| Abstract | ||
| This work was carried out during three successive seasons of 2021, 2022 and 2023 on Barhi date palm grown on sandy loamy soil in a south valley agricultural research station (Toshka) at Abo simple, Aswan governorate, Egypt to evaluate the effectiveness of irrigation regulated water levels (100, 80, 70 and 60% IR) on growth, yield, fruit quality and irrigation water use efficiency. Results showed that the studied growth traits and quality fruit parameters of the date palm were highest under the 100% or 80% for the tested seasons. Data referred to all the studied properties significantly affected with increasing water supply. No significant difference due to irrigate via irrigation regulated at 100 or 80% IR. In addition, irrigation levels with 70% or 80% of IR enhanced irrigation water use efficiency in the three tested seasons. Thus, this study recommends using the 70 to 80 % of IR to irrigate Barhi date palm under Toshka conditions to get the high yield with good fruit quality, in addition increasing the water use efficiency. | ||
