Shallots are one of the most important horticultural commodities in Indonesia, with high market demand. This study aims to assess the impact of the use of NPK and ZK (potassium sulfate) fertilizers on total nitrogen content in the soil, nitrogen uptake, and yield of shallots on Inceptisol soil type. The experiment was conducted at the Soil Chemistry and Plant Nutrition Experimental Field, Faculty of Agriculture, Universitas Padjadjaran, from September to December 2023. The research design used in the experiment was a Randomized Group Design (RAK) with 6 treatments consisting of 1 control treatment, 1 NPK (16-16-16) treatment, and 4 treatments of a combination of NPK + ZK fertilizer doses. The results showed that the NPK + ZK fertilizer treatment influenced the N-total, N uptake, and yield of shallot bulbs. The application of ¾ NPK + ½ ZK fertilizer gives the best results of N-total, N uptake, and yield of shallot bulbs.
