Abstract: Field experiment was conducted at Agricultural College and Research Institute, Madurai, Tamil Nadu, to study the feasibility of yield enhancement for traditional red rice cultivation with different nutrient sources viz.,FYM 12.5 t ha-1+ Azophos 2 kg ha-1 and FYM 12.5 t ha-1 + RDF 50:25:25 NPK kg 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 this land races, Chandikar had significantincrease the growth and yield parameters by application of 12.5 t ha-1+ 50:25:25 kg NPK ha-1+ Azophos 2 kg ha-1.Rice variety Chandikar (V9) recorded significantly higher number of productive tillers m-2 (424), filled grains per panicle (125) and lowest sterility percentage (3.35 per cent). Among the combinationsF1 V9 registered higher grain yield of 4100 kg ha-1. When compared to check chandikar had 18.25 per cent yield increase and 3.25 per cent over Organic nutrient management.
