“…The testing location used in the present study represents one of the major emerging wheat‐producing regions in Egypt. Furthermore, it also represents one of the newly reclaimed lands that undergo intensive agriculture systems (Abdallah et al, 2018). The use of drainage or low‐quality groundwater increased soil salinity and sodicity in several fields in this region.…”

In arid and semi‐arid regions, soil salinity and sodicity are the most common constraints to agriculture production, in particular in North Africa. The effect of gypsum application has been widely studied in saline‐sodic soils. However, the gypsum amendment's influence on the performance, productivity and mineral absorption of salt‐sensitive and tolerant wheat cultivars in both saline‐sodic and normal soils under field conditions has not yet been investigated. A two‐season (2016–17 and 2017–18) field experiment was undertaken to investigate the impact of gypsum on wheat growth, yield and minerals uptake for salt‐tolerant and sensitive cultivars grown in normal (EC = 1.3 dS m−1, pH = 8.4 and ESP = 7.1–8.0%) and saline‐sodic soils (EC = 5.8–6.2 dS m−1, pH = 8.8 and ESP = 19.3–22.4%) in the western Nile delta, Egypt. The gypsum requirement was applied to decrease the initial ESP from 19.3–22.4 to 10.0% was calculated for 0.3 m soil depth. Gypsum application (6.0 and 4.7 ton ha1, for the first and second season, respectively) reduced soil pH, EC and ESP of saline‐sodic soil by 31.6, 7.3 and 39.0%, respectively (two‐season mean). Furthermore, gypsum application increased Ca2+, Mg2+ and K+ in the flag leaf by 54.7, 24.5 and 45.7%, respectively (2‐season mean) under saline‐sodic soil. While, in the normal soil, gypsum application increased Ca2+, Mg2+ and K+ by 67.3, 32.7 and 78.7%, respectively. In contrast, gypsum applications decreased Na+ and Cl− content by 17.2 and 15.0% and by 40.0 and 35.5%, respectively, in the saline‐sodic and normal soil, respectively. Under saline‐sodic and normal soils, gypsum application significantly increased the K/Na ratio by 90.0 and 175.2%, respectively (2‐season mean). Interestingly, across cultivars, gypsum amendment increased grain yield by 20.7% (6.9 to 8.3 t ha−1) for normal soil and by 8.0% (5.8 to 6.3 t ha−1) for saline‐sodic soil. The positive impact of gypsum was more pronounced under the normal soil and for the salt‐sensitive cultivars than in saline‐sodic soil and for salt‐tolerant cultivars. Growers can cultivate salt‐tolerant cultivars and use gypsum as a precaution to reduce saline‐sodicity build‐up and to increase nutrient absorption.

“…Rice ( Oryza sativa L.) is one of the most cultivated cereals and an important source of carbohydrates to two‐thirds of the global population (Parthasarathi et al ., 2018). Approximately, 75% of the produced rice is cultivated under irrigated conditions and predominantly in a flood irrigation system (Abdallah et al ., 2018).…”

Iron (Fe) toxicity is one of the most frequent abiotic stresses in rice, as it affects from 15% to 30% of the total production. Brassinosteroids (BRs), including 24‐epibrassinolide (EBR), regulate ion homeostasis and improve the antioxidant system. The aim of this research was to determine whether EBR can contribute to the tolerance of rice plants exposed to Fe toxicity and to evaluate the possible effect on anatomical characteristics, nutrient concentrations, the antioxidant system, and gas exchange. The experiment was randomized with four treatments, two with different concentrations of Fe (250 and 6250 μM, control and toxicity, respectively) and these were either supplied with EBR or not (0 and 10 nM EBR, described as −EBR and +EBR, respectively). Treating plants grown under Fe toxic conditions with EBR caused an 70% increase in root aerenchyma area, compared to plants without steroid treatment. Our results revealed that EBR treatment could mitigate the deleterious effects of Fe toxicity in rice plants, by modulating the aerenchyma area, which contributes to the formation of an oxidative barrier and reduce the Fe mobilization at the root surface. Plants that were exposed to Fe toxic concentrations and treated with EBR showed (1) an increase in the enzyme activities of superoxide dismutase, catalase, ascorbate peroxidase and peroxidase, (2) mitigation of oxidative damage and (3) increased scavenging of reactive oxygen species. Finally, EBR alleviated the negative impacts induced by excess Fe on the net photosynthetic rate and the instantaneous carboxylation efficiency. These benefits were directly related to higher electron transport and stomatal density and indirectly linked to the protection mechanism exercised by the antioxidant enzymes on photosynthetic machinery. We conclude that EBR is able to confer tolerance to Fe toxicity in rice plants.
