A pot experiment was conducted to evaluate the effect of sulphur oxidizing bacteria (SOB) on soil nutrient availability, nutrient uptake and other growth parameters of Brassica napus Var. GSC-7. The experiment was laid down in different combination of recommended inorganic fertilizers, two doses of sulphur (75 & 100%), sulphur oxidizing bacterial cultures and consortium biofertilizer (CB). Results revealed that consortium biofertilizer work in cooperative nature with sulphur oxidizing bacteria in soil. Application of single SOB38 inoculant along with CB significantly enhanced the nitrogen and sulphur uptake of plant. However, SOB10 with CB and 100% sulphur resulted in enhanced uptake of phosphorus and potassium nutrients. Application of SOBC + CB with 100% sulphur dose significantly increased available nitrogen (243.02 kg/ha), phosphorus (15.77 kg/ha), potassium (121.88 kg/ha) and sulphur (14.773 ppm) content of soil. Significantly higher nutrient uptake of nitrogen, phosphorus, potassium and sulphur was also recorded in same treatment. Plant growth, root shoot biomass was significantly increased with application of SOBC + CB + sulphur @ 100% dose. Maximum plant height (86.04 cm), dry root weight (0.683 g) and shoot weight (5.435g) was recorded in treatment having SOBC + CB+ 100% sulphur. So, the integrated application of SOBC with CB was markedly effective in improving the soil nutrient status, plant nutrient uptake and growth of Brassica napus Var. GSC-7.
