The rate of water requirement, as well as the characteristics of strawberry growth in normal circumstances, was investigated. Hence, the irrigation interval was so adopted that no stress was applied to the plant. Table 2 contains the results of evapotranspiration measurements and the irrigation rate in a 15-day time interval as recommended by Lozano et al. (2016).
