Description:	A study was conducted to verify the application of a simple approach for water potential evaluation on mango (Mangifera indica, L). Data irrigation condition, at Embrapa Semi-Árido, Petrolina-PE. Data were obtained with apressure chamber and correlated with psychometric chamber measurements. Chamber pressure was halted at each 0.1 MPa for sap sampling with filter paper for differentiation between the resin and water outf1ow. Resin exudation was distinguished by the appearance of dark dots on the paper. The results showed that there was no correlation between the methods when the values obtained at the moment of resin exudation were used. However, data obtained at the moment of water outf1ow were significantly correlated through the equation Y= 0.1678 + 1.151 (X) and R= 0.98 **. The results suggest that the using of the filter paper to detect the moment of water outf1ow, may help obtaining accurate pressure chamber water potential measurement on mangoes.
