Field experiment was conducted at Sher-e-Kashmir University of Agricultural Science and Technology, Kashmir, during kharif season, 2015 and 2016 with the objective to study the growth and yield of maize under variable planting time and nitrogen levels and to simulate trends of maize production. Experiment was laid in Split-Plot design assigning three planting dates 22nd May, 30th May, 8th June to main plots and four Nitrogen Levels 80kg, 120kg, 160kg, 200kg to Sub-plots. Maximum energy was consumed  in   Sowing maize on 30th May  with 160kg nitrogen level  was 16711.72 MJ.  Sowing maize on 30th May gives highest net returns of Rs. 106591.0 and 108952.5 with a B.C ratio of 2.62 and 2.67 was recorded with 160kg nitrogen level which was followed by 200kg with net returns of Rs. 103901.0 and 106244.5.As far as enery is concerned highest input was observed with nitrogen level of 200Nkha-1(16711.72) As far as energy output were also observed to follow the same trend with planting on 8th June and 160 kg Nha-1 (115530.96 and 114334).

Key words: Maize, Spacing, Date of sowing, Energy, MJ, Energy input, Energy output, Economics B.C ratio.
