“…The agricultural production heavily relies on local weather and climate conditions, as well as the occurrence and duration of extreme weather events [ 8 , 9 ], when making decisions about crop management. Inadequate availability of soil nutrients can have a negative impact on the biochemical and physiological performance of plants, ultimately resulting in reduced crop yields [ 10 ].…”

“…Farmers often fail to consider the suitability of a site for a particular crop, leading to the planting of crops in unsuitable areas that resulted in the loss of productivity [ 9 ]. Hence, there is a need for an effective and highly precise system to suggest which crops to plant.…”

“…Because of this, the cultivated area needs to be expanded into more marginal habitats, which are characterized by high saline levels [ 3 , 4 ]. In many parts of the world, soil salinity is a significant abiotic stress, and this problem is likely to worsen as a result of climate change, as rising sea levels could contribute to an increase in the salinization of coastal soils [ 5 , 6 ]. It significantly declines photosynthetic capacity, cell elongation, protein synthesis, and metabolic functions [ 7 ].…”

Salinity is a widespread abiotic stress that devastatingly impacts wheat growth and restricts its productivity worldwide. The present study is aimed at elucidating biochemical, physiological, anatomical, gene expression analysis, and agronomic responses of three diverse wheat genotypes to different salinity levels. A salinity treatment of 5000 and 7000 ppm gradually reduced photosynthetic pigments, anatomical root and leaf measurements and agronomic traits of all evaluated wheat genotypes (Ismailia line, Misr 1, and Misr 3). In addition, increasing salinity levels substantially decreased all anatomical root and leaf measurements except sclerenchyma tissue upper and lower vascular bundle thickness compared with unstressed plants. However, proline content in stressed plants was stimulated by increasing salinity levels in all evaluated wheat genotypes. Moreover, Na+ ions content and antioxidant enzyme activities in stressed leaves increased the high level of salinity in all genotypes. The evaluated wheat genotypes demonstrated substantial variations in all studied characters. The Ismailia line exhibited the uppermost performance in photosynthetic pigments under both salinity levels. Additionally, the Ismailia line was superior in the activity of superoxide dismutase (SOD), catalase activity (CAT), peroxidase (POX), and polyphenol oxidase (PPO) enzymes followed by Misr 1. Moreover, the Ismailia line recorded the maximum anatomical root and leaf measurements under salinity stress, which enhanced its tolerance to salinity stress. The Ismailia line and Misr 3 presented high up-regulation of H+ATPase, NHX2 HAK, and HKT genes in the root and leaf under both salinity levels. The positive physiological, anatomical, and molecular responses of the Ismailia line under salinity stress were reflected on agronomic performance and exhibited superior values of all evaluated agronomic traits.

“…The unregulated expansion of saltwater reserves for commercial shrimp farms in coastal belts is also accelerating the intrusion of salt water into drinking and irrigation water. This saline intrusion is already affecting 53% of coastal land in Bangladesh 34. Consequently, about 20 million people from coastal areas are forced to use unsafe, contaminated surface water from ponds and rivers, leading to various waterborne infectious diseases such as cholera 5…”
