“…However, T 3 treatment ( one supplemental irrigation by 50 mm at filling stage) gave the lowest value for this trait in the first season only. These findings are in agreement with those of Erekul et al (2012), Tadayon et al (2012), Abbas et al (2014), Attia et al (2016) and Man et al (2016).…”

“…They also highlighted the importance of deficit irrigation treatment in decreasing the yield fluctuations in dry areas, and that it increased the WUE when it was applied at the grain filling stage as compared to its application at jointing or booting. Man et al (2016) concluded that suitable irrigation at jointing and anthesis increases root weight density, root triphenyl tetrazolium chloride reduction activity, and root antioxidant enzyme activity at the later stages of grain filling.…”

“…The mean grain yield of wheat in this area ranges from 0.35 to 2 t/ha based on the rainfall amount and distribution, soil characteristics and used variety, which is a way far from the country average of 7.3 t/ha . Using limited amount of water as a supplemental irrigation can improve both the crop productivity and increase the water use efficiency (Man et al, 2016), they found that the supplemental irrigation treatment of increasing the soil water content at depth of 40 cm to 65% of field capacity after jointing and 70% of field capacity after anthesis increased the grain yield and water use efficiency by above 40% and 15%, respectively in both seasons.…”

N ARID and semi-arid regions, the amount of rainfall and its …distribution greatly affect the productivity of crops in these regions. Rainfall deficits during the critical growth stages can cause a sever crop yield losses. The study was carried out at the agricultural Experimental station, Sustainable Development Center of Matrouh Resources, Egypt, during 2014/2015 and 2015/2016 rainfall seasons to evaluate the effect of different supplemental irrigation treatments on wheat yield . The irrigation treatments included rainfall only (control), one irrigation of 50 mm at tillering or booting or grain filling, two irrigations of 100 mm at tillering and booting or tillering and grain filling or booting and grain filling, and three irrigations of 150 mm at the three stages of tillering, booting and grain filling. The obtained results showed that the application of supplemental irrigation of 150 mm at the three stages of tillering, booting and filling secured the highest significantly values of plant height (61.47 cm), spike length (9.07 cm) and number of grains/spike (46.67) in the first season only, 1000 grain weight (39.72 and 48.53 g), biological yield (5.10 and 8.72 t/ha), grain yield (1.55 and 3.40 t/ha) , straw yield (3.54 and 5.35 t/ha) and WUE (0.672 and 1.08 kg/m 3 ) in both seasons, respectively. Wheat yield in the second season under the different supplemental irrigation treatments was simulated using the Root Zone Water Quality Model. Results showed a very good agreement between simulated and observed yields with a NashSutcliff Efficiency (NSE) of 0.93. It could be concluded that supplemental irrigation is highly important for achieving a good economic yield of wheat under the rainfed condition of Matrouh Governorate, moreover the RZWQM successfully simulated the wheat yield under water stress conditions.

“…This study pointed out that limited water conditions, as experienced in the first season under rain-fed conditions, reduced the WUE of grain yield, whereas maintaining the field capacity at 50%, at least at all growth stages, improved both grain yield and WUE. In fact, the improvement of WUE with SI was reported in many studies [33,62].…”

“…CTD and chlorophyll content measurements help breeders in investigating wheat yield stability since they are correlated with a number of adaptive physiological traits [28,29]. CTD is positively correlated with stomatal conductance [30], transpiration rate [5,31], water usage [30], leaf area index [32], root traits [33], and grain yield [34]. Chlorophyll content is positively correlated with photo inhibition, high membrane thermo-stability [35], and water usage [36].…”

The Effect of Supplemental Irrigation on Canopy Temperature Depression, Chlorophyll Content, and Water Use Efficiency in Three Wheat (Triticum aestivum L. and T. durum Desf.) Varieties Grown in Dry Regions of Jordan

et al. 2018

Abstract:One critical challenge facing the world is the need to satisfy the food requirements of the dramatically growing population. Drought stress is one of the main limiting factors in the wheat-producing regions; therefore, wheat yield stability is a major objective of wheat-breeding programs in Jordan, which experience fluctuating climatic conditions in the context of global climate change. In the current study, a two-year field experiment was conducted for exploring the effect of four different water regimes on the yield, yield components, and stability of three wheat (Triticum aestivum L.; T. durum Desf.) Jordanian cultivars as related to Canopy Temperature Depression (CTD), and Chlorophyll Content (measured by Soil-Plant Analysis Development, SPAD). A split plot design was used in this experiment with four replicates. Water treatment was applied as the main factor: with and without supplemental irrigation; 0%, 50%, 75%, and 100% of field capacity were applied. Two durum wheat cultivars and one bread wheat cultivar were split over irrigation treatments as a sub factor. In both growing seasons, supplemental irrigation showed a significant increase in grain yield compared to the rain-fed conditions. This increase in grain yield was due to the significantly positive effect of water availability on yield components. Values of CTD, SPAD, harvest index, and water use efficiency (WUE) were increased significantly with an increase in soil moisture and highly correlated with grain yield. Ammon variety produced the highest grain yield across the four water regimes used in this study. This variety was characterized by the least thermal time to maturity and the highest values of CTD and SPAD. It was concluded that Ammon had the highest stability among the cultivars tested. Furthermore, CTD and SPAD can be used as important selection parameters in breeding programs in Jordan to assist in developing high-yielding genotypes under drought and heat stress conditions.
