Abstract:
A field experiment in Factorial randomized block design (FRBD) with replication and 10 treatment combinations was conducted at the Crop Research Centre-II, ITM University, Gwalior (Madhya Pradesh) during the Rabi season of 2022-23 at the polyhouse research farm. The treatments included three levels of nitrogen (30, 60, and 90 kg N ha-¹) and three levels of sulfur (12, 15, and 18 kg S ha-¹) with one absolute control. The results showed that different nitrogen and sulfur levels had substantial effects on growth parameters such as plant population (m²), plant height (cm), number of primary and secondary branches plant-¹, leaf area index (LAI), and dry matter accumulation (g). and Increased nitrogen levels increased yield qualities such as Siliqua plant-¹, Siliqua plant length (cm), seeds Siliqua-¹,1000 seed weight (g), quality such as oil content, and oil yield was highest at 90 kg N ha-¹. However, the highest grain production (1882 kg ha-¹) was achieved with the application of 90 kg N ha-¹, which was Significantly superior to lower levels (0 and 30 kg N ha-¹) of nitrogen, with the exception of 60 kg N ha-¹. In comparison to other Sulphur levels, Sulphur level 18 kg ha-¹ produced the most plants (m²), the tallest plants possible, the most primary and secondary branches per plant, the highest leaf area index, and the dry matter accumulation (g). The number of Siliqua plants, seeds, and Siliqua length (cm), 1000 grain weight (g), and maximum grain output (1817 kg ha-¹) were also recorded.
