The objective of this work was to evaluate the growth of guanandi (Calophyllum brasiliense Cambess.) in floodplain, as homogeneous planting (control) and as two agroforestry systems - AFS (simple and biodiverse). Guanandi was planted in the Paraíba Valley, State of São Paulo in 2007. From 2011 to 2014, guanandi growth was evaluated in a randomized block design experiment with eight replications. The AFS consisted of planting annual crops between guanandi lines. The biodiverse AFS was formed with 16 tree species, banana shrubs (Musa sp.) and juçara palm (Euterpe edulis Mart.). Guanandi presented morphological similarity in homogeneous planting and agroforestry systems and reached, on average, 5.40 m of total height at seven years of age. The relative growth rate was similar in the three treatments with higher values attributed to the canopy radius (2.59%) and the circumference at 1.30 m above ground level (1.86%). Agroforestry systems are promising to combine the benefits of income generation and ecological restoration in planting guanandi in floodplain.
