ABSTRACT Laxamana, Rafael A, October 2022. "Growth and Flowering Performance of Anthurium as Influenced by Different Sources of Foliar Fertilizer.", Bachelor of Science in Agriculture major in Crop Science. Pampanga State Agricultural University, PAC, Magalang. Pampanga. Adviser: CARRENC. JUIC0, PhD. The study was conducted in San Agustin, Magalang, Pampanga from October 2022 to February 2023 to determ ine the influence of different sources of foliar fertilizer. The experiment was laid-out using Randomized Complete Block Design (RCBD) with five treatments and replicated three times. The treatments were as follows: To- (Control) T- Oscmote 14-414-14 1-2 grams per plant (Checked treatment) T- Grow more 15-15-30 1-2 tablespoon of four liters of gallon of water, Ts= Nutribella 20-20-20 1-2 tablespoon of four liters of gallon of water and Ts- Crop giant 15-1 5-30 1-2 tablespoon of four liters of gallon of water. Results of the study revealed that Ti (Osmocote) significantly produced the most number of flowers, number of new leaves, and size of leaves among the different sources of foliar fertilizer used. In terms of ROI, Ti (Osmocote) obtained the highest with 87.72%. However, plant height, diameter of flowers and number of suckers did not differ significantly.
