Problems of salinization and water logged soils in Tunisia already largely affect on part of irrigated areas of the Mejerda Valley and the Center of Tunisia and the oasis in the south. On the geochemical aspect, sodium chloride paths dominate all the saline soils in these areas of Tunisia, as well as, less soluble salt as calcium carbonate and gypsum. The major alkaline cations in these soils are calcium, magnesium, sodium and potassium combined with the anions of chlorides, sulfates or carbonates, which differ in their solubility. For practical work, A field experiment was carried out in Wadi Al {u2013} Natroun land, the average salinity of the soil past extract is 2.65 dS/m which it is irrigated with saline water of 8.61 dS/m during the successive seasons 2014-2015 for the purpose of. A) study to reduce the effects of salt stress on the morphological and physiological characteristics of maize plant as one of the salinity sensitive plants and the productivity of the vegetable crop and grain by spraying three different levels of the concentration of proline amino acid (15 - 30 - 45 ppm) on the plant during the different stages of growth compared to a control treatment not treated with proline amino acid (0 ppm). B) The efficiency of water use for productivity in the four treatments. The results indicated that : The effect of the use of proline amino acid in the three treatments was better than control treatment, which has not been used with any concentration of proline on the morphological characteristics of the plant from where of number of plants grown, diameter of the stem, leaf area index, plant height and fresh weight of maize plant at all stages of growth ,as well as, the morphological characteristics of the maize cob from where of the outside look of the maize cob, the length and diameter of the cob, the number of rows and grains in the cob and the weight of a thousand grain, adition to the physiological characteristics of the plant from where of the percentage of accumulation of proline acid, the percentage of macro and micro, the ratio between the accumulation of sodium to potassium and the calculation of the Grain and dry matter yield of maize crop of these treatments, and the calculation of the efficiency of water use treatments | ||
