Abstract: A field experiment was conducted during rabi season of 2014-15 and 2015-16 at Krishi Vigyan Kendra, Bahraich (Uttar Pradesh). Significantly lower weed density, dry matter accumulation and nutrient uptake by weeds was recorded with variety ‘K-1006’ as compare to ‘HD-2967’, 'NW-5054', 'DBW-39', 'CBW-38' and 'DBW-17'. Variety 'K-1006' produced significantly higher grain yield (52.12 q ha-1) and straw yield (70.60 q ha-1) over rest of the wheat varieties. Among the herbicidal treatments, post emergence application of sulfosulfuron reduced the density and dry weight of weeds, and uptake of nutrient by weeds. This treatment also gave the higher grain (49.4 q ha-1) and straw yield (68.5 q ha-1), which was on par with metribuzin. Weed free upto 60 DAS recorded significantly higher values of yield attributes, grain yield (53.0 q ha-1) and straw yield (71.5 q ha-1). This treatment had the lowest nutrient uptake by weed as compare to rest of the treatments. Variety ‘K 1006’ had the maximum net return (Rs. 53.9x 103) and benefit :cost ratio which was followed by variety ‘HD 2967’ with with net profit of (Rs. 498x103) and benefit cost ratio of 1.6.
