“…These results indicate silicon`s ability to induce water-stressed maize and to increase yield and the most important yield components (kernels row -1 and 100-kernel weight) and improve carbohydrate yield ha -1 , protein yield ha -1 , and oil yield ha -1 . These results confirm the previous results of Gao et al (2006), Bonder et al (2015), Amin et al (2018), Seleiman et al (2019), andTeixeira et al (2022).…”

“…They observed that silicon treatments caused significant increases in oil % and oil yield ha -1 under water stress treatments compared with nonstress. These results could be attributed to silicon, which can mitigate the damage caused by water deficit through increasing nutritional efficiencies (Bonder et al, 2015) and by stimulating greater efficiency in nutrient use for transformation into biomass, which benefits the growth of plants under water stress (Teixeira et al, 2022). Furthermore, silicon alleviates water stress by decreasing stomatal transpiration (Gao et al, 2006).…”

“…In addition, silicon application to drought-stressed maize plants enhanced the growth and yield, which could be attributed to an improved photosynthetic rate and lowered transpiration rate (Amin et al, 2018). Furthermore, Si lessened the damage caused by severe water deficits in maize plants because it kept the relative leaf water content, decreased the cell leakage index, and preserved the content of photosynthetic pigment, which increased the quantum efficiency of photosystem II, content, and use efficiency of macronutrients, thus leading to greater growth and biomass (Teixeira et al, 2022). Therefore, the objectives of the recent investigation were to (1) study the effect of water stress at flowering on some maize single-crosses, (2) determine the effect of silicon on maize and its relation to water stress tolerance, and (3) evaluate the most tolerant single crosses to each condition.…”

The use of silicon is an option for reducing the adverse effects of water deficit conditions. The recent study took place at the Agricultural Research and Experiment Station of the Faculty of Agriculture, Cairo University, Giza, Egypt (30°02′ N and 31°13′ E, with an altitude of 30 m) in two seasons of 2019 and 2020. The study’s chief objective aimed to investigate the effect of water deficit at flowering on maize and its relation to silicon spraying. The study included two water treatments: non-stress (NS) and water stress (WS); three silicon treatments: (0, 3, and 6 mM L-1); and five single-cross hybrids. A split-split plot design in a randomized complete block arrangement proceeded with three replications. Water deficit caused a significant reduction in grain yield ha-1 by 7.41%. Yield reduction resulted from substantial reductions in kernels row-1 (8.52%), 100-kernel weight (7.16%), carbohydrate % (4.79%), and carbohydrate yield ha-1 (11.88%). Silicon treatments caused notable increases in carbohydrate % by 0.57% and 0.71% and oil % by 7.69% and 19.49% due to the concentrations of 3 and 6 mM L-1 of sodium silicate, respectively. In addition, significant increases in kernels row-1 (3.01%), 100-kernel weight (3.12%), and oil yield ha-1 (18.12%) occurred under the concentration of 6 mM L-1. The most interesting observation in the study showed the noteworthy increase in oil yield/ha for all studied hybrids, ranging from 13.33% (SC-3444) to 29.41% (SC-3433). It resulted from the application of the concentration of 6 mM L-1. The hybrids SC-30N11, SC-3433, and SC-3444 proved the best hybrids, displaying tolerance to water.

Change in precipitation patterns and increase in the frequency and intensity of extreme weather events (high temperatures and heat waves) harm crop productivity. As per the future prediction, the temperature may increase by 2.5 0C by 2050 and by 2-30 C by the end of the century. The present review evaluates the impact of a rise and fall in temperature, solar radiation, and CO2 on the productivity of maize and other crops. Agronomic management practices during the crop growth period of selecting crop cultivars, date of sowing, plant population, dosage, timing, and methods of application of inputs are influenced by temperature, rainfall, solar radiation, and CO2 concentration in the atmosphere. Overall crop productivity will reduce by 50.9 % in wheat in the USA, 46% in maize in China,17% in cotton in India, and 30% in sugarcane in India. Changing the sowing date and adopting improved early and short-duration varieties of corn and other crops are becoming significant under low-cost adoption technologies to mitigate climate change. Info Crop-SORGHUM simulation model predicts that change in the sowing date of a variety in sorghum reduces the impact of climate change and vulnerability to 1- 2 % by 2020, 3-8 % by 2050, and 4-9% by 2080. The review highlights the impact of heat stress and drought on soil processes, and overall soil health. The authors conclude to implement climate adoption technologies based on Agriculture 4.0 to sustain crop production globally.

Frequent droughts have led to an expansion of irrigated common bean cultivation areas. An effective strategy to enhance water use efficiency and optimize crop growth is the application of silicon (Si) and potassium (K). However, the interaction between Si dosage, water regimes, and plant potassium status, as well as the underlying physiological mechanisms, remains unknown. This study aimed to assess the effects of Si doses applied via fertigation under various water regimes, in the presence and absence of potassium fertilization, on gas exchange, water use efficiency, and growth of bean crops in field conditions. Two experiments were conducted, one with and one without K supply, with the same treatments evaluated in both experiments. The treatments comprised a 3x4 factorial design, encompassing three water regimes: 80% (no deficit), 60% (moderate water deficit), and 40% (severe water deficit) of soil water retention capacity, and four doses of Si supplied via fertigation: 0, 4, 8, and 12 kg ha− 1. The optimal doses of Si for fertigation application, leading to increased Si absorption in plants, varied with decreasing soil water content. The respective values were 6.6, 7.0, and 7.1 kg ha− 1 for the water regimes without deficit, with moderate water deficit, and with severe water deficit. Fertigation application of Si improved plant conditions, particularly under severe water deficit, regardless of potassium status. This improvement was evident in relative water content, leaf water potential, and membrane resistance, directly impacting pigment content and gas exchange rates. The physiological effects resulted in enhanced photosynthesis in water-deficient plants, mitigating dry mass production losses. This research demonstrates, for the first time in this species, the potential use of Si in irrigated crops to enhance irrigation efficiency in areas limited by low precipitation and water scarcity. Given the global implications of climate change and the increased frequency of droughts, these findings are significant.
