A pot experiment was conducted in the open field at the nursery of Hort. Res. Institute, Giza, Egypt during 2022 and 2023 seasons to study the role of either gypsum (CaSO₄.2H₂O) or magnetic iron (Fe₃O₄) at 2.0 g/plant for each in reducing the harmful effects of saline irrigation water at 0, 2000, 4000, 6000, 8000 and 10000 ppm concentrations on orange jasmine (Murraya exotica (L.) Jack) transplants. The interaction effect between the previous two factors was also studied. Results of this experiment showed that the mean values of survival % were progressively declined with increasing salinity level to be less than 50% by 6000 and 8000 ppm levels. However, transplants watered with 10000 ppm level, even in the presence of either CaSO₄ or Fe₃O₄ died, while in their absence, transplants stayed alive only up to 4000 ppm level. Hence, survival % was improved by application of either CaSO₄ to be higher than 70% for plants irrigated with 8000 ppm level in the two seasons or Fe₃O₄ to be higher than 59% in the 1^st season and 67% in the 2^nd one by 8000 ppm salinity treatment. Similarly, were the results of the vegetative and root growth parameters and flowering characteristics, with few exceptions in both seasons. In general, concentrations of pigments, N, P, K and total carbohydrates were gradually decreased with the progressive increment in salinity level, while the application of either CaSO₄ or Fe₃O₄ significantly improved their concentrations as compared to their concentrations in the absence of their additives under the same level of salinity, with few exceptions in the two seasons. The opposite was the right concerning concentrations of proline, Cl, Na and Ca in most cases of both seasons. However, application of CaSO₄ (2 g/plant) gave generally better results as compared to 2 g Fe₃O₄/plant treatment under the same salinity level. According to the previous results, it can be recommended to amend orange jasmine (Murraya exotica (L.) Jack) transplants with calcium sulphate (CaSO₄.2H₂O) at a rate of 2 g/plant, 4 times with 2 months intervals during the active growing season under irrigation with saline water (up to 8000 ppm level) to obtain better growth performance, floriferous and high aesthetic value pot plants.
