“…This strategy includes the removing of soluble ion of sodium (Na + ) from the colloid's surface of clays in these sodic-saline soils via reclamation process (Shi et al 2019). Different soil amendments could be used in this reclamation process such as gypsum, phosphogypsum (Xue et al 2019), and using genetic plant tolerance to soil salinity and alkalinity (Huang 2018).…”

S TRESSED environments have long been a question of great interest in a wide range of fields. So, many considerable literatures have grown up around this theme. In Egypt, there are several common problems related to the stressed environments. These stresses include decline of soil fertility, soil salinity and alkalinity, soil water logging, salt-affected soils, soil pollution, climate change, overpopulation growth, urban sprawl, land degradation, deterioration of natural resources, etc. More generally, national income will decline and will in turn result in the spread of social and political problems. Kafr El-Sheikh governorate can be considered one of the most important areas in Egypt, which calls "the governorate of the hope and the future" due to its location and wealths. Whereas, this governorate suffers from the most common stresses in Egypt including pollution, salinity, alkalinity and waterlogging. Great problems have been recorded in Kafr El-Sheikh related to stressed environments and suggested solutions also have been addressed. Therefore, a sustainable management should be adapted for overcoming these stressed environments in Kafr El-Sheikh.

The objective of this study was to evaluate the effect of silicon (Si) on iron (Fe) deficiency in sorghum plants grown in a nutrient solution, seeing that sorghum crops are sensitive to iron deficiency and Si may alleviate this deficiency. Nonetheless, the nutritional mechanisms underlying this process have not been fully elucidated in this plant species. Treatments were arranged in a 2 × 2 factorial scheme and completely randomized block design, in the absence or presence of Si (2 mmol L −1) and under Fe deficiency or sufficiency, with five repetitions. The sources of Si and Fe were stabilized sorbitol sodium and potassium silicate (Si = 113.4 g L −1) and Fe-EDDHA chelate (Fe = 6%), respectively. The plants were cultured in pots filled with washed sand, and Si was supplied via nutrient solution at a concentration of 2 mmol L −1. The concentrations of Fe used in this study were 368 μmol L −1 for sufficiency conditions and 55.2 μmol L −1 for deficiency conditions. Our results showed that Si has a beneficial effect on sorghum plants under Fe deficiency by increasing the chlorophyll content and decreasing concentration of malondialdehyde (MDA). In addition, the application of Si increased the efficiency of translocation and utilization of Fe in plants under this micronutrient deficiency. In conclusion, Si reduced Fe deficiency in sorghum plants by increasing the concentration of photosynthetic pigments, reducing lipid peroxidation, improving the efficiency of Fe translocation and utilization, and resulting in a greater dry weight accumulation.

“…Approximately 12% of cropping areas suffer from waterlogging stress every year, and these areas are increasing [2]. Because sorghum has strong resistance to unfavourable conditions, it usually is grown in marginal areas, such as low-lying regions and flooded areas with poor drainage [3]; consequently, sorghum is frequently affected by waterlogging stress due to short-term heavy rainfall. A decline in sorghum growth and therefore a lower yield because of waterlogging have been reported in previous studies [4–5].…”

Waterlogging stress is one of the most important abiotic stresses limiting sorghum growth and development. Consequently, the responses of sorghum to waterlogging must be monitored and studied. This study investigated changes in the leaf water status, xylem exudation rate, leaf anatomical structure, leaf temperature and photosynthetic performance. Waterlogging-tolerant (Jinuoliang 01, abbreviated JN01) and waterlogging-sensitive (Jinza 31, abbreviated JZ31) sorghum cultivars were planted in pots. The experiment was carried out using a split block design with three replications. Waterlogging stress was imposed at the sorghum five-leaf stage. The leaf free water content (FWC) and relative water content (RWC) decreased under the waterlogged condition. The leaf thickness was thinner under the waterlogged condition, and the main changes occurred in the upper epidermal and mesophyll cells. Gas exchange parameters and the xylem exudation rate were also restrained by waterlogging; however, greater responses of these parameters were observed in JZ31. JZ31 had a higher leaf-air temperature difference (ΔT) than JN01. We found that changes in ΔT were always consistent with changes in the RWC and the gas exchange parameters. ΔT was significantly associated with the leaf RWC, photosynthetic rate (Pn) and transpiration rate (Tr). The results suggest that ΔT may be an indicator reflecting the water status in leaves and can be used to evaluate the tolerance of sorghum to waterlogging.
