Conteúdo: 	The evapotranspiration of the mango crop was estimated by the soil water balance method in a drip irrigated mango orchard implanted in 1998. The experiment was carried out at Federal Agricultural Technical School of Guanambi located in the Irrigated Perimeter of Ceraima, Guanambi county, Bahia State. The works lasted 50 days (Period of budding to initial fruit growth). Soil water content was monitored by a data acquisition system with TDR, that made readings at 15- minute intervals in many locations of a grid in a vertical plane around the plant. Data were collected for plants irrigated with amounts of water equivalents to 100 % and 60 % of ETc (crop evapotranpiration), with and without covering the shaded area around plants. ETc and deep percolation varied according to distance from plant. There was a difference about 30% between ETc obtained with covered soil and bare soil for plants irrigated with 40% of reduction of water needs (ETc). The difference was about 10% in case of plants irrigated with no reduction of water needs.
