Abstract


This study aimed to evaluate the effect of different levels of compost fertilizer on the productivity of three forage grass species: odot grass (Pennisetum purpureum cv. Mott), elephant grass (Pennisetum purpureum), and pakchong grass (Pennisetum purpureum cv. Purple). The experiment was conducted over a two-month period using a one-way Completely Randomized Design (CRD) with four treatments: no compost (P0), 30% compost (P1), 50% compost (P2), and 70% compost (P3). The observed parameters included number of leaves, number of tillers, plant height, and stem diameter. The results indicated that compost application generally had no significant effect on the number of leaves and tillers for all grass types, except for a significant difference in the number of tillers in pakchong grass. The application of 70% compost (P3) significantly affected the plant height and stem diameter of elephant grass, demonstrating its positive response to an organic-rich growing medium. Conversely, pakchong grass exhibited reduced growth under high compost treatments. These findings underscore the importance of adjusting the composition of planting media based on the specific physiological characteristics of each grass species.
