 0.5 kg/ha as post emergence was found effective herbicidal treatment in reducing weed dry matter production. Yield attributes of wheat were also significantly improved due to different weed control measures. The maximum number of effective tillers per square meter (279), spike length (12.6) and grains/spike (43.6) were achieved under hand weeding and weed free treatment. Clodinafop-propargyl 15 % + metsulfuran methyl 1 % @ 64 g a.i. /ha also enhanced these characters by 27.7, 24.2, 74.7, 31.6 and 7.1 per cent, respectively over weedy check and stood as the next best herbicidal treatment. Further, none of the applied herbicides/mixtures in rabi season (wheat) had residual toxicity on plant height of succeeding crops (pearlmillet, mungbean and clusterbean) grown in kharif season.
