The experiment was constructed with Sulphur (S) and Boron (B) with three doses of each, i.e., S₀: without Sulphur (control), S₂₀: 20kg S/ha, S₃₀: 30kg S/ha and B₀: without Boron (control), B₂: 2kg B/ha, B₃: 3kg B/ha to study the effect on Boro rice (cv. BRRI dhan-28). In case of Sulphur, the treatment S₂₀ obtained the maximum plant height (97.811cm), maximum tillers hill^-1 (26.184) at harvest, highest panicle length (24.98cm), maximum grains panicle^-1 (167.37), maximum 1000-grain weight (27.57 g), maximum grain yield (5.46t/ha) and straw yield (5.71t/ha), maximum biological yield (11.17t/ha) and HI (48.88%). Whereas, maximum filled grains panicle^-1 (147.37) and minimum unfilled grains panicle^-1 (17.89) were found in S₃₀. In case of Boron, the highest plant height (96.378 cm) was found in B₃. Highest number of total tiller hill^-1 (25.149), longest panicle (24.17 cm), highest number of total grains panicle^-1 (165.78), filled grains panicle^-1 (144.04) and minimum unfilled grains panicle^-1 (21.74), maximum 1000-grain weight (25.24 g), highest grain, straw and biological yield (4.84, 5.43 and 10.27t/ha, respectively) and highest HI (47.13%) were found in B₂.The treatment combination S₂₀B₂ performed the best response than other treatments. Plant height was highest (100.30 cm) in S₂₀B₃ treatment combination at harvest. However, the maximum tillers hill^-1 (28.78) at harvest, highest panicle length (26.94 cm), maximum grains       panicle^-1 (177.57), maximum filled grains  panicle^-1 (150.27) and minimum unfilled grains panicle^-1 (27.30), highest 1000-grain weight (29.75 g), highest grain, straw and biological yield (6.30, 5.91 and 12.21t/ha, respectively) and higher HI (51.60%) were found in S₂₀B₂ treatment combination.
