The purpose of the research was to know the effect of C / N balance of bioslurry fertilizer (biogas sludge) and fertilizer dose on the growth of leek (Allium fistulosum). The design used was a complete randomized design of factorial pattern. The first factor of the C and N balances are 18, 20, 30 and 40. The second factor is the composting dose of 10 tons / hectare, 20 tons / hectare and 30 tons / hectare. Each treatment was repeated three times. The observed variables were the increase in length, width and number of strands. The data obtained were analyzed variance (ANOVA). The result of ststistic analysis shows that there is C / N influence on the number of strands; there was a dose effect on the length and width of leek but no interaction between C / N and the dose of fertilization. The best onion growth occurs at a dose of 10 tons / hectare as it leads to an increase in length, the highest width which is an important indicator of onion measurements.
