The field trials were conducted during rabi season 2012-13 to 2014-15 at Vegetable Research Farm, CCS HAU, Hisar, India to evaluate the response of sulphur sources (gypsum and elemental sulphur) and doses (0, 15, 30 and 45 kg/ha) on yield, quality, storability as well as economic returns of onion (Allium cepa L., cv. ‘Hisar Onion- 4’). Across different sulphur sources and levels, bulb yield increased by 7.02 to 16.66% as compared to those of the plants that received no sulphur. Application of gypsum at 30 kg/ha resulted in the highest bulb yield (245.34 q/ha), benefit cost ratio (2.43) and relatively lesser physiological loss of weight (20.34%), rotting (8.32%) and sprouting (15.24%), but was not significantly different with sulphur applied at 45 kg/ha. The maximum uptake of nitrogen, phosphorus, potassium and sulphur was also observed in bulbs treated with 30 kg gypsum/ha. Sulphur in the form of gypsum at 30 kg/ha may be recommended for better nutritional status and economic return of onion crop under sandy loam soil conditions.
