A field experiment was carried out during rabi season of 2021-22 and 2022-23 in the Instructional Farm, Krishi Vigyan Kendra, Indira Gandhi Krishi Vishwavidyalaya, Raigarh (C.G.), Performance of wheat varieties under different nutrient management on growth, yield attributes and yields under late sown condition. The experiment was laid out in split plot design with three replications with keeping three varieties i.e. V₁ – Chhattisgarh Genhu-4, V₂ – Chhattisgarh Amber Wheat, V₃ – GW-366 as main plot and six nitrogen management i.e. N₁ – 50% RDN basal + 50% top dressing, N₂ – 50% RDN basal + 50% top dressing + FYM @ 5 t ha^-1, N₃ –50% RDN basal + 50% top dressing + FYM @ 5 t ha^-1 + Azotobacter + PSB culture, N₄ – 50% RDN basal + 50% top dressing + vermi compost @ 01 t ha^-1, N₅ – 50% RDN basal + need based application through leaf colour chart, N₆ – 50% RDN basal + foliar application of nano urea at 35, 50 & 65 DAS as sub plot treatments. The result revealed that the all growth parameters (plant height, number of tillers and dry matter accumulation), yield attributes (effective tillers, number of grains earhead^-1 and 1000-grains weight), grain, straw yield and harvest index were significantly the highest under V₁ – Chhattisgarh Genhu-4. The shortest value of these above characters was recorded with GW-366 of wheat variety. As regards to nitrogen management in wheat, treatment N₄ – 50% RDN basal + 50% top dressing + vermi compost @ 01 t ha^-1 registered significantly the highest all growth parameters (plant height, number of tillers and dry matter accumulation), yield attributes (effective tillers, number of grains earhead^-1 and 1000-grains weight), grain and straw yield and harvest index. The lowest value was recorded under N₁ – 50% RDN basal + 50% top dressing.
