The field experiment was conducted on “Effect of silicon and sulphur on yield and chemical composition on rice and its residual effect on wheat in loamy sand soil” during the kharif and rabi seasons for two years 2016-17 and 2017-18 at Regional Research Station farm, Anand Agricultural University, Anand (Gujarat). The experiment was laid out in Randomized Block Design with factorial concept, comprising twelve treatment combinations of four levels of silicon (0, 150, 300 and 450 kg Si ha-1) and three levels of sulphur (0, 20 and 40 kg S ha-1) with three replications. The maximum Si and S content in grain and straw was noticed due to combined application of 450 kg Si ha-1 and 40 kg S ha-1. Significantly higher phosphorus content in grain and straw was found under application of 450 kg Si ha-1.No significant change in P content in grain and straw were observed with varying levels of S application. Significantly highest Si and S uptake by rice grain and straw was observed under highest Si application (450 kg Si ha-1) with highest S level at 40 kg ha-1 over rest of the combinations. The maximum P uptake by rice grain and in rice straw was recorded due to application of 450 kg Si ha-1 during both the years as well as on pooled basis respectively. Addition of sulphur increased P uptake by grain and the maximum uptake was recorded at 40 kg S ha-1 during second year and pooled basis.
