The experiment was conducted aiming to evaluate the effects of fertilization management in the pregerminated system, on grain yield and nutrient loss through early drain discharge. The treatments were: T1- Control (without fertilization); T2- fertilization 20 days before sowing without incorporation; T3- fertilization 20 days before sowing with fertilizer incorporation; T4- fertilization 05 days before sowing without incorporation; T5- fertilization 05 days before sowing with fertilizer incorporation; T6- fertilizer application 10 days after sowing; T7- fertilizer application 25 days after sowing. Grain yield was not affected by the different fertilization management procedures. The fertilizer applied 05 days before sowing promoted the highest nutrients loss, especially potassium. However, recorded loss values were within the range allowed by current legislation.
