Abstract: The present investigation entitled “Effect of integrated nutrient management on growth, yield, quality and nutrient uptake of onion [Allium cepa (L.)] Varieties.” was carried out during two consecutive seasons of 2021-22 and 2022-23 the experiment was conducted at fields of university, Bhopal (M.P.). This experiments has been conducted in 12 treatments and two verities and their 24 combinations, with three replications. The experiment has formed under Factorial Randomized Design. In the experiment the 12 treatments of integrated nutrient management such as F₁-PM (2 t/ha), F₂-FYM (6 t/ha), F₃-VC (5 t/ha), F₄-50% RDF, F₅-50% RDF + PM, F₆-50% RDF + FYM, F₇-50% RDF + VC, F₈-75% RDF, F₉-75% RDF + PM, F₁₀-75% RDF + FYM, F₁₁-75% RDF + VC and F₁₂-100% RDF, Two varieties are used in the experiments such as V1 (Nasik Red) and V2 (Agrifound Dark Red). The observations to be recorded under the experiments are Morphological parameters like Plant height (cm) at 90 and 120 DAT, Length of leaf (cm) at 90 and 120 DAT, Number of leaves per plant at 90 and 120 DAT, Neck diameters of plant at 90 and 120 DAT. Yield-attributing parameters like Moisture Content %, Bulb weight (g) and Yield/plot (kg). The result revealed that the maximum plant height at 90 and 120 DAT, Length of leaf at 90 and 120 DAT, Number of leaves per plant at 90 and 120 DAT, Neck diameters of plant at 90 and 120 DAT, yield-attributing parameters like moisture content %, bulb weight and yield/plot was observed under variety V2 (Agrifound Dark Red) and in case of fertilizer application all the parameters was found under treatment F₁₂ [100% RDF (N120P80K80)], in case of combined application of variety and fertilizers treatment combination V₂F₁₂ [Agrifound Dark Red + 100% RDF (N120P80K80)] was observed better compare to other combinations, while the minimum was observed under the treatments control.
