Sulfur plays an important role in the growth and yield of rapeseed plants. A field experiment was conducted in a randomized complete block design with seven levels of sulfur (60 kg/ha, 50 kg/ha, 40 kg/ha, 30 kg/ha, 20 kg/ha, 10 kg/ha, and 0 kg/ha in three replicates) to evaluate the effect of different doses of sulfur on the growth and yield of rapeseed (Brassica campestris var. Lumle Tori) in Khairahani, Chitwan. Plant height, number of branches per plant, number of pods per plant, pod length, grain per pod, pod weight, fresh weight, dry weight, stover weight, harvest index, and grain yield were recorded. Significant differences were observed in plant height, yield-related traits, and grain yield. The results showed significant differences between the growth and yield-related traits of the different treatments. Plant height and number of branches increased with increasing sulfur dose, reaching a maximum of 60 kg/ha. The maximum number of pods per plant was observed at 20 kg/ha, and the maximum pod length and grain per pod were observed at 60 kg/ha. Grain yield and harvest index were maximum at 20 kg/ha. The results showed that the maximum grain yield could be obtained by applying 20 kg/ha of sulfur. These findings provide valuable guidance for optimizing agricultural practices to meet the increasing global demand for oilseeds.
