This work aimed to compare the soybean yield when phosphorus and potassium manuring was anticipated or at sowing. The experiment was carried out under feld conditions in a dystrophic Red Latosol (Oxisol). A completely randomized block design with six treatments and four replicates was used. The treatments were: 1) no manuring; 2) P and K at sowing; 3) anticipated P and K; 4) anticipated P; 5) anticipated K; 6) half of P and K anticipated and the another half at sowing. Yield, weight of 1000 grains, number of grains per pods and number of pods per plant were evaluated at harvest. There was no difference between anticipated and sowing fertilization to soybean. Therefore, the best option to soil fertilization should be that with the lowest cost.
