In an experiment with 3 stand densities and 12 prune treatments there were analyzed the effects ofstand density, prune and interaction between them on the yield of a Pinus taeda L. plantation. The standvariables analyzed were diameter at breast height (DBH), stem volume, volume per hectare, height, basalarea, diameter over stubs (DMSM), Girard form coefficient (CFG), diameter of branch (DRBC) andbranches angle (ARBC) at crown base. In the treatments with high density there were observed highervolume per hectare, basal area, CFG and lower DBH, stem volume, DMSM, DRBC and ARBC. In thetreatments with lower prune height there were observed higher DBH, stem volume, volume per hectare, basalarea than the treatments with larger prune height. Lower DMSM was observed with final prune height of3,30 m and 4,40 m made at the age of 4 year. Higher DMSM were observed with final prune height of 5,5and 6,6 m made at the age of 5 year. No statiscaly significant effects were found of the prune treatments overDRBC, ARBC and CFG or interaction between stand density and prune height. The density and prune yieldeffects were independent from each other.
