The purpose of this research was to determine the effect of goat manure liquid organic fertilizer treatment on the growth and production of tomato plants and to find out the best dose of goat manure liquid organic fertilizer that affects the growth and production of tomato plants. This research was conducted in Iloheluma Village, Tilongkabila District, Bone Bolango Regency. This research was carried out for 3 months using a Randomized Black Design (RAK) method involving 4 treatments, which were repeated 3 times to produce 12 experimental bed units. Each experimental unit consisted of 10 plants, which were planted in beds to produce in beds to produce 48 plants. With a dose of P0 as a control, P1 with a dose of 10 ml/plant, P2 with a dose of 20 ml/plant, and P3 with a dose of 30 ml/plant. The statistical data analysis technique was the ANOVA F test. The results showed that the treatment using liquid organic fertilizer did not have a real effect on plant height, number of leaves, number of fruit per harvest, fruit weight per plant, fruit weight per plot, and fruit diameter. P2 treatment with a dose of 20 ml/plant was the best treatment among all treatments for increasing the growth and production of tomato plants.
