Productivity and Irrigation Water Use Efficiency of Sewi Date Palm under Different Irrigation System

Abstract

This work was carried out during three successive seasons of 2018, 2019 and 2020 on Sewi date palm grown on sandy soil in a private farm at El-Baharia Oasis, Giza Governorate, Egypt, (28° 19ʹ 10ʺ N: 28° 57ʹ 35ʺ E. 130 m a.s.l.) to evaluate the effectiveness of irrigation water levels (100, 80 and 60% IR) under different irrigation system (drip and bubbler) on growth, yield, fruit quality and irrigation water use efficiency. Results showed that the studied quality parameters (except the soluble solid content (S.S.C.) of the date palm fruits were highest under the DIS, IR=100% for the tested seasons. Data referred to all the studied properties significantly affected with increasing water supply under any irrigation system. Used drip irrigation system led to produce good quality compared with bubbler ones. Evaluation of drip irrigation system with 100 % of IR enhanced yield and improved irrigation water use efficiency in the three tested seasons. Thus, this study recommends using the DIS, IR=100 % to irrigate date palm trees under El-Baharia Oasis conditions.
