Field experiments were conducted on sulphur-deficient or nearly deficient soils, to evaluate the comparative response to sulphur application in raya and wheat crops at three locations in different villages of Punjab. The raya seed yield increased significantly by 33 to 141% over control with the application of sulphur at different locations but the yield increase in wheat was not significant. Sulphur content in and uptake by plants increased with the application of sulphur-fertilizer to the soil. The oil content in raya increased with the application of sulphur. The contribution of underground water towards the supply of sulphur from 4 irrigation sources varied from 12 to 27 kg S ha⁻¹ at different locations. The benefit to cost ratio of application of sulphur to raya crop varied from 10.6: 1 to 23.7: 1 at different levels of sulphur application.
