A field experiment was carried out at experimental farm, faculty of agriculture, Wadura, SKUAST-Kashmir (J&K) during Rabi 2015-16 to study the effect of sowing dates and nitrogen levels under rainfed conditions of Kashmir. Experiment was conducted in split plot design, keeping three sowing dates (D1-15th October, D2-30th October and D3-15th November) in main plots and four nitrogen levels (N0-0 kg N ha-1, N1-50 N ha-1, N2-100 N ha-1 and N3-150 N ha-1) and was replicated four times. The results revealed that grain yield decreased by 10.6 % from D1 to D2, 7.6 % from D2 to D3 and 17.4 from D1 to D3. Growth characters like plant height (94.94 cm), dry matter accumulation (110.7 q ha-1), tillers m-2 (311.5), leaf area index (3.60) and yield attributes like effective tillers (275.93), grains spike-1 (40.14) and test weight (2.52 g) were recorded highest with 15th October sowing. Increasing N levels results in increase in growth characters, yield attributes and yield and highest valves were recorded with application of 150 kg N ha-1 (N3) however, remained statistically at par with 100 kg N ha-1 (N2). The study finally concluded that delay in sowing reduces the grain yield, while as irrespective of sowing dates, application of 100 Kg N ha-1 to crop resulted in higher growth, yield attributes and yield of wheat as compared to other nitrogen levels, further increase in N application beyond 100 Kg N ha-1 showed non-significant increase.
