A field investigation was conducted during Rabi 2008–09 and 2009–10 to study the response ofsowing time and nitrogen scheduling in wheat (Triticum aestivum L.) on its growth and yield underlate sown conditions at Faizabad (UP). The treatments comprised of three sowing dates [5th , 15thand 25th December] and six nitrogen (N) schedules [N0 (control); N1kg N at first irrigation; N2 – 50 kg N at sowing time + 50 kg N at first irrigation + 50 kg N at anthesis;N3 – 37.5 kg N at sowing time + 75 kg N at first irrigation + 37.50 kg N at anthesis; N4 – 50 kg N atsowing time + 50 kg N at first irrigation + 50 kg N at IInd irrigation; N5sowing time] replicated four times in split plot design. Both sowing dates and N schedulessignificantly affected the initial plant population, plant height, number of shoots m–2, number ofspikelets per spike, 1000–grain weight and grain and straw yields. In case of sowing dates,significantly maximum grain yield (32.6 and 33.4 q ha–1) was obtained where sowing of wheat wasdone on 5th December. Among N schedules, N3 gave significantly maximum yield (35.6 and 37.4 qha–1) during both the years.– 75 kg N at sowing time + 75– 100% N as basal dose at
