A pot experiment was conducted in the pot culture yard of the Department of Soil Science and Agricultural Chemistry, Faculty of Agriculture, Annamalai University, during July-October, 2016. The experiment revealed that grain and straw yield was significantly enhanced on addition of silicon, organics and their combinations over control. The highest grain and straw yield was obtained with combined application of RDF + 100% (Si + RSC). The application of RDF + 100% (Si + RSC) registered the highest tiller count, leaf area index, root dry weight and root length. Based on the study, it is concluded that the application of RDF + 100% (Si @ 200 kg ha-1 + RSC @ 14.5 t ha-1) is needed to achieve the improve the yield of rice in the soil.
