One of the staple foods that is really needed by the community is horticultural agricultural products, where shallots (Allium ascalonicum L.) have a superior position in this commodity. Shallots play an important role in various dishes, giving them significant economic value. Shallots, the main choice for human consumption after chilies, are used as a spice in various dishes. The aimed of this research is to examine the application of compound NPK fertilizer doses to the growth and yield of shallot plants of the Bima Brebes variety. The method used in this research was an experiment according to the rules of a Randomized Block Design consisting of 4 treatments, each treatment was repeated 3 times and obtained 12 treatment units with 3 shallots in each treatment, so that a total of 36 shallots were obtained. The results of observations of the fresh weight of shallot plant bulbs showed that there was no real effect. When observing the fresh weight of the tubers, the heaviest tuber was P3 (2.1 g NPK/polybag), namely 58.5 g. The element that plays an important role in the formation of tubers is phosphorus. The results of research on the dry weight of shallot bulbs showed that there was no significant effect. The largest dry weight of bulbs was that of P3, namely 47.6 g. The air-dry weight of the bulbs indicates that the fresh weight of the bulbs that have been air-dried, the amount of water content contained therein, has decreased in the shallot plant bulbs. The research conclusion was that the application of various doses of compound NPK fertilizer did not have a real effect. It is best that when cultivating shallots there is no need to add compound NPK fertilizer because applying chicken manure is sufficient.
