The present piece of research work was carried out for two consecutive years during kharif 2020 and 2021 to determine the effect of varying planting dates and nitrogen levels on the performance of maize composite variety Suwan-1. The experiment included three dates of sowing viz. S₁= 28^th April (17^th Standard Meteorological Week), S₂= 13^th May (20^th SMW) and S₃ = 28^th May (22^nd SMW) with four levels of Nitrogen viz. N₁ = 90 kg ha^-1, N₂ = 120 kg ha^-1, N₃ = 150kg ha^-1 and N₄ = 180 kg ha^-1 was laid out in a Factorial Randomized Block Design with three replications. The results of the experiment revealed that highest nitrogen uptake for both the years in both grain and stover was observed under first sowing date of 28^th April with the combination of 150 kg ha^-1 of nitrogen. However, nitrogen content was found to be insignificant during both years.
