Abstract: An experiment was conducted to study the effect of sulphur application on growth, yield and quality of onion at Horticulture Farm of Institute of Agriculture, Visva-Bharati, Sriniketan. The treatments consisted of six incremental doses of sulphur application (10, 20, 30, 40, 50 and 60 kg ha-1) and no sulphur application (control, 0 kg S ha-1). Treatments were arranged in Randomized Block Design with three replications. Yield, yield attributes and most of the other traits of onion (Agrifound Dark Red) response favourably to the sulphur application in a range of 40 to 60 kg ha-1. Graded level of sulphur application linearly increased the yield up to 50 kg ha-1 with bulb yield of 35.5 tonnes. Maximum pyruvic acid content in onion bulbs was noticed with sulphur application at 40 and 50 kg ha-1. However, application of sulphur did not affect number of scales and TSS content of onion bulb.
