A field experiment was conducted during 2009–10 and 2010–11 at Meerut, Uttar Pradesh, to study the effect of different herbicides and nutrient management practices on weeds and productivity of wheat (Triticum aestivum L.). In this experiment, 4 nutrient levels viz.; control (No NPK), 50% NPK + FYM 15 t /ha, 75 % NPK + FYM 10 t /ha and 100 % NPK and 5 weed control measures viz.; Pendimethalin 1.0 kg /ha, Fenoxaprop + metsulfuron-methyl (100 + 4 g/ha), Fenoxaprop + carfentrazone (100 +10 g/ha), two hand weeding (25 & 45 DAS) and weedy check. Combined application of 75 % NPK and farmyard manure10 t /ha significantly improved wheat yield and soil nutrient status. The highest grain and straw yields were recorded with application of 75 % NPK + FYM 10 t /ha, which was at par with 100% NPK. Farmyard manure acts as a nutrient reservoir and releases nutrients slowly expected to be more closely matched with supply and demand by the crop. Among the weed control treatments gave significantly higher grain yield compared to weedy check. The highest grain yield were obtained from two hand weeding treatment, although this remained statistically at par with Fenoxaprop + carfentrazone (100 +10 g/ha) and both the treatments resulted in an increase of grain yield as compared to weedy check respectively. The highest net returns and benefit:cost ratio were obtained with application Fenoxaprop + carfentrazone (100 +10 g/ha) among the tested herbicide treatments.
