Abstract: Field experiment was conducted at Agricultural College and Research Institute, TNAU, Madurai, to study the feasibility of yield and biochemical properties in traditional red rice landraces cultivation with different nutrient management viz., FYM 12.5 t ha-1 + RDF 50:25:25 NPK kg ha-1 + Azophos 2 kg ha-1 and FYM 12.5 t ha-1+ Azophos 2 kg ha-1. Red rice land races from Southern Districts of Tamil Nadu viz., V1 Kallurundaikar, V2 White Chithiraikar, V3 Sivappu Chithiraikar, V4 Mattaikar, V5 Kuruvaikalangiyam, V6 Kuliyadichan, V7 Norungan, V8 Nootripattu, V9 Chandikar, V10 Kattanur and V11 TKM 9 improved TNAU red rice variety taken as a check. Among the Variety (V9) recorded significantly highest grain and straw yield (4031 and 9350 kg ha-1), and higher biochemical properties viz., carbohydrates, protein, fiber, Zinc content was found in variety TKM 9 (V11) with application of organic source, FYM + Azophos (F2 V11). Higher Iron and fat content was recorded in combination of Chandikar (V9) and Nootripathu (V8) with organic nutrient sources of FYM + Azophos (F2 V9 & V8) respectively.
