Abstract
Two field experiments were performed at Tag El-Ezz Research Station, Agric. Res. Center., Ministry of Agric. Egypt. to investigate the role of selected antioxidants on mitigation or alleviation the harmful effect of soil salt stress on maize plant. Soil salt stress in the first area (A₁) equal 1840 mgl^- (2.9 dsm-1); the second salt soil area (A₂) was 6080 mgl^- (9.5 dsm-1). Applied antioxidants (Ascorbic, α- Tocopherol, Humic, Seaweed extract and Salicylic) significantly increased all growth characters and yield and its components of maize plant compared with untreated plants in the two soils salt areas (A₁ and A₂) during the two growing seasons. The data also show that applied antioxidant materials were more effective in salt soil area (A₁). The data also show that applied antioxidant materials could alleviate the harmful effect of high soil salt stress levels on growth, yield and its components of maize plant. ASA and SA were more effective in this respect.
