At the same time, there is a significant worry over the need to increase the area devoted to wheat production to satisfy the growing demand in the local region. The significant obstacle is to raise the quantity of grain produced while retaining or reducing the amount of irrigation water used. In this context, research was carried out to investigate the wheat water productivity based on detecting the sensitivity of wheat production to water consumption by utilizing remotely sensed data at the El-Salhia agricultural project, which is situated in the eastern portion of the Nile delta. The remote sensing data have been used to estimate the actual evapotranspiration (ETa) from Nov. 1, 2019, to Apr. 30, 2020. The sequence of monthly ETa has been used as a crop water consumption signature to classify the crops in the study area. The crop water consumption signature depends on the crop phenological and thermal signatures simultaneously. Based on crop water consumption signature, wheat, sugar beet and potatoes are the common crops in the study area, which consumed 435, 639 and 280 mm, respectively. The accumulated ETa represented the wheat water consumption during the season, while the wheat yield was collected from 20 pivot irrigation systems. The yield varied from 5.4 tons/ha to 7.32 tons/ ha. The variation in measured yield reaches up to 25 %, although there is only a variety of wheat water consumption that reaches up to 10 %. The water productivity ranged from 1.32 to 1.66 kg/m3, with an average of 1.47 kg/m3. The yield response factor (Ky) is more sensitive to wheat yield than wheat water consumption.
