The present field experiment was conducted during the wet season of 2012 and 2013 to find out the optimum nutrient management practice for aromatic rice Gobindabhog in an alluvial soil. The experiment was laid out in split plot design with five organic matter levels (O1-Control or no organic manure, O2-FYM @ 2.5 t ha ⁻¹, O3-FYM @ 5 t ha⁻¹, O4-Mustard cake (MC) @ 0.5 t ha⁻¹, and O5-MC @ 1t ha⁻¹) in main plot and three inorganic fertilizer levels (IN1-N₂₀ P₁₀ K₁₀, IN2-N₃₀ P₁₅ K₁₅, IN3-N₄₀ P₂₀ K₂₀) in subplot. Among the treatment combinations, the highest total dry matter production and number of tillers per unit area, straw and grain yield and N, P and K uptake by rice were observed in treatment receiving mustard cake @ 1 t ha ⁻¹ along with inorganic fertilizer @ N₄₀ P₂₀ K₂₀. Considering the net return (Rs. 16, 057 and Rs.28, 767/ha) and benefit: cost ratio (1.53 and 1.92) in both the year, treatment receiving 2.5 t ha ⁻¹ FYM along with chemical fertilizer @ N₃₀P₁₅K₁₅ was the most profitable nutrient management practice.
