Resumen:
This work was carried out on a low-fertility Red Yellow Podzolic soil containing 79%-
sand and 11%-clay in A horizon, at Itapetininga Forestry Experiment Station, at São Paulo State,
Brazil. The objective was to evaluate a “taungya” system of a Pinus elliottii Engelmann var. elliottii
forest which was interplanted with three rows of corn (Zea mays Linnaeus). The experimental
treatments where the crop was established were as follows: a) without agricultural input; b) with
dolomitic limestone; c) with NPK fertilizer and d) both limestone and fertilizer, all under a
randomized-blocks statistically designed with four replicates. The parameters of evaluation included
crop production and initial growing of Pinus elliottii Engelmann var. elliottii forest. There were found
not statistical significant differences among yields of the intercropped corn treatments probably to the
low amount of clay and organic matter in the Podzolic soil researched. As to the growing until one
year-and-a-half old Pinus forest, no differences were found among treatments, probably due to the low
activity of these soil as well.
