This research was conducted at Operational Greenhouse, Balai Benih Pertanian Kota Semarang Gunung Pati, Semarang. The research was conducted by 3x3 factorial experiments with 3 replications. The first factor was 6, 12, 18 days of incubation period and the second factor was 120, 240, 360 ml/plant dosage of LOF. The observed parameters were fruit N uptake, plant height, fruit diameter and fruit fresh weight. Results of study showed that both treatments had no significant effect on fruit diameter and fruit fresh weight caused by lack of P in LOF so that the overall fruit production was not optimum. Interaction between both treatments showed significant effect on fruit N uptake when on short incubation period, the dosage used was higher and vice versa. Six days of incubation with 240 ml/plant dosage gave the highest efficiency on improving fruit N uptake. Incubation period has no significant effect but the dosage of 360 ml/plant significantly gave optimum effect on plant height in comparison with dosage of 120 and 240 ml/plant. This research can be concluded that LOF with 6 days of incubation with dosage used between 240-360 ml/plant was efficient to improve growth of cherry tomato plant and addition of fertilizer was needed to improve production of cherry tomato.
