Abstract

This work was carried out at a Private Farm Located at Anba Bishoy Monastry, Wadi El Natroun Distract, Beheria Governorate, Egypt during the two successive summer seasons of 2017 and 2018 to study the effect of salicylic acid concentrations (SA) (0, 50, 75 and 100 ppm) as foliar spray on dry weight, productivity and pod quality of two snap bean cultivars (Buffalo and Douglas) grown in saline soil and irrigated with drip irrigation system. Spraying snap bean Buffalo cultivar grown in saline soil with SA at 100 ppm, increased dry weight of leaves, branches, shoots/plant, average pod weight, yield/plant, total yield/fad., total protein and total carbohydrates in pods, whereas decreased proline content in leaf tissues. There were no significant differences between SA at 50 ppm and control in most studied characters of snap bean. In this regard, the increases in total yield/fad., were about 65.70 and 53.84 % for the interaction between Buffalo cultivar and SA at 100 ppm as well as 45.79 and 40.30 % for the interaction between Buffalo cultivar and SA at 75 ppm over the interaction between Douglas cultivar and control in the 1st and 2nd seasons, respectively.
