A field experiment was conducted to study the effect of sulphur nutrition on growth and sulphur content in rice and mustard grown in sequence. The experiment was laid out in split plot design with four sulphur levels (0, 15, 30 and 45 kg/ ha) applied to rice as main plot treatments during rainy season and each plot was further divided into three subplots (0, 20 and 40 kg S/ ha) applied to mustard during winter season. Increasing sulphur levels in rice significantly improved leaf area index, tiller number, dry matter production, harvest index and sulphur content in rice up to 45 kg S/ ha and its residual effect on leaf area index, dry matter production, harvest index and sulphur content in mustard was also significant up to 45 kg S/ha. Sulphur application to mustard improved leaf area index, dry matter production, harvest index and sulphur content in mustard upto 40 kg/ ha and its residual effect on succeeding rice crop was also significant upto 40 kg S/ ha with respect to leaf area index, dry matter production, harvest index and sulphur content in rice grain and straw.
