High soil salinity can significantly impact the health and productivity of crops by causing stunted growth and reduced yield. When the salt concentration in the soil is elevated, it creates an osmotic pressure difference that makes it harder for plants to absorb water. This leads to dehydration even if water is present in the soil. As a result, plants may experience reduced turgor pressure, which is essential for their overall growth and upright structure.

Additionally, high salinity can directly affect the physiological processes of the plant, leading to nutrient imbalances and deficiencies, as the availability of essential nutrients can be impaired. These issues collectively contribute to stunted growth, less effective photosynthesis, and ultimately lower crop yields as the plant struggles to thrive in an inhospitable environment. This understanding is crucial for managing soil health and ensuring successful crop production in areas prone to salinity issues.
