A field experiment in factorial randomized block design (FRBD) with 3 replication and 9 treatment combinations was conducted at the AICRP of Mustard, College of Agriculture, Nagpur (Maharashtra) during the Rabi season of 2023-24 at research farm. The treatments included three levels of nitrogen (50, 65, and 80 kg N ha-1) and three levels of sulphur (15, 30, and 45 kg S ha-1). The results showed that, different nitrogen and sulphur levels had substantial effects on growth parameters such as plant height at 50% flowering stage (cm), number of siliqua plant-1, weight of siliqua plant-1, number of days taken for 50% flowering, 1000 seed weight (g), Yield of seed, straw yield, biological yield and harvesting index. However, the highest seed production (1225.11 kg ha-1) was achieved with the application of 80 kg N ha-1, which was significantly superior to lower levels 50 kg N ha-1 and which is at par with 65 kg N ha-1. In comparison to sulphur levels, sulphur level 45 kg ha-1 produced the highest number of siliqua plant-1, weight of siliqua plant-1, 1000 grain weight (g) and maximum grain output (1201.56 kg ha-1) were recorded.
