Abstract:
This study aims to determine the effect of inorganic fertilizer, organic fertilizer, and the combination of both on the growth of king grass (Pennisetum purpurephoides). The research method was a completely random design with 4 treatments and 5 replications. The research treatments consisted of A (without fertilizer), B (100% inorganic fertilizer), C (100% organic fertilizer), and D (50% inorganic and 50% organic fertilizer). The result of the study shows that inorganic, organic, and its fertilizer combination treatment has a non-significant effect on the height of the plant, the length and width of the leaf, and the length of its segments, while inorganic and organic fertilizer treatment has a significant effect on the stem diameter. The conclusion is that the use of 100 % organic fertilizer has better results for the vegetative growth of king grass (Pennisetum purpurephoides) compared to the use of inorganic fertilizer and its combination.
