“…However, these traits for straw yield haven't clear response trend to irrigation regimes. These results are in harmony with those of El-Hadidi et al (2015) who stated that WP increases under DI, relative to its value under full irrigation.…”

Improving the irrigation water productivity of wheat under water shortage and high evaporation such as New Valley conditions is crucial. Two field experiments were carried out during the two successive winter seasons of 2014/2015 and 2015/2016 on the Experimental Farm, Agricultural Research Station at El-Kharga, the New Valley Governorate. The experiment was laid out in strip plot design with four replications. Irrigation methods (flood, sprinkler and drip) were allocated horizontally; while, irrigation regimes (25, 50 and 75% soil moisture depletion, SMD) were arranged vertically.Results reveal that applying drip and sprinkler irrigation methods increased grain yield of wheat by 19.86-33.72% and 4.83-13.14% in both seasons, respectively as compared with flood irrigation method.The maximum mean values of grain yield (2825 and 2609 kg fed -1 ) were obtained under the 25% SMD regime in the both seasons.Seasonal ET a mean values were 1614 and 1706 m 3 fed -1 under flooding irrigation method; 1586 and 1676 m 3 fed -1 under sprinkler irrigation method; 1559 and 1653 m 3 fed -1 under drip irrigation method in the first and second seasons, respectively.The crop water productivity (CWP) mean values for grain and straw yields of wheat were 1.67 and 2.77 kg m -3 in the first season being 1.64 and 2.60 kg m -3 in the second season, respectively. The IWP followed the same trend; the values of irrigation water productivity (IWP) were 1.42 and 2.36 kg m -3 in the first season and 1.40 and 2.22 kg m -3 in the second season for grain and straw yields of wheat, respectively.Comparing with flood irrigation method, the gross return (grain + straw) per consumptive water in ET unit under drip irrigation was increased by 23.97 and 32.04%. Moreover, this revenue was enhanced to 81.42 and 94.06% for irrigation water unit in both seasons, respectively.It could be concluded that applying drip irrigation at 50% SMD improved yield and water productivity of wheat as well as saving irrigation water.

“…Given prevailing water limitations and growing competition for water resources from industry and urban development, water for agriculture in general and for wheat production specifically must be used more efficiently. This may be achieved by restricting wasteful overhead sprinkler applications (i.e., use of drip irrigation) [42], by encouraging the use of effective agronomic production methods (i.e., mulch culture) [43], and by using water-efficient wheat genotypes [44]. Yet another strategy concerns retaining water in the soil matrix by increasing organic matter contents.…”

The Contribution of Agronomic Management to Sustainably Intensify Egypt’s Wheat Production

In Egypt, recent shortfalls in the wheat supply from Russia and Ukraine have necessitated substantial increases in domestic production. As agricultural practices influence the yield of bread wheat, we assessed current production strategies in the wheat-based systems of Egypt and investigated their effects on wheat productivity in four study areas in the Nile Delta. We used a multi-stage random sampling technique to select 246 wheat-producing farmers and applied structured questionnaires to assess farming practices and crop performance attributes. Data were analyzed by using descriptive statistics, analysis of variances, and multiple regression models. Wheat farmers were on average 56 years old with about 30 years of farming experience. Land holdings were rather small, with an average of 1.05 hectares and a mean wheat yield of 6.4 metric tons (t)/hectare (ha). Farmers devote <20% of their cropland area to wheat. Of the large observed variation in wheat yield (4.2–8.5 t/ha), 59% was explained by differences in applied cropping practices in the multiple regression model. The application of mineral fertilizers was mostly inappropriate and unbalanced, with an overuse of nitrogen and phosphorus, the complete absence of potassium and micronutrient fertilizers, and insufficient rates of applied organic amendments. The type of the preceding summer crop and the irrigation frequency were found to be the most influencing factors, explaining 7.5% and 38% of the variation in wheat yields. The majority of farmers with low wheat yields irrigated their crops twice per season, while only 7% of high-yielding farmers applied the recommended irrigation frequency of >5 times per season. Most farmers had poor knowledge of modern agronomic practices and inadequate access to information. To enhance domestic production in Egypt, there is a need for fiscal incentives, permitting or stimulating wheat-producing farmers to devote larger shares of their cropland to wheat cultivation. In addition, policies must enable wheat producers to improve their productivity by implementing adequate and sustainable agricultural practices such as crop rotations, balanced mineral nutrient supply, and the use of organic amendments. However, the most important factors are interventions and technologies that improve provision and increase the use efficiency of irrigation water.

Salinity and water shortage are the most important factors limiting crop productivity, so increasing the productivity of salt-affected soils is important to address the global food gap. Two field experiments were conducted under typical farm conditions in the North Nile Delta to study the effect of planting methods and gypsum application on wheat yield and water productivity under a range of water and soil salinity levels. In the first experiment, wheat was treated with gypsum (25%, 75%, and 100% gypsum-requirement) with moderate or high salinity in soil and water. The second experiment was conducted for two seasons at two sites to test three planting methods (flat, 60-cm furrows, and 120-cm raised-beds) under normal or high salinity levels of both soil and water. The results showed that gypsum alleviated the hazardous effects of salinity stress on grain yield. Raised furrows or beds under higher salinity levels increased soil salinity, and soil salinity was slightly increased with flat plots. Higher yields, water savings, and water productivities were achieved with raised furrows or beds under normal salinity. To improve yield under normal salinity conditions, raised beds are the recommended planting method. Furthermore, gypsum application in cultivated fields can mitigate the negative effects of salinity stress.
