“…The study area is located in Upper Egypt, covers about 400 ha as part of El-Minia Governorate, along the westside of Nile Valley and in between the Western and the Eastern deserts. El-Minia Governorate is one of the main sugars producing areas in Egypt, producing more than 20% of the country's total (Ouda et al, 2020). In El-Minia Governorate (latitude 28.05º, longitude 30.44º and elevation 40.00 m), a part of Abu-Qurqas district lies between three villages (Saqiet Mousa Village, Nazlet Makeen Village and Nazlet Hamzawy Village) was carefully chosen as it is one of the major sugarcane monoculture areas besides its proximity to New Abu-Qurqas Sugar Factories (Map 1).…”

Soil deterioration and yield decline are the main factors affecting the environmental sustainability of long-term irrigated sugarcane monoculture. This research was conducted to detect changes of soil physical, chemical and physicochemical quality parameters associated with intensive irrigated sugarcane monoculture with groundwater for long term. Sugarcane monoculture resulted in a severe impact on some soil physical indicators of soil quality as increased the soil bulk density and reduced soil clay content, decreased soil aggregate stability and the water content at the field capacity causing decreases in soil porosity and decline in soil fertility. Significant impacts on some soil chemical indicators of soil quality were also recorded as reduced soil organic matter content and increased soil pH and EC producing soil salinity. Fields under long-term irrigated sugarcane monoculture had low OM values ranged from 2.09 to 2.61% while areas under crop rotation had the highest OM values ranged from 2.62 to 3.39%. Fields under sugarcane monoculture system had higher pH, EC and SAR values ranged from 7.96 to 8.41, from 2.98 to 4.22 dS m -1 and from 7.75 to 11%, while fields under crop rotation system had the lowest pH, EC and SAR values ranged from 7.64 to 7.92, 1.41 to 2.42 dS m -1 and from 4.51 to 5.86%, respectively. From these results, it could be concluded that long term sugarcane monoculture has significantly deteriorated soil physical and chemical properties indicating the urgent demand for more sustainable management practices to preserve soil quality.

“…Its efficiency decreases the amount of water loss through effectively decreasing the amount of leaching and evapotranspiration, compared to other irrigation systems. This results in a higher income per water unit (FAO, 2007;Ouda, Zohry, & Noreldin, 2020). The adoption of the drip water system minimized water stress, which is revealed by lowering the leaf water potential.…”

Drip vs. Mini-sprinkler Irrigation System on Leaf Water Potential and Various Vegetative Attributes of Annona squamosa under Lebanese Conditions

et al. 2021

Recently, the introduction of tropical crops in Lebanon represented a challenge for farmers and researchers. Constraints to the adaptation of such crops, to climatic and soil conditions were found. In this study, an orchard of Annona trees (Sq/Ch combination) was irrigated by minisprinkler system and drip system, and compared to a control (not irrigated) over two consecutive years (year 4 and year 5 of the project). Compared to the control, plant height and leaf number were improved the most in year 5 by drip irrigation. Leaf water potential that peaked in the summer season in control plants (-1.8 MPa) was the lowest in plants irrigated by drip system (-1.3 MPa). No significant difference was observed between treatments in the number of lateral shoots. TDM of plant parts was improved by drip irrigation in both experimental years by 81 g (year 4) and by 258 g (year 5). LMF was significantly enhanced in year 5 by the mini-sprinkler system. RMF was the highest in trees irrigated by drip irrigation (0.265 g/g) and the lowest in the control (0.227 g/g). SMF was the highest in control trees in both experimental years. It seems that drip system presented an optimal method for the irrigation of annona.

“…Where water is the primary factor limiting wheat output, optimizing water usage efficiency will be critical. Water scarcity in irrigated agriculture, inadequate irrigation, and infrequent rainfall all contribute to water deficit stress (Ouda et al, 2020). Al-Zahy et al (2020) reported that increasing irrigation intervals expose wheat plants to drought stress which can decrease grains spike weight, number of spikes/m 2 , 1000grain weight, straw yield, grain yield, and protein %.…”

This study was performed at El-Gemmeiza Agricultural Research Station (ARC), El-Gharbia Governorate, Egypt, during 2019/2020 and 2020/2021 growing seasons to evaluate effects of three irrigation intervals on grain yield and yield components and water use efficiency of ten wheat cultivars. Four replications of a split-plot design were carried out, the main plots were included three irrigation intervals i.e., irrigation every 20, 30 and 40 days and the ten bread wheat cultivars i.e.,
