Agricultural Water Management, 248,1066970378-377410.1016/j.agwat.2020.106697http://hdl.handle.net/10566/6104This study reviews the abundant research on FAO56 crop coefficients, published following introduction ofthe FAO56 paper in 1998. The primary goal was to evaluate, update, and consolidate the mid-season andend-season single (Kc) and basal (Kcb) crop coefficients, tabulated for many field crops in FAO56. The reviewfound that the prevalent approach for estimating crop evapotranspiration (ETc) is the FAO56Kc-EToapproach,i.e., the product of theKcand reference evapotranspiration (ETo).enTransferability of standardKcSugar cropsCerealsRiceFiber and oil cropsArticle
