The field experiment was conducted at farm of Divyayan Krishi Vigyan Kendra, Ramakrishna Mission Ashrama, Ranchi, Jharkhand, India during kharif season of 2021 following the three times replicated randomized block design with 7 organic N sources (control, 100% FYM, 100% vermicompost (VC), 100% Karanj cake (KC), 50% FYM +50% VC, 50% VC +50% KC, 50% FYM +50% KC) to study the response of transplanted aromatic rice to various organic N sources. The results expressed that N applied through manures ensured higher plant response over control and specifically, that through 50% VC +50% KC recorded the maximum plant height, tillers/m2 and leaves/plant. Further, this combined application of VC and KC also recorded maximum productive tillers/m2 (199.3), panicle length (24.1 cm), filled grains/panicle (172.8), test weight (22.9 g), grain yield (7.37 t/ha), straw yield (9.08 t/ha) and harvest index (44.8%) resulting in higher gross return (₹4,83,590/ha), net return (₹3,37,079/ha) and B:C (3.30). 100% N applied through KC remained as the second-best alternative in ensuring high growth, yield and profitability in aromatic rice.
