Abstract: An experiment was conducted under field conditions during kharif season of 2018 at the research farm of the ICAR-Indian Institute of Rice Research (IIRR), Hyderabad, Telangana state to know the effect of enriched nitrogen sources at different levels on yield attributes and yield of transplanted rice. Yield attributes like number of panicles (324 m^-2), total number of grains panicle^-1 (116), number of filled grains panicle^-1 (105) and panicle length (23.7 cm) were found to be highest with the application of 100% RDN through neem coated urea (T₇). Highest grain yield (6694 kg ha^-1) and straw yield (7812 kg ha^-1) was recorded with the application of 100% RDN through neem coated urea (T₇). This was found to be on par with 100% RDN through neem coated urea + nitrification inhibitor (T₁₀). Lowest grain yield (3120 kg ha^-1) and straw yield (4009 kg ha^-1) was recorded with (T₁) Control (0:60:40 kg N:P:K ha^-1).
