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, 2020. The experiment revealed that grain and straw yield was significantly enhanced on addition of zinc, organics and their combinations over control. The highest grain and straw yield was obtained with combined application of RDF + RDF + Zinc (Zn) @ 50 kg ha-1 + Rice straw compost (RSC) @ 14.5 t ha-1. The application of RDF + RDF + Zinc (Zn) @ 50 kg ha-1 + Rice straw compost (RSC) @ 14.5 t ha-1registered the highest tiller productivity, leaf area index, root dry weight and root length. Based on the study, it is concluded that the application of RDF + RDF + Zinc (Zn) @ 50 kg ha-1 + Rice straw compost (RSC) @ 14.5 t ha-1is needed to achieve the improve the yield of rice in the soil.
