Sweet corn (Zea mays saccharata Sturt) is a staple crop with significant economic value in the market. The growth and production of sweet corn, in terms of both quantity and quality, often fluctuate. One method to enhance the growth and yield of sweet corn is the application of coconut husk liquid organic fertilizer and MKP fertilizer. This study aims to determine the response of sweet corn growth and yield to the application of coconut husk liquid organic fertilizer and MKP fertilizer. The research was conducted from March to May 2024 at the experimental garden of the Faculty of Agriculture and Fisheries, Muhammadiyah University of Purwokerto. The method used was a Randomized Block Design (RBD) consisting of two factors: Coconut Husk Liquid Organic Fertilizer (POC Sabut Kelapa), with levels S0 = 0 ml/l, S1 = 75 ml/l, and S2 = 150 ml/l; and MKP Fertilizer, with levels M0 = 0 kg/ha, M1 = 200 kg/ha, and M2 = 400 kg/ha. The resulting data will be analyzed using ANOVA followed by a 5% DMRT test. The results showed that the application of the interaction between coconut husk liquid organic fertilizer 75 ml/l and MKP fertilizer 400 kg/ha significantly affected the variables of plant height at 14 and 42 DAP, cob weight without husk, cob diameter with husk, cob diameter without husk, cob length, and the number of kernels.
