Abstract: A field experiment was conducted during summer rain (kharif) season of 2017-2018 at research instructional farm, AKS University Sherganj Satna Madhya Pradesh. An experiment was entitled “Effect of nitrogen level and spacing on growth, yield and quality of kharif onion (<em>Allium cepa</em> L.) Cv. N-53”. The experiment consisting of twelve treatments with plant spacing as well as nitrogen level (0, 40, 80 and 120kg/ha. was laid out in Randomize Block Design with three replication. Growth parameter different significantly at all stage of crop growth were maximum plant height (22.73, 48.81 and 60.31cm) at 30, 60 DAT at harvest and number of leaves (8.03, 10.89 and 13.51) 30, 60 DAT and at harvest were recorded in the 120kg /nitrogen. Thickness of neck, Fresh weight, Dry weight of leaves and yield attributes viz., Bulb diameter, height of bulb, fresh weight of bulb, dry weight of bulb &amp; total yield (g) plots, TSS and quality of onion are significant. The both factors nitrogen and spacing of onion (120kg/N₃ and 15x20cm) S₃ weresignificant. It was observed that spacing’s <em>i.e.,</em> 15x20cm significantly improved growth and yield of onion.
