Background: Increased demand for quality based rice and rice products motivate the farmers for producing the traditional rice varieties. To meet the demand, rice production need to be substantially increased with suitable nutrient management practices. Methods: The field experiment was conducted during Early kar (2023) and Late samba (2023-24) seasons at Wetland farm, Department of Agronomy, TNAU, Coimbatorre. The experimental design consisted of twelve treatments laid out in Randomized Block Design with three replications. Based on N equivalent basis, required quantity of inorganic fertilizer, farmyard manure, vermicompost and poultry manure were applied to rice. Result: The results revealed that application of 50% RDN through inorganic fertilizer + 50% RDN through vermicompost + Foliar spray of 0.5% ZnSO4 + 1% FeSO4 at Tillering, PI and Flowering stage (T11) registered higher physiology, yield parameters and grain yield.
