A field experiment was carried out at Agronomy Research Farm of Narendra Deva University of Agriculture and Technology, Narendra Nagar (Kumarganj), Faizabad (U.P.) during Rabi season of 2014-15 to study the response of late sown wheat varieties to different nitrogen management practices. Twenty treatment consisted of five doses of nitrogen (90 kg N ha-1, 120 kg N ha-1, 90 kg N ha-1 + 25% N through FYM, 120 kg N ha-1 + 25% N through FYM, 150 kg N ha-1) and four varieties of wheat (HD-2643, HUW-234, PBW-373 and HD-2285).The experiment was conducted in Randomized Block Design (R.B.D.) factorial with three replications on silt loam having low organic carbon (0.38%), nitrogen (204 kg ha-1), medium in phosphorus (15.35 kg ha-1) and potassium (267 kg ha-1). The growth characters like plant height, dry matter accumulation, number of tillers, leaf area index were significantly higher under 150 kg N ha-1 being at par with120 kg N ha-1 + 25% N through FYM over rest of the levels and among the varieties PBW- 373 was at par with HD-2285 while significantly superior over HP-2643 and HUW-234. The yield components like number of ears per meter row length, ear length (cm), number of grain ear-1, grain weight ear-1 (g) grain yield (kg ha-1), straw yield (kg ha-1) and nitrogen uptake at harvest (kg ha-1) were maximum under 150 kg N ha-1 which was at par with 120 kg N ha-1 + 25% N through FYM and among the varieties PBW-373 being at par with HD-2285 with respect to the yield components while grain yield (kg ha-1) and straw yield (kg ha-1) was maximum under PBW-373 followed by HD-2285. Harvest index and 1000-grain weight (g) were not influenced significantly due to nitrogen management practices and varieties. Thus it may be concluded that nitrogen management practice of 150 kg N ha-1 proved as the most suitable practice for exploitation of the yield potential of late sown wheat. Among the varieties PBW-373 and HD-2285 were found most suitable for cultivation under late sown condition for achieving higher yield and economics.
