CROPWAT 8.0 Software is used to Estimate Crop Water Requirements and Reference Evapotranspiration (Tomato Farming in the Mostaganem Region)

Understanding water requirements is crucial for managing irrigation water in the province of Mostaganem in order to better meet demand and integrate supply. We decided to utilize the Windows version of CROPWAT 8.0. We estimated evaporation and then irrigation water requirements for tomato crops after entering fundamental climatic data from 2010 to 2022. We obtained irrigation schedules and tables that appropriately depict the crop’s water requirements and reference evapotranspiration for tomatoes based on soil, climate and plant characteristics after entering the data into CROPWAT 8.0. Next, we contrasted the monthly outcomes with the identical plant’s annual results. This work is part of sustainable development and especially the rational use of irrigation water following the Cropwat model. The use of cropwat is essential to maintain the correct irrigation schedule, especially in terms of irrigation timing and period. The results obtained showed that the crop requirement is always lower than the irrigation requirement, so the results obtained either monthly or annually are adequate.
