Abstract

A pot experiment in split plot design was conducted in the Farm of the Floriculture plants, Horticulture Department, Faculty of Agriculture, Minia University, throughout the twice experimental periods of 2022 & 2023 to study the influence of alpha tocopherol (200 ppm) and moringa leaf extract (10%) as subplot on oil production and some chemical constituents of marjoram under salinity stress (0.0, 500, 1000, and 2000 ppm NaCl), as main plot. Results showed that essential oil percent was increased with low concentrations (500 and 1000 ppm NaCl) and was decreased with the high level (2000 ppm NaCl). Volatile oil yield (plant/graze) and/season were considerably decreased with all used concentrations of NaCl. On the other side, salinity levels increased sodium (%) and proline content. Spraying alpha tocopherol at 200 ppm and MLE at 10% considerably increased the abovementioned characters in all cases, except sodium (%). Optimal outcomes were noted across all measured variables when utilizing vitamin E. Generally, significant effect was shown for all previous characters due to the interaction between salinity and alpha tocopherol and moringa leaf extract. It is advised to use a solution of alpha tocopherol (200 ppm) to spray marjoram plants in order to counteract the negative effects of salinized water, thereby enhancing the productivity of essential oil.
