A field experiment was conducted during wet seasons of 2008 and 2009 at Bidhan Chandra Krishi Viswavidyalaya, Nadia, West Bengal to find out suitable organic nutrient management practice in scented rice (cv. Gobindabhog) for higher productivity, net return, nutrient utilization and soil health. All six nutritional treatments comprising FYM, vermicompost and mustard cake either alone or in combination with others recorded higher values of growth parameters, grain and straw yield over unfertilized control. Application of sole mustard cake (50% recommended dose of nitrogen (RDN) as basal + 50% RDN at 21 DAT) recorded highest plant height at harvest (135.3 and 131.3 cm), number of tillers m⁻² at active tillering (304 and 299) and panicle initiation (384 and 369), and leaf area index (LAI) at flowering (4.88 and 4.70). Sole mustard cake in two splits (50% basal + 50% top dressing at 21 DAT) resulted in highest grain yield (2.68 t ha⁻¹) and N uptake (43.7 Kg ha⁻¹), which was at par with combined use of FYM (50% RDN as basal) and mustard cake (50% RDN at 21 DAT). Integrated use of FYM and mustard cake equivalent to 50 Kg N ha⁻¹ could be recommended as organic nutrient management for indigenous aromatic rice of West Bengal based on overall consideration of pooled grain yield (2.63 t ha⁻¹), residual soil nutritional status, net returns (19,261 ha⁻¹ and 19,071 ha⁻¹) and benefit: cost ratio (1:90 and 1.84).
