Abstract: An investigation entitled “Growth and yield of bulbs of Onion (Allium cepa L.) as influenced by different levels of Nitrogen, Phosphorous, Potassium and Sulphur†was conducted during 2016-17 in Randomized Block Design (RBD) with three replication to assess the impact of NPK and sulphur doses on growth and yield of bulbs of Onion. Total ten treatments were tried and it was concluded that the dose of 100 kg N +50 kg P2O5 +50 kg K2O + 45 kg sulphur ha-1 was found to be superior in terms of all growth parameters, yield and yield attributing character of Onion in profitable manner as compared to control and further treatments. The various growth, yield and yield attributing parameters i.e. plant height (39.03 cm), number of leaves plant-1(12.93), diameter of stem (0.91 cm), length of longest leaves (29.57 cm), neck thickness (0.91 cm), shell thickness (0.22 mm), bulb diameter (5.31 cm), length of bulb (4.89 cm), weight of bulb (53.40 g), fresh yield of bulb plot-1 (7.61 kg), marketable yield of bulbs (250.33 q ha-1), TSS content in onion juice (15.67%), were observed with highest mean values and minimum under control i.e., plant height (28.50 cm), number of leaves plant-1 (8.00), diameter of stem (0.62 cm), length of longest leaves (17.83 cm) at 90 DAP near to harvest and neck thickness (0.64 cm), shell thickness (0.12 mm), bulb diameter (2.69 cm), length of bulb (2.56 cm), weight of bulb (34.00 g), fresh yield of bulb plot-1 (4.84 kg), marketable yield of bulbs (158.00 q ha-1), TSS content in onion juice (10.07%) at harvest.
