Available soil water is the most important factor that limits growth and yield crops under extensive conditions. The objective is quantify loss yields due to water stress ay Balcarce. Potential and actual yields were calculated from potential and actual evapotranspiration and water use efficiency for a 26-year period. Potential yields ranged from 9500 to 12300 kg/ha, while actual yields varied from 7000 to 11000 kg/ha. Losses yield about 15% had 0.5 of probability. The bigger loss (40%) had a frequency of 4%.
