This study aimed to produce eucalyptus clusters panels ( Eucalyptus urophylla) and paricá (Schizolobium amazonicum) in association with broom ( Sida spp.). Tthe anatomical properties, chemical, basic density of paricá and eucalyptus wood, and stem broom were determined. For the chipboard production, some mixtures in 4 proportions (25, 50, 75 and 100%) of broom particles were used, in association with eucalyptus particles and paricá, and association of eucalyptus particles with paricá, being added to these two levels of adhesive based on urea formaldehyde (6% and 8%). The physical and mechanical tests were performed according to NBR/ABNT 14810-3 (2002). The experimental results showed that the adhesive content increasing in the chipboard production helped to improve some physical and mechanical properties. It is concluded that the broom particles increasing in panels had different effects, depending on the used species. The percentage increasing of broom particles to panels produced with eucalyptus did not affect the internal bond, pullout screw, and Janka hardness. The percentage increasing of broom particles to panels produced with paricá did not affect the resistance to Janka hardness and pullout screw. The percentage increasing of broom particles to panels produced with paricá did not affect the apparent density and water absorption, after twenty four hours of immersion. Moreover, the panels produced with broom particle absorbed more water and therefore the thickness swelling increased and so, they were not recommended for using in environments with high humidity. It was concluded that the genus Sida, in general, has potential for chipboard production.
