The effect of magnetic water compared with saline water, nano-Mg at 100 and 200 ppm and nano-Zn at 50 and 100 ppm treatments and their combinations on lemongrass plants (Cymbopogen citratus L.) was studied during 2018/2019 and 2019/2020. Vegetative growth parameters including plant height, number of tillers/ plant, leaf area, herb fresh and dry weights were greatly affected by both studied factors. Magnetic water treatments recorded the highest values of all vegetative growth parameters

However, all nanoparticles of Mg and Zn treatments were superior than control in promoting vegetative growth parameters and the treatments of 100 ppm nano-Zn and 200 ppm nano-Mg recorded the maximum values of vegetative growth parameters. The combined treatments showed that the highest values of vegetative growth measurements were obtained in plants irrigated with magnetic water and sprayed with 100 ppm nano-Zn, in both cuts In 1 st and 2 nd seasons. N, P, K and Mg contents were significantly higher in lemongrass plants irrigated with magnetic water than those irrigated with saline water. Moreover, the treatments of 100 ppm nano-Zn exhibited the highest significant values of N, P, K, whereas 100 and 200 ppm of nano-Mg treatments were superior in recording the highest values of Mg content, in the two seasons. The combination treatments of lemongrass plants irrigated with magnetic water and sprayed with 100 ppm nano-Zn or 200 ppm nano-Mg produced the richest values of N, P and K% D.W., whereas, the treatments of magnetic water Abdel-Hamid AUJASCI, Arab Univ.
