Abstract

The present study aims to determine the crops coefficient of two locals varieties of durum wheat :“Boutaleb” and “Bousselam” during the 2019/2020 crop season. The experimental studies werecarried out on six lysimeter, under irrigated conditions at the site of the Technical Institute of Field Cultures in Setif (ITGC). Crops coefficient “Kc” was calculated using referenceevapotranspiration “ET0” and maximum evapotranspiration “ETM”. ET0 was calculated usingcropwat software and ETM by water balance using the lysimeter. The curves of the cropscoefficient obtained for the two varieties “Boutaleb” and “Bousselam” are similar that are given by the FAO, but the differences exist in the values. The water efficiency of "Bousselam" variety is 48.28 Kg ha-1mm-1 which is more efficient than "Boutaleb" variety
