Short Summary

This study used the FAO-CROPWAT 8.0 model to determine the optimal irrigation requirements for wheat, maize, and rice in eastern Iraq's Amarah Governorate, highlighting the need for frequent irrigation during critical growth stages.

Objective

• Determine the perfect water requirements for crops and irrigation needs in the Amarah Governorate, Iraq

Study Configuration

• Spatial Scale: Regional scale (Amarah Governorate, eastern Iraq)
• Temporal Scale: Annual cycle with a focus on crop growth stages

Methodology and Data

• Models used: FAO-CROPWAT 8.0 model
• Data sources: Climate data from local weather stations, soil data from the Soil Information System of Iraq

Main Results

• Crops water requirements ranged from 222.1 to 1127.4 mm per decade for wheat, 982.7 to 957.2 mm per decade for maize, and 1469.3 to 1863.4 mm per decade for rice.
• Irrigation scheduling revealed that rice and maize require more frequent irrigation than wheat due to lower rainfall during planting periods.

Contributions

• This study provides valuable insights into the optimal irrigation requirements for major crops in eastern Iraq, contributing to water sustainability and reducing consumption.

Funding

• This research was funded by the Ministry of Water Resources, Iraq (Project Code: MWRI/2020/01)
