Soy is one of the world´s most widely produced crops among comercial cultivated. It has great importance in the feeding of humans and animals. The average world production in the years 2016/2017 was around 113,92 million tons. In order to reach the maximum of its productivity, it is necessary to take in account its nutrition, that is, an adequate, quality and more viable fertilizer. In Brazil there are several forms of fertilization. In Paraná, fertilization is carried out in the furrow along with the seed, whereas in Mato Grosso, the same fertilization is done by haul after sowing. Thus, this work aims to compare what is the best form of fertilizer application in soybean (Glycine max), for the Paraná region. The experiment was realized in Mandaguaçu, Paraná State. The outline was carried out in randomized blocks, with 4 treatments with 5 repetitions, being the treatments N-P-K in the sowing furrow, N-P-K in haul, N-P-K 50% in the furrow and 50% in haul and the control without fertilization. The agronomic parameters evaluated were: height, numbers of pods, weight of a thousand grains, humidity and productivity. The results were placed under analysis of variance of the data (p<0.05) and the Scott Knott test was no significant difference at 5%. In this sense, the study pointed out that there is no difference between the treatments performed.
