The study was conducted February 2022 to March 9, 2023, to determine effects of levels of vermicompost on peanut intercropped in coffee plants. The study aimed to determine the best treatment using the following parameters: growth, yield performance, and Cost and Return Analysis (ROI). The different treatment in the study was: T1- Farmers Practice, T2- RR+700kg of vermicompost/ha, T3- RR+750kg of vermicompost/ha, T4- RR+800kg of vermicompost/ha. and layout in Randomized Complete Block Design (RCBD). Significant results were shown 30 days after planting (DAP) on the height of peanut plants. The number of peanut root nodules at 20, 40 and 60 DAP, T4- RR+800kg of vermicompost/ha obtained highest mean of 25.80 cm, 36.58 cm, and 53.65 cm respectively. While T4- RR+800kg of vermicompost/ha obtained highest number of leaves, and T1- Farmers Practice obtained lowest. The to weight of pods, developed pods, and number of seeds per pod shows that T4- RR+800kg of vermicompost/ha obtained the highest mean. T1- Farmers Practice obtained the lowest number of undeveloped pods with a mean of 10.15g. Moreover, T4- RR+800kg of vermicompost/ha remained the highest yield/ha with a mean of 1,543 kilograms. The application of T4- RR+800kg of vermicompost/ha obtained the highest ROI gaining 259.13%. The study revealed that NSIC Pn 09 applied with different levels of vermicompost as organic fertilizer influenced the plant height, root nodules, leaves, developed and undeveloped pods, seed number and pod weight. While, T4- RR+800kg of vermicompost/ha obtained highest plant height, root nodules, leaves, developed pods, seeds per pod, yield/ ha and ROI.
