Resumo: The integrated crop-livestock-forest system can enhance the overall production, especially of soybeans, and economics of farming in regions characterized by warm climate. The aim of this study was to evaluate whether strip of trees in the integrated crop-livestock-forest systems (ICLF) change the horizontal distribution of the soybean yield and reduces the production by area four years after the establishment of eucalyptus, in the north region of Mato Grosso State, Brazil. The experiment was conducted at Sinop/MT, evaluating the following treatments: 1) crop with soybean during the main season and maize intercropped with Brachiaria brizantha during the second season and 2) Crop-livestock-forest system with triple rows (3.5 m x 3.0 m) of eucalyptus, spacing of 30 m and east-west orientation, annually cultivated with soybean crop (main season) and maize intercropped with B. brizantha (second season). The experimental design was in randomized blocks with four replicates. In the production systems with trees, evaluations were carried out in four equidistant transects, at 3, 6, 10 and 15 m from the rows on the northern and southern sides. Significant differences were verified in the agronomic characteristics of soybean, difference in productivity was verified comparing the exclusive and integrated systems. The tree component affect the soybean yield by area in the fourth year of the system implementation. The interference of eucalyptus reduced the soybean grain yield by 20.0% and the effect was stronger close to the tree rows.
