Abstract: The present study was conducted at ICAR-Central Potato Research Institute- RS, research farm Gwalior during winter (Rabi) season of 2022-2023. The experiment was laid out using Randomized Design with treatments T₁: Control, T₂: Inorganic practices (standard technology), T₃: NADEP compost @ 25 t/ha + Azotobacter @ 1 L/ha + PSB @ 1 L/ha, T₄: T₃+ FYM @ 25 t/ha, T₅: T₃+Vermicompost @ 7.5 t/ha, T₆: T₃+ neem cake @ 5 t/ha + foliar spray of copper oxychloride @ 3 g/L (for management of foliar diseases), T₇: Integrated practice [90% RDF through inorganic sources {urea, SSP, MOP}, 10% RDF through organic sources i.e., FYM @ 25 t/ha. The findings of results reveals that NPK content of haulm (1.77%, 0.47% and 1.86% respectively) and tuber (1.226%, 0.235% and 1.925% respectively) NPK uptake of haulm (43.108, 9.620 and 13.893 kg/ha), NPK uptake of PK (16.47 and 139.49 kg/ha respectively), N2 use efficiency (32%) and available N2 (187.778 kg/ha) in soil reported higher in treatment T₇. Higher N2 uptake by tuber (95.715 kg/ha), higher soil pH (7.053) found higher in treatment T₅. Higher EC (0.333 dSm^-1) and available K2O (442 kg/ha) of soil found in treatment T₃. Higher organic carbon (0.49%) and higher available P2O5 (21.045 kg/ha) of soil found in treatment T₄.
