A field experiment was conducted during the kharif seasons of 2021-22 and 2022-23 to assess the impact of integrated nitrogen management on the growth, yield, and quality of turmeric Cv. PDKV Waigaon. The study evaluated organic and inorganic nitrogen sources, including vermicompost, neem cake, and urea, along with their application timings. Results revealed that the application of 90% RDN through neem cake + 10% RDN (N₂). It was at par in the treatment (N₁). Growth parameters like plant height 90 DAP, number of leaves 90 DAP, leaf area 90 DAP and yield characters i.e. number of mother rhizomes per plant, number of primary rhizomes per plant were maximized when this nitrogen management strategy was paired with application timings at 30, 60, 90, and 120 days after planting (D₁). While, the maximum number of secondary rhizomes per plant in turmeric was produced when, nitrogen was applied with four equal split at interval of 40, 70, 100 and 130 DAP (D₂). Thus, integrated nitrogen management with neem cake and strategic application timing can significantly enhance growth and yield contributing characters in turmeric.
