“…The EC technique was applied in two studies (Testi et al, 2004;Martínez-Cob and Faci, 2010), and was associated with SF measurements in Cammalleri et al (2013b) and López-Olivari et al (2016). Puppo et al (2019) used drainage lysimeters combined with soil water content measurements for estimating ET c act . The soil water balance model SIMDualK c was calibrated and validated using sap flow based sensors in the study by Paço et al (2019), which was the only study considering the direct calculation of the crop coefficient and derived the K c curve following the FAO56 approach.…”

“…The majority of the studies were carried out in the Mediterranean basin, which is the leading producing region for olives. Two of the selected studies were performed in south America countries, one in southern Uruguay characterized by a sub-humid climate (Puppo et al, 2019) while the other was performed in a location in Chile, characterized by a Mediterranean climate (López-Olivari et al, 2016).…”

The present study reviews the research on the FAO56 crop coefficients of fruit trees and vines performed over the past twenty years. The main objective was to update information and extend tabulated single (K c ) and basal (K cb ) standard crop coefficients. The selection and analysis of the literature for this review have been done to consider only studies that adhere to FAO56 method, computing the reference ET with the FAO Penman-Monteith ET o equation and field measuring crop ET with proved accuracy. The crops considered refer to vine fruit crops, berries and hops, temperate climate evergreen fruit trees, temperate climate deciduous fruit trees and, tropical and subtropical fruit crops. Papers satisfying the conditions expressed above, and that studied the crops under pristine or appropriate eustress conditions, were selected to provide for standard K c and K cb data. Preference was given to studies reporting on the fraction of ground cover (f c ), crop height (h), planting density, crop age and adopted training systems. The K c and K cb values obtained from the selected literature generally show coherence relative to the crop biophysical characteristics and reflect those characteristics, mainly f c , h and training systems. The ranges of reported K c and K cb values were grouped according to crop density, particularly f c and h, and were compared with FAO56 (Allen et al., 1998) previously tabulated K c and K cb values, as well as by Allen and Pereira (2009) and Jensen and Allen (2016), which lead to define update indicative standard K c and K cb values. These values are aimed for use in crop water requirement computations and modeling for irrigation planning and scheduling, thus also aimed at supporting improved water use and saving in orchards and vines.

“…Direct computation of K cb with the A&P approach often requires the numerical search of the empirical parameters relative to canopy transparency to solar radiation (M L ) and to the effects of stomatal adjustment (F r ), e.g., in applications to peach (Paço et al, 2012) and olive (Paço et al, 2019;Conceição et al, 2017;Puppo et al, 2019), including to non-irrigated, water stressed olive groves (Santos et al, 2012). Applications also include crops not previously considered such as Chinese tamarisk (Li et al, 2015).…”

The A&P approach, developed by Allen and Pereira (2009), estimates single and basal crop coefficients (K c and K cb ) from the observed fraction of ground cover (f c ) and crop height (h). The practical application of the A&P for several crops was reviewed and tested in a companion paper (Pereira et al., 2020). The current study further addresses the derivation of optimal values for A&P parameter values representing canopy transparency (M L ) and stomatal adjustment (F r ), and tests the resulting model performance. Values reported in literature of M L and F r were analysed. Optimal M L and F r values were derived by a numerical search that minimized the differences between K cb A&P with standard K cb for vegetable, field, and fruit crops as tabulated by Pereira et al. (2021aPereira et al. ( , 2021b and Rallo et al. (2021). Sources for f c were literature reviews supplemented by a remote sensing survey. Computed K cb and K c for mid-and end-season together with associated parameters values were tabulated. To improve the usability of the M L and F r parameters a cross validation was performed, which consisted of the linear regression between K cb computed by A&P and observed K cb relative to independent data sets obtained from field observations. Results show that both series of K cb match well, with regression coefficients very close to 1.0, coefficients of determination near 1.0, and root mean square errors (RMSE) of 0.06 for the annual crops and RMSE = 0.07 for the trees and vines. These errors represent less than 10% of most of the computed tabulated K cb. The tabulated F r and M L of this paper can be regarded as defaults to support A&P field practice when observations of f c and h are performed. Therefore, the A&P approach shows to be appropriate for use in irrigation scheduling and planning when f c and h are observed using ground and/or remote sensing, hence supporting irrigation water savings.
