Abstract It is concluded from this study that water is the main determinant of agricultural development and because Iraq is located in a region suffering from a scarcity of water resources, all efforts are directed to rationalizing the use of irrigation water by adopting modern methods of agriculture and irrigation that raise the efficiency of water use from a high return, In other words, the yield from the agricultural water unit was multiplied by the use of amino acid proline in several concentrations that contribute to reducing the water stress caused by the lack of irrigation water by using it to spray the vegetative group of plants. Including water scarcity, which is one of the non-biological environmental stresses that affect the growth and production of plants and lead to many physiological and chemical changes from the low rate of cellular division and thus leads to poor plant growth, As it leads to a loss of the water content of plant cells, causing an increase in the concentration of ions in the protein and to toxic levels, which leads to protein decomposition, cellular membranes damage, closure of stomata and imbalance of CO2, affecting the photosynthesis process. Modern techniques have been used in the present time to study the effect of water stress, where proline is one of the amino acids that have an important role in protecting plants under the influence of water stress by maintaining the osmotic balance within plant cells.
