Conteúdo:	The evapotranspiration of the mango crop was estimated by the soil water balance method in a ten-year age microsprinkler irrigated mango orchard. The experiment was carried out at Federal Agricultural Technical School of Guanambi located in the Irrigated Perimeter of Ceraima, Guanambi county, Bahia State. The work 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 CWN (calculated water need), with and without covering the shaded area around plants. ETc and deep percolation varied according to distance from plant. The difference between average ETc calculated for covered and bare soil was larger for water application equivalent to 100% of CWN. ETc values varied with distance from plant. The difference between average ETc calculated for covered and bare soil was larger for water application equivalent to 100% of CWN. Deep percolation, total infiltrated water and storage water were larger under covered soil surface in shaded area around the plant than for bare soil under same conditions.
