Abstract:
The present investigation entitled “Effect of weed management practices on growth and yield of wheat (Triricum aestivum) crops” was conducted at Agronomy Research Farm, Rama University Mandhana, Kanpur (U.P.) during Rabi season of 2021-22. The experiment was laid out in Randomized block design with three replications keeping eight weed management practices Prosulfocarb 80 EC (PE) 1600 ml/ha, Prosulfocarb 80 EC (PE) 2000 ml/ha, Prosulfocarb 80 EC (PE) 3000 ml/ha, Sulfosulfuron @ 25g/h, Clodinopop+Metsulfuron @ 60+4 gm. a.i./ha, Sulfosulfuron+Metsulfuron @30+4 gm.a.i./ha, Weed free up to 60 days, Weedy Check. Results revealed that among weed management practices weed free follewed by Sulfosulfuron (30g) + metsulfuron (4g) a.i ha-1 proved as superior than other treatments with respect to higher crop growth and yield attributes where as weed density, plant height, leaf area index, grain and straw yield. Maximum gross return and cost of cultivation was found with weed free treatment combination. While maximum net return was found with Sulfosulfuron (30g) + metsulfuron (4g) a.i ha-1. Maximum B:C ratio was obtained in combination of Sulfosulfuron (30g) + metsulfuron (4g) a.i ha^-1. The planting was done on 4th december 2021. Amoung the various weed management treatment Sulfosulfuron (30g) + metsulfuron (4g) a.i ha^-1 recorded higheat B:C ration and yield.
