Abstract: The field experiment conducted at research farm, RARI, Durgapura for two consecutive years during rabi seasons 2013-14 and 2014-15. Results of revealed that highest weed control efficiencies of 89.4 per cent were recorded with hand weeding at harvest stage. It was closely followed by 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 and pendimethalin pre emergence treatments. N, P and K in grain and straw of wheat were significantly improved due to most of the weed control treatments over weedy check. Weed free, clodinafop propargyl 15 % + metsulfuran methyl 1 % @ 64 g a.i. /ha, sulfosulfuran 75 % + metsulfuran methyl 5 WG @ 32 g a.i. /ha and hand weeding were the superior treatments in this regarded. Further, none of the applied herbicides/mixtures in rabi season (wheat) had residual toxicity on effective nodules and total branches per plant of moongbean crop grown in kharif season.
