Abstract

Salinity limits growing of aromatic and medicinal plant. A pot experiment was split plot design in the Farm of the Ornamental Plants, Fac. Agric., Minia Univ. during the two experimental seasons of 2022 and 2023 to evaluate the effect of alpha tocopherol (200 ppm) and moringa leaf extract (10%) as subplot on growth of marjoram under salinity stress (0.0, 500, 1000, and 2000 ppm NaCl), as main plot. The obtained data illustrated that all examined vegetative growth 
parameters were considerably decreased with levels of salinity during both seasons for the three grazing. The least results were recorded with the high salinity level (2000 ppm NaCl). Foliar application of vitamin E (200 ppm) and moringa leaf extract (10%) noticeably increased the previous characters in all cases. The best results were observed with vitamin E in all tested parameters. Generally, significant positive effect was shown for all growth parameters due to the interaction between salinity and alpha tocopherol and moringa leaf extract. It is recommended that to spray marjoram plants with alpha tocopherol (200 ppm) to mitigate bad effects of salinized water.
