This work was carried out with the objective of investigating the effect of thinning eucalyptus at seven years of implantation on the components of production and productivity of soybean and maize crops, cultivated in the renewal of pasture in an agrosilvipastoral system. The experimental design used was a randomized block, with four replications, using as treatments three sampling positions of the components of production and grain productivity of soybean and maize crops in relation to the

The different sampling positions in relation to the planting line, under the two thinning of the eucalyptus, provided differences in relation to the mass of one hundred grains and grain productivity of the soybean crop and in relation to the height of plants, number of ears and mass of one hundred grains of maize crop. The standard treatment provided greater plant height in the soybean crop and greater insertion height of the first ear and higher grain productivity in the maize crop, and the sampling position at 2 m from the eucalyptus planting line under 0% thinning provided a lower mass of one hundred grains for soybean and maize crops and a lower number of ears ha -1 for the maize crop.
