Sulphur and varieties are yield limiting factors for rapeseed production in the sandy loam soil (Inceptisols) of the Madhya Pradesh, India. A field experiment was conducted to study the effect of Sulphur and varieties on growth, yield and quality of mustard at student instructional farm of department of Agronomy, Faculty of Agriculture, AKS University, Sherganj, Satna (M.P.) during winter season of 2020-21. The experiment consisted of randomize block design having factorial arrangement with three replications. In this experiment, 12 treatment combinations including four levels of Sulphur and treatments were S₀- 0 kg/ha, S₁- 50 kg/ha, S₂- 60 kg/ha and S₃- 70 kg/ha, while three mustard varieties were tested are V₁- Varuna, V₂- Shekhar and V₃- Pusa bold. Higher plant height and number of branches per plant at maximum crop growth stage of 90 DAS (162.19 cm and 24.03, respectively) was recorded in plots treated with Sulphur @ 70 kg/ha with mustard variety Varuna. Similarly, resulted in maximumnumber of siliquae per plant (425.99), number of seeds/siliquae (17.47), test weight (4.39 g), seed and Straw yield (18.56 and 59.04 q/ha, respectively)as well as oil content (39.80 %) recorded under same treatment combination of Sulphur @ 70 kg/ha with mustard variety Varuna. It was concluded from the results that application of Sulphur @ 70 kg/ha with mustard variety Varunaimproved yield and yield components of mustard.
