Abstract
Lysimeter experiments were carried out during two successive seasons 2020/21 and 2021/22 at Sakha Agricultural Research Station, Kafr El-Sheikh Governorate, Egypt. A split split–plot design with three replicates was utilized. This study aimed to study the effect of foliar spraying with silicate potassium and antioxidants to increase the productivity of wheat crop (Triticum aestivum L.) and reduce the harmful effect of salinity on two cultivars of wheat (Sakha 95 and Misr 3) under stress condition, to determine the most suitable materials for spraying under these conditions. The obtained results showed that the soil salinity caused a marked reduction in physiological and biochemical characteristics of wheat plants, which decreased the biological yield and grain yield compared with normal soil in the two seasons, respectively. Sakha 95 cultivar gave the highest results of plant height, spike length, and 1000-kernel weight, biological and grain yield under both the influence of salinity and normal soil salinity. Application of ascorbic acid (ASA) recorded the best treatment for counteracting salinity stress in terms of wheat yield and its attributes that it recorded the highest increase in the content of proline, peroxidase (POD), and catalase (CAT), followed by potassium silicate and salicylic acid. Also, it increased the mean values of N, P and K in the 1st and 2nd seasons, respectively while, the mean values of Na% were decreased in both seasons, respectively compared with untreated plants. Therefore, planting the Sakha 95 cultivar with foliar spraying by ascorbic acid is recommended to increase wheat production under salt stress.
