- Abstract
An experiment was performed at Orman Botanical Garden, Giza, Egypt to determine the role of magnetite ore at either 2 or 4 g/pot in reducing the harmful effects of soil salinity on growth and quality of Moringa oleifera Lam. grown in soil mixture salinized with a mixture of NaCl and CaCl₂ salts at concentrations of 0, 2000, 4000, 6000 and 8000 ppm. The effect of the interaction between salinity and magnetite was also studied. The results indicated that a gradual decrease in survival percentage was observed with the gradual increments in salinity, but it was progressively increased with higher magnetite rates irrespective of salinity concentration. Connecting between magnetite at any dose and salinity up to 4000 ppm gave the highest percentage of survival rate in the two seasons. While, the lowest survival rate was recorded at 8000 ppm, especially in the absence of magnetite. A response similar to that of survival percentage occurred for vegetative and root growth traits, and leaf chemical composition, with few exceptions in both seasons. Thus, it is advised to drench soil mixture with magnetite at 4 g/pot to enhance growth and quality of Moringa oleifera transplants under salt stress.
