“…Drought stress is one of the significant environmental stress factors affecting plant growth and development ( Singh et al., 2017 ). The lack of soil moisture may partially contribute to the negative impact on plant growth and development ( Gong et al., 2003 ; Singh et al., 2017 ; Abd El-Mageed et al., 2022 ). This was evidenced by the reduction in all growth parameters reported in the current study.…”

“…Following drought stress, the increased rate of SOD activity was lower in drought-tolerant genotypes than in drought-sensitive genotypes; however, the increased rate of CAT and POD activity and total antioxidant capacity was higher in the drought-tolerant genotypes ( Simova-Stoilova et al., 2008 ; Hussain et al., 2021 ; El-Ashry et al., 2022 ; Khedr et al., 2022 ). Thus, the production of H 2 O 2 due to the activated SOD enzyme can function in oxidative stress signaling and can act as a secondary messenger to protect reactions leading to induced CAT and POD activity in plants ( Anjum et al., 2011 ; Hussain et al., 2021 ; Abd El-Mageed et al., 2022 ; El-Ashry et al., 2022 ). The drought-induced oxidative stress tolerance may be conferred by the high stability and increased CAT and POD activities ( Tian et al., 2012 ).…”

Rice (Oryza sativa L.) is a major cereal crop and a staple food across the world, mainly in developing countries. Drought is one of the most important limiting factors for rice production, which negatively affects food security worldwide. Silica enhances antioxidant activity and reduces oxidative damage in plants. The current study evaluated the efficiency of foliar spray of silica in alleviating water stress of three rice cultivars (Giza178, Sakha102, and Sakha107). The seedlings of the three cultivars were foliar sprayed with 200 or 400 mg l-1 silica under well-watered [80% water holding capacity (WHC)] and drought-stressed (40% WHC)] conditions for two summer seasons of 2019 and 2020. The obtained results demonstrated that drought stress caused significant decreases in growth, yield, and physiological parameters but increases in biochemical parameters (except proline) of leaves in all rice cultivars compared to well-irrigated plants (control). The roots of drought-stressed seedlings exhibited smaller diameters, fewer numbers, and narrower areas of xylem vessels compared to those well-watered. Regardless of its concentration, the application of silica was found to increase the contents of photosynthetic pigments and proline. Water relation also increased in seedlings of the three tested rice cultivars that were treated with silica in comparison to their corresponding control cultivars when no silica was sprayed. Foliar application of 400 mg l-1 silica improved the physiological and biochemical parameters and plant growth. Overall, foliar application of silica proved to be beneficial for mitigating drought stress in the tested rice cultivars, among which Giza178 was the most drought-tolerant cultivar. The integration of silica in breeding programs is recommended to improve the quality of yield and to provide drought-tolerant rice cultivars under drought-stress conditions.

“…Grain sorghum ranks fourth in Egypt's major cereal crops (Hafez et al, 2021;Abd El-Mageed et al, 2022) in terms of area and production, next to wheat, rice, and maize. It has a cultivated area of about 150,811 ha, producing about 802,128 t grains (Economic Affairs Sector, 2020).…”

Drought is a severe causal factor of reduced crop yields than other abiotic stresses. Therefore, four sorghum genotypes underwent evaluation for their drought tolerance under three irrigation levels (100%, 70%, and 40% from evapotranspiration) under three sowing dates at the Higher Institute for Agricultural Cooperation Farm, Regwa region, Alexandria Desert Road, Egypt, to study the mean performance of grain yield plant-1 and transcriptomic analysis. The performance results reported that Shandaweel-6 and Hybrid-306 revealed the highest drought-tolerant hybrids, while Dorado and Giza-113 cultivars showed the lowest. The transcriptomic profiling of sorghum under normal and drought stress used the RNA-Seq method. Two differentially-expressed genes (DEGs) in leaves respond to drought. In the DREB2 case, the greatest average fold change showed 10.7 and 9.3 for the tolerant hybrids, Hybrid-306 and Shandaweel-6, respectively. Both genotypes performed significantly higher than the average fold change calculated for the sensitive genotypes Dorado and Giza-113 cultivars. This study contributes to a better understanding of the molecular basis of drought tolerance of sorghum and promotes sorghum improvement.

“…K deficiency induces negative effects on the growth and productivity of wheat crop; this reduction may be magnified under adverse conditions such as salinity and soil contamination with heavy metals like cadmium. Salinity is a major abiotic stress, diminishing the development and yield of several crops worldwide (Abd El-Mageed et al 2022;Semida et al 2014;Shaaban et al 2022). Increasing osmotic potential due to salt stress restricts the availability and uptake of water by plants (Rady et al 2020).…”

Potassium is an essential macronutrient, where its availability regulates numerous biochemical, phenological, and physiological responses in plants. Synchronizing potassium supply with plant demand is a key factor to enhance growth and grain production of wheat grown in cadmium-contaminated saline soils. Field experiments were conducted in El Fayoum province, Egypt, between latitudes 29° 02′ and 29° 35′ N and longitudes 30° 23′ and 31° 05′ E, during the cropping seasons of 2017–2018 and 2018–2019 to determine the influence of different applied potassium rates and times on nutrient uptake and wheat yield grown under Cd-contaminated saline soil (ECe = 8.53 dS m−1 and Cd = 18 mg kg−1 soil). Four K levels (K0, K40, K80, and K120 representing 0, 40, 80, and 120 kg ha−1) were applied at different application times [full dose (basal) at sowing (100% S), two equal split doses at sowing and flowering stage (50% S + 50% F), and full dose at flowering stage (100% F)]. The experimental treatments were arranged in a randomized split complete block design and replicated three times. The applied K rates, times, and their interaction induced significant differences in nutrient uptake and physiological responses which in turn improved the growth and yield of the wheat crop. Potassium addition with 120 kg ha−1 at two equal split doses (50% S + 50% F) resulted in the highest values of plant height (97 cm), Fv/Fm (0.83), PI (5.49), SPAD (58.63), MSI (34.57), seed yield (5.04 t ha−1), straw yield (9.04 t ha−1), and water productivity (0.99 kg m−3). Similarly, the uptake of N, P, K, Ca, Mg, Fe, Mn, and Zn was increased, while the uptake of Na and Cd decreased as the K supply increased under the split application. The addition of potassium by 120 kg ha−1 in two equal split doses at the sowing and flowering stage could be a valuable approach to improve yield and yield quality of wheat crop grown under cadmium-contaminated saline soils.
