Soil and irrigation water salinity are among the main problems hindering
agricultural development, especially in arid and semi-arid regions, which depends
on especially surface irrigation as the main means in agriculture. The salinity lead to
low growth and production of plants, including fruit, as a result of the temporal,
azalotic, or nutrients imbalance. Salinity of the soil or irrigation water greatly
reduces the growth, productivity and quality of fruit crops by affecting their
physiological, chemical and biological functions as they cause obstruction to the
absorption of some elements by the plant and if it increased absorption of salts, it
causes ion poisoning of the cell, as well as increased salts cause less absorption of
water by the plant due to the high osmosis of soil water. There are many ways to
reduce the salt stress in the growth of fruit plants, the most important of which is
adding organic fertilizers such as humic acid or spraying with the amino acid
proline.
