Abstract A field experiment was conducted at the Bidhan Chandra Krishi Viswavidyalaya, Jaguli, Nadia, West Bengal, during rainy season (kharif) 2019, to study the effect of different nutrient sources on growth, yield and economics of scented rice (Oryza sativa L.). Among 9 treatments, integrated nutrient management (FYM 4 t + N20P10K10 kg/ha) led to the maximum tiller production (345.4 /m2) at 56 days after transplanting (DAT), the highest leaf-area index (LAI) (2.90) and dry-matter production (596.2 g/m2) at 84 DAT. Chemical fertilizer-based nutrition (N40P20K20 kg/ha) resulted in the maximum plant height (125.0 cm) at harvesting and grain yield (2.57 t/ha), being at par with FYM 4 t + N20P10K10 kg/ha (2.53 t/ha). Plants in LCC-based N-fertilized plots had moderate grain yield (2.18 t/ha) and least lodging tendency (score 2.3). Chemical fertilizer-based nutrition could record the maximum yield (2.57 t/ha), net income ( 42,126/ha) and benefit: cost ratio (2.02); but integrated nutrient management (FYM 4 t + N20P10K10 kg/ha) might be an alternative option for sustainable cultivation (2.53 t/ha, 38,069.50/ha and 1.86) in lower Gangetic plains of West Bengal.
