A field experiment was conducted on loamy sand soil of Jobner (Rajasthan) to find out the
effect of phosphorus, sulphur and PSB on yield, oil content and nutrient uptake by mustard.
Application of 30 kg P20~ ha-I recorded significantly higher seed, stover and oil yield and total
uptake of N, P and S over control and PIS but the N, P and S contents in seed and N and P
contents in stover were significant over control only. The S content in stover was significantly
higher Po and PIS due to treatment P30. Application of 90 kg S ha- I being at par with S60 produced significantly higher seed, stover and oil yield and N, P and S contents in seed and stover and their total uptake over control and S30' Seed inoculation with PSB significantly enhanced seed, stover and oil yield and uptake of N, P and S over no inoculation.
