The field experiment was conducted during the rabi season of 2015-16 at Campus for Research and Advance Studies Dhablan, Patiala to evaluate the response of yield and yield attributes of barley (Hordeum vulgare L.) to date of sowing and nitrogen levels. A set of 12 treatment combinations including three dates of sowing viz., 20th October (D1), 16th November (D2) and 10th December (D3) in main plot, and nitrogen control, @ 30 kg ha-1, 60 kg ha-1, 90 kg ha-1 in sub plot were applied. The results showed that the crop sown on 20th October and 16th November attained statistically similar plant growth characters (in terms of plant height and dry matter accumulation). Crop sown on 20th October received significantly higher effective tiller (364.69 m-2) then other date of sowing (16th November (358.61 m-2) & 10th December (347.66 m-2)). Crop sown on 16th November resulted better yield attributes (Spike length, Number of grains per spikes and test weight) than the 20th October and 10th December. Different date of sowing significantly affects the yield and a yield attributes of barley. Grain yield found to be significant with crop sown on 16th November, however biological yield significant crop sown on 20th October. Application of 90 kg nitrogen per hectare resulted in improvement in most of the growth parameter. Application of 90 kg nitrogen per hectare resulted in improvement in most of yield attributes (Spike length, Number of grains per spikes and test weight). Grain and biological yield significant increase with each increasing in Nitrogen level up-to 90 kg ha-1.
