  abstract = {{C}urrently, the {A}qua{C}rop model has been widely tested for many fruit/grain crops; root and tuber crops; leafy vegetables, or forage crops, but is restricted to annual herbaceous species, while deciduous crops have received less if no attention. {I}n this context, this study aims to test for the first time the ability of the {A}qua{C}rop model to simulate canopy cover ({CC}), actual evapotranspiration ({ET}a), total soil water content ({TWC}), biomass ({B}) and fruit yield ({FY}) of table grapes vineyards ({V}itis vinifera {L}., cvs. {P}erlette and {S}uperior) at the {C}osta de {H}ermosillo, {S}onora in {N}orthwest {M}exico. {O}bserved weather and soil physical parameters, with measured crop parameters from an experiment conducted during 2005 were used to develop climate, soil and crop input files for {A}qua{C}rop and for calibrating the model. {W}hile collected data during the 2006 growing season were used to validate the model. {T}he model adequately simulated {CC}, {ET}a and {TWC} during 2005 and 2006. {T}he {R}oot {M}ean {S}quare {E}rror ({RMSE}) between observed and measured {CC}, {ET}a and {TWC} were 5.18%, 0.46 mm/day and 10.11 mm during 2005, and 8.82%, 0.84 mm/day and 9.1 mm during 2006, respectively. {T}he good accuracy of simulations of {CC}, {ET}a and {TWC} by the model have been confirmed by additional statistical parameters like the coefficient of determination ({R}-2), {T}he {M}ean {B}ias {E}rror ({MBE}), the {W}illmott's index of agreement (d) and the {N}ash-{S}utcliffe {E}fficiency ({NSE}). {F}or the {B} and {FY} simulations, the results showed that the model correctly reproduced the {B} and {FY} with {NRMSE} value of 8.8%. {T}he estimated average value of {FY} (14.56 t/ha) for both seasons are in the range of the potential yield (14-18 t/ha) of table grapes in the irrigated {C}osta de {H}ermosillo in northwest {M}exico. {A}fter the validation of the {A}qua{C}rop model, it was used to evaluate the irrigation scheduling by the farmer as well as to assess the water productivity computed as the ratio of crop production to crop water use. {T}he results showed that, the recommended irrigation by the model was about 547 mm and 509 mm, which it is about half of that applied by the farmer (1006 mm and 929 mm) during 2005 and 2006, respectively. {T}his large difference, which represents approximately 54% and 57% of the irrigation supply, is lost through deep percolation and could be saved without vegetation suffering from water stress while maintaining the same yield. {T}he high loss of water by percolation affects significantly the water productivity ({WP}), which decreases from 3.22 to 1.74 kg/m(3) if we consider the transpiration ({WPT}r), and the sum of {ET}a and {P}ercolation ({WPET}a+{P}r) for {WP} computations, respectively. {C}onsequently, the {A}qua{C}rop model can be used as an operational tool by decision makers and growers to improve irrigation management. {T}his is of crucial importance in arid and semi-arid regions where water is becoming increasingly scarce.},
