To evaluate the effects of foliar application of amino acid on fruit yield, some elements and proline of tomato under salinity stress, a greenhouse experiment were conducted in a factorial arrangement based completely randomized design with three replicates. Five salinity levels of irrigation water including 2, 4, 6, 8 and 10 dS m1 and 3 levels of amino acid (0, 2 and 4 g L1) by foliar application method was used. Although, the results indicated that salinity of irrigation water significantly reduced fruit yield (kg per plant) of tomato, amino acid had no significantly effect on fruit yield. The highest fruit yield were obtained at the without amino acid and 2 dS m1 of salinity level. Also, statistical testing shows significant increase in proline concentration in plant leaves with application of water salinity at 8 and 10 dS m1. The highest (713.9 mg kg1) proline concentration was obtained at the 2 g L1 amino acid and 10 dS m1 of salinity level. Although, the concentration of K and Mg in plant leaves was significantly decreased by salinity, the concentration of Na in plant leaves was continuously increased with increasing salinity levels. However, results showed that salinity and amino acid had no significant effect on concentration of calcium in leaf. The highest (3.03%) nitrogen concentration in plant leaves were obtained at the without amino acid and 10 dS m1 of salinity level.]]>Abd El-Samad, H.M., M.A.K. Shaddad and N.
