The field experiment on effect of sources and levels of sulphur on soil nutrient availability, yield, quality and uptake of nutrients of bellary onion. Total treatments were 14 with three replications in randomized block design. The treatment consist of three sulphur levels @ 30, 45, and 60 kg ha-1 in presence of Thiobacillus thiooxidens, sources of sulphur as elemental sulphur along with recommended dose of fertilizer (110:40:60 kg ha-1 N, P2O5 & K2O + 15 t ha-1 FYM). The application of RDF + S @ 60 kg ha-1 as elemental sulphur + Thiobacillus thiooxidens - nutripellet pack and was significant for phenol (4.70 mg 100 g-1), flavonoids (327 µ mole g-1), ascorbic acid (4.69 mg 100 g-1), pyruvic acid (2.64 µ mole g-1) and TSS (12.930 brix). It was statistically on par with treatment RDF + S@ 45 kg ha-1 as elemental sulphur + Thiobacillus thiooxidens - nutripellet pack and RDF + S@ 60 kg ha-1 as elemental sulphur + Thiobacillus thiooxidens – soil application for phenol (4.69 and 4.67 mg 100 g-1), flavonoids (319 and 317 µ mole g-1), ascorbic acid (4.49 and 4.42 mg 100 g-1), pyruvic acid (2.46 and 2.41 µ mole g-1) and TSS (12.74 and 12.660 brix).
