Online published on 2 August, 2023. Abstract The emergence of new rice varieties, including HYV, hybrids and genetically modified rice, which are being developed as a result of corporate-centered technology, is putting traditional rice varieties in India and throughout Asia in danger of extinction. In order to better understand how artificial and organic inputs affect traditional rice production and growth, this study was carried out. A field study was conducted in Pazhankovil village, Thiruvannamalai district of Tamil Nadu, India in June 2021. This experiment used a randomized block (RBD) design with 11 treatments viz., T1 - Control, T2 - 100% RDF, T3 - 50% RDF + FYM @ 12.5 t/ha, T4 - 50% RDF + VC @ 2.5 t/ha, T5 - 50% RDF + Humic granules @ 25 kg/ha, T6 - 50 % RDF + FYM @ 12.5 t/ha+ NPK Consortia, T7 - 50% RDF + VC @ 2.5 t/ ha + NPK consortia, T8 - 50% RDF + Humic granules @ 25 kg/ha + NPK consortia, T9 - 50% RDF + FYM @ 12.5 t/ha + NPK consortia + Seaweed liquid @ 2% (FS two times), T10 - 50% RDF + VC @ 2.5 t/ha + NPK consortia + Seaweed liquid @ 2% (FS two times) and T11 - 50 % RDF + Humic granules @ 25 kg/ha + NPK consortia + Seaweed liquid @ 2% (FS two times) and were replicated thrice. Treatments consist of various organic solids and liquids that have been given in combination with 50% RDF. Results of the experiment revealed that among the different treatments tried, T10 treatment performed better compared to other treatments and use of 50% RDF with NPK consortia and FYM 12.5 t/ha (T6) found to be at par with application of 100% RDF (T2).
