Description: Results of an energy balance based on the Bowen ratio method are presented. Two field experiments were carriedout in 1998 and 1999, with a mango orchard in Petrolina, PE. The mango trees were irrigated by a drip irrigationsystem. A micrometeorology tower was set up for installation of the instruments used for the energy balance,which are: net radiation, two psychrometers and two anemometers installed in two levels above the canopy of theculture, and more two radiometers (global solar radiation and the radiation reflected by the culture). Two plates formeasuring the soil heat flux in a depth of 5 cm were installed. The analog signals of all instruments were scannedonce every five seconds and averaged every 10 minutes using a micrologger. It was verified that didn't happengreat differences among the components of the energy balance in relation to the two experiments. In general, thelatent heat flux was of the order of 80% of Rn, while H and G represented around 15% and 5% of Rn, respectively.Such relationships were analyzed in different phenological phases, as well as the seasonal behavior of the energybalance components
