| Abstract | ||||
| A field experiment was conducted during the growing season in 2023 to study the impact of climate changes (temperature, wind speed and relative humidity) on the performance of the center pivot and fixed irrigation systems (evaporation losses, Coefficient uniformity (CU), distribution uniformity (DU), water use efficiency and the production yield of peanut) in an open field at sandy soil in Wadi EL-Natroun region - El-Bhera Governorate, Egypt. The higher evaporation losses obtained in July (T= 27Cº, R.H =94% W.S =12.20 km/h) were 20.10% and 33.72% with the center pivot and fixed irrigation systems, respectively. The evaporation losses obtained in October were 8.7% and 10.42% with the center pivot and fixed irrigation systems, respectively (T= 27.70Cº, R.H= 78% W. S=14.40 km/h). The higher distribution uniformity was obtained in October of 80% and 77.8% (T= 28.80 Cº, R.H =78% W.S =15.10 km/h) with the center pivot and fixed irrigation systems respectively. The higher coefficient uniformity was obtained in October (T=27.7 Cº, R.H=78 % and W.S =14.4 km/h.) of 87% and 85% for the center pivot and fixed irrigation systems respectively. Production yield increased by 22.46% for center pivot irrigation system compared with the fixed irrigation system. Water use efficiency of peanuts were 0.345 and 0.457 kg/m3 with the fixed and center pivot irrigation systems respectively. | ||||
