The field experiment was conducted during the rabi season of 2018–19 and 2019–20 at Agronomy Research Farm of Acharya Narendra Deva University of Agriculture & Technology, Narendra Nagar (Kumarganj), Ayodhya, Uttar Pradesh to assess the effect of fertility levels and weed management practices on yield attribute and yield of wheat crop (Triticum aestivum L.) The soil of experimental field was silty loam in texture, low in organic carbon and available nitrogen, medium in available phosphorus and available potassium with near to neutral in reaction. There were two factor, 3 fertility levels (100 % DRF through inorganic fertilizer, 75 % RDF through inorganic + 25 % N through FYM and 50 % RDF through inorganic + 50 % N through FYM) and 5 weed control practices (Sulfosulfuron + Metsulfuron @ 30 g a.i. + 4 g a.i. ha^-1, Clodinafop + Metsulfuron @ 60 g a.i. + 4 g a.i. ha^-1, Mesosulfuron + Iodosulfuron @ 12.2 g a.i + 2.2 g a.i. ha^-1, weed free upto 60 Days and Weedy check. The treatments were replicated three times with fifteen treatment combination in a factorial randomized block design. Among the treatments combination 100 % RDF (NPK- 150:60:40) with weed free upto 60 DAS was recorded maximum value of growth and yield attributes e. i. initial plant population m^-2, number of tillers m^-2, plant height (cm), dry matter accumulation (g m^-2), number of effective tillers m^-2, length of spike (cm), number of spikelets spke^-1, number of grains spike^-1 and Test weight. Thus, it may be concluded that application of 100% recommended dose of NPK ha⁻¹ with weed free upto 60 DAS as proved most superior to other treatment with respect to higher yield attributes and yield of wheat crop.
