Abstract:
This research was conducted based on maize crop experiment in Agricultural Scientific Research Center of Lattakia among the years 2018-2019. In order to domenstrate the importance of using MABIA as an integrated model in irrigation through basic inputs inclauding climatic factors for calculating potential evapotranspiration ET0 (temperature, relative humidity, solar radiation and wind speed), soil mechanical analysis and soil moisture indicators (field capacity, permanent wilting point, saturation) and crop (variety. , planting and harvesting date), the irrigation system (surface, sprinkler, drip) and irrigation criteria (TAW, RAW….). Scenarios of studying crop water requirement and water productivity were suggested including: changing soil texture, deficit irrigation and the combination the two previous scenarios, based on logical assumptions leads to important results and recommendations regard to crop water requirement under climate change impacts. Maize water requirement was 7740 m3 in 2018 and 7670 m3 in 2019. soil mechanical analysis and accurate determination of soil texture have important effects on irrigation requirement and crop yield.
Key words: maize, water requirement, model, MABIA, scenario.
