This study aimed to evaluate the growth ofBauhinÚJfoif=ta seedlings submitted to phosphorus leveis. Elevenday- old seedlings were transplanted to small tubettes (110 crrr') with pinus bark and vermiculite substratum base. The experiment was conducted in an entirely randomized delineation, with six P treatrnents: TO-control (substratum without P addition), Tl-50, T2- 100, T3-150, T4-200 and T5-250 mg drn", with five replications and 20 seedlings per replication, Mter 60 days, the seedlings presented a 98.2% survival rate and good root formation. The height varied in function ofP leveis, with maximum production up to the P dose of 250 mg drn "; 60 days after the transplant, similar behavior for leaf area and dry matter production was observed. Furthermore, the P incorporation increased the phosphorus (P), potassiurn (K) and nitrogen (N) accumulation in vegetable tissues. Seedling growth was positively influenced by P leveIs, and the maximum growth occurred up to the P dose of 250 mg drn". In conclusion, this characteristic showed that the species requires high leveIs ofP during initial growth, under the tubette system.  aAdubação  aFósforo  aMuda  aPlanta Medicinal  aProdução  aBauchinia forficata  aEspécvie arbórea1 aSILVA, A.
