Irrigation Water Management of Date Palm Under El-Baharia Oasis Conditions.

Abstract

private farm in the El-Baharia Oasis area, Giza Governorate, Egypt, to study the effect of different irrigation systems (deep drip (DIS), micro jet (MIS), bubbler (BIS)) and applied irrigation water levels (IR: 100,85,70%) under mulched soil (MS) and un-mulched soil (UMS) and to determine the marketable yield (MY), crop quality parameters, actual evapotranspiration (ETa), water-use efficiency (WUE), irrigation water-use efficiency (IWUE), yield response factor (Ky) and actual crop coefficient (Kca) for date palm trees (Phoenix dactylifera L.). The experimental design was a split-split plot design with three replicates. The results showed that the MY and studied quality parameters (except the total soluble solid (TSS) content) of the date palm fruits were highest under the DIS, IR=100% and MS treatment for both seasons. For the 1 st and 2 nd seasons, the lowest seasonal ETa values were 564.41 and 526.78 mm, respectively under the DIS, IR=70% and MS treatment;the maximum date palm fruit WUE and IWUE were 3.22 and 1.55 kg m-3 and 3.61 and 1.62 kg m-3 , respectively under the DIS, IR=70% and MS treatment; the minimum Ky for date palm fruits was 0.16 and 0.12, respectively under the DIS, IR85% and MS treatment; and the minimum seasonal Kca values for the initial (I), development (D), mid-season (M), and late-season (L) growth stages were 0.29, 0.17, 0.28, 0.18 and 0.23 and 0.29, 0.15, 0.25, 0.14 and 0.21, respectively under the DIS, IR=70% and MS treatment. This study concluded that the cultivation of date palm trees under the DIS, IR=70% and MS treatment could save approximately 38% of the IR and increase the MY of date palm fruit by approximately 20 and 22% for the 1 st and 2 nd seasons, respectively, compared with the control treatment (BIS, IR=100% and UMS).

Efficient IoT-Based Control for a Smart Subsurface Irrigation System to Enhance Irrigation Management of Date Palm

“…The increases in date palm yield and water productivity with low irrigation water consumption could be due to the optimal availability of water in the S-BIS method that enhanced balanced root growth and improved soil nutrient uptake, as mentioned in [34,35]. The authors in [36] found that a subsurface drip irrigation system was the most useful regarding date palm yield and water productivity. The impact of irrigation water availability on plant growth is due to the differences in carbon uptake, stomatal conductance, and turgor pressure of plant tissues.…”

“…Climate change poses significant challenges to agricultural development, particularly in developing nations (Elsherpiny, 2023;Elbasiouny and Elbehiry, 2019;Dewedar et al, 2021). Understanding its projected impacts is crucial for future global food and water security (Abdelrahman et al, 2021), and improving irrigation management is essential for semi-arid regions (Ahmed et al, 2018;Mohamed et al, 2018). Agriculture requires careful water use to protect limited supplies, especially in inefficient irrigation practices (Aldambergenova et al, 2020).…”

Date Fruit Production and Consumption: A Perspective on Global Trends and Drivers from a Multidimensional Footprint Assessment

“…Previous studies analyzed the water footprint of date production or trade focusing on single countries [27,30,32,35,36], whereas a more structured work was realized by the FAO focusing on few countries and with a general outlook [37]. However, no study analyzed the global dynamics of the date fruit sector from multiple environmental points of view, in time series, and with a country-level resolution.…”
