This research was carried out at the private Farm Located at Anba Bishoy Monastry, Wadi El Natroun distract, Beheria Governorate, Egypt, during the two successive summer seasons 2017 and 2018 to study the effect of some exogenous protectants (Trehalose, Phenylalanine and proline amino acid at 0.1 ppm of each beside sprayed with water) as foliar spray on productivity and pod quality of two snap bean cultivars (Buffalo and Douglas) grown in saline soil and irrigated with drip irrigation system. Buffalo cultivar gave higher growth, yield and pod quality than Douglas cultivar under saline soil conditions. Spraying snap bean plants with Trehalose or phenylalanine increased dry weight of leaves, branches and shoot dry weight, average pod weight, average, yield/plant, total yield /fad., whereas spraying with phenylalanine increased total protein and total carbohydrates in pods. The interaction between Buffalo cultivar and spraying with Trehalose or phenylalanine increased dry weight of leaves, branches and shoot dry weight, average pod weight, yield / plant, total yield /fad., whereas the interaction between Buffalo cultivar and spraying with phenylalanine increased total protein and total carbohydrates in pods.
