Abstract: A field experiment “To study the interactive effect of age of seedling and plant spacing on growth and yield of onion bulb (<em>Allium cepa</em> L.) Cv. Pusa Red’’<strong> </strong>was conducted at the experimental field of AKS University, Satna, Horticulture research farm, during the period October 2016 to March 2017. This growth observations was significantly influence by the age of seedlings, 45 days old seedlings brought about significantly higher plant height (44.92 cm), number of leaves (8.74), length of leaves (42.68 cm), width of leaves (1.29 cm), fresh weight of leaves (97.71 g), dry weight of leaves (21.20 g), fresh weight of bulb (99.89 g), diameter of bulb (6.67 cm) and bulb yield (290.47 q/ha) as compared to 25 and 35-days old age of seedlings. The increase in plant density up to 20x20 cm resulted in significantly higher plant height (42.58 cm), number of leaves (7.84), length of leaves (40.38 cm), width of leaves (1.07 cm), fresh weight of leaves (83.34 g), dry weight of leaves (16.79 g), fresh weight of bulb (81.41 g), diameter of bulb (5.53 cm), bulb yield (274.40 q/ha) as compared to closer 20x15 and 20x10 cm density.
