<![CDATA[Shallots (Allium cepa L.) are a highly important horticultural crop and are widely used as a cooking spice in Indonesia. Optimal treatment is essential to increase the growth and production of shallots, one way being fertilization. The aim of this study was to determine the effect of liquid organic fertilizer from tofu dregs and chicken manure, as well as the interaction between liquid organic fertilizer from tofu dregs and chicken manure on shallot growth. This study was conducted at the Berastagi Agricultural Technology Research and Assessment Installation (IP2TP) at an altitude of approximately 1,340 meters above sea level. The research period started from August to December 2023. This research used a Factorial Randomized Block Design consisting of 2 factors, namely the first factor of POC from Tofu Dregs (T) with 4 levels namely T0 = Control, T1 = POC from Tofu Dregs 150ml/L, T2 = POC from Tofu Dregs 300 ml/L, T3 = POC from Tofu Dregs 450ml/L, and the second factor of Chicken Manure (A) with 3 levels A0 = Control, A1 = Chicken Manure 0.6 kg/plot, A2 = Chicken Manure 1.2 kg/plot. The results of the study showed that the Application of Liquid Organic Fertilizer (POC) of Tofu Dregs (T) had no significant effect on plant height, number of leaves, number of shoots. With the best treatment being T3 (POC from Tofu Dregs 450 ml/L). Application of Chicken Manure (A) had no significant effect on plant height, number of leaves, number of shoots. The best treatment was A2 (1.2 kg of Chicken Manure/plot). The interaction between Tofu Dregs Organic Fertilizer (T) and Chicken Manure (A) had no significant effect on plant height, leaf number, and tiller number, all observed parameters. The best treatment was T1A2 (150 ml/L of Tofu Dregs Organic Fertilizer and 1.2 kg of Chicken Manure/plot). Keywords: shallots, tofu dregs organic fertilizer, chicken manure]]>
