Investigation was carried out from November, 2013 to march 2014, the purpose of this investigation is to evaluate AquaCrop model simulation of canopy cover, dry biomass and soil water balance in dry bean crop. The area of investigation belonging to UBPC Grito de Yara, belonging to Yara county of Granma province. The investigation area was a plot, with nine furrows with 0.8 m width and 100 m length. The plot was divided into 3 subplots with 33 m of length, central furrow of each subplot were utilized for measurement. Variety Delicias 360 was sown 20 december of 2013, with 0,5 m of plant spacing and 0,8 m of row spacing. Canopy cover (CF), dry biomass (BSA) and soil water content (CHS) evolution simulated by AquaCrop model were similar in tendency and absolute values to that observed. Considering as a criteria statistical indicator R² (0,81; 0,95; 0,99), RMSE (13,4; 0,45;7,3), NRMSE (19,3; 17,0; 7), EF(0,8; 0,94; 0,63) y d (0,95; 0,98; 0,92) for variable CF, BSA y CHS, it can be seen that the AquaCrop model can adequately simulate an observed variable
