e2“Using 100% ETc under drip system resulted in very low water stress index ( WSI = 0.008), whereas using 100% ETc sprinkler system resulted in WSI = 0.1, which proved that application of 100% ETc enough to ensure high yield”

Other claims from this paper (6)
- Method / resource Calibrated CropSyst predicted wheat grain and biological yield with a high degree of accuracy.
- Observation Under drip irrigation, 100% ETc gave a very low water stress index (WSI = 0.008).
- Observation Under sprinkler irrigation, 100% ETc gave a water stress index of 0.1.
- Intervention effect Simulated application of 90% ETc reduced wheat yield losses under both irrigation systems.
- Intervention effect Simulated application of 90% ETc increased land and water productivity of wheat.
- Recommendation Applying irrigation water to wheat equal to 90% ETc is recommended to save water and increase water productivity.
