An average decrease in grain yield by 15.42 % was observed due to season-long weed-crop competition. Lowest monocot and dicot weeds were observed with weed free treatment. The best weed control efficiency in case of monocot (90.8%) and dicot (82.8%) was achieved with metsulfuron-methyl and metribuzin, respectively compared to other herbicides namely pendimethalin, carfentrazone, fenoxaprop and 2,4-D. All the treatments except fenoxaprop, carfentrazone, 2,4-D and mixture of metribuzin and fenoxaprop application gave significantly higher grain yield compared to weedy check. However , higher additional net return (Rs. 31,359) was obtained with metsulfuron-methyl followed by metribuzin (Rs. 30,907).
