Abstract

This research aims to study soil’s physical, chemical, and hydro-physical properties, and then integrate them with climatic characteristics to determine the water consumption needed for wheat crops using CROPWAT-8 of FAO 2008. Daily climatic data from 2006 to 2013 of Abo simple station were used to calculate the ETo, ETc, and water consumption of wheat crops. The findings revealed that temperature, humidity, wind speed, and solar radiation all influence seasonal variations in ET. The results of calculating the water requirements for the wheat crop (Egypt 1) in the study area depended on the sowing date, as it gave the lowest water needs when planting in the first week of November 2022 (4230.0 m3/feddan/season). There was a gradual increase in water requirements as it changed. The highest water needs were reached 6086.51 m3/feddan/season when wheat planting in the first week of January 2023.
