BR-3 variety of rice responded significantly to applications of sulphur either in the form of gypsum or as elemental S. The response was more prominent in the soil where the available S content was below the critical level (9.5 ppm). Gypsum appeared to have a more beneficial effect than elemental sulphur on all the growth parameters. An increase of Ca 8% in grain yield was obtained with an application of 30 kg/ha S as gypsum. Although sulphur contents in various parts of rice plant varied significantly with different rates of S application, the N and P contents remained unaffected. The maximum content of S was recorded in plants receiving S between 30 and 40 kg/ha. Grain S content was significantly affected by S addition from both the sources. The changes in yield parameters as well as nutrient elements were significantly affected by S application
