Abstract: A field experiments were conducted during the rabi season of 2015-16 and 2016-17 at Main Garden, Department of Horticulture, Dr. PDKV, Akola, to study the effect of different levels of NPK on seed yield of onion Cv. Akola Safed. The treatments consisted of factorial combinations of three levels of each nitrogen (0, 100, 150 kg ha^-1), phosphorus (0, 50, 75 kg ha^-1) and potassium (0, 50, 75 kg ha^-1) laid out in factorial randomized block design with three replications. Results of the two years experiment revealed that, number of primary and secondary umbels per plant, number of seeds per primary and secondary umbel, seed weight per plant and seed yield per hectare were found to be maximum with an application of 150 Kg N ha^-1, 75 Kg P₂O₅ ha^-1 and 50 Kg K₂O ha^-1. However, an application of 150 Kg nitrogen (N₂), 75 Kg phosphorus (P₂) and 75 Kg potassium (K₂) per hectare produced maximum diameter of primary and secondary umbel.
