A field experiment  was  conducted at the Experimental Research Farm of Faculty of Agriclture, Saba Basha,  Alexandria  Governorate,  Egypt in years 2022 and 2023, to examine how stevia rebaudiana respond to application of some salicylic acid (SA), salinity remediator (SR=Cetro_Cal) and plant density under saline soil  condition. In growing season, this factorial experiment was set up in a split plot design with three replications. The four salicylic acid (SA), salinity remediator (SR=Cetro_Cal) treatments (control= untreated, salinity remediator (Cetro-Cal) at the rate of 4 L/fed, foliar application of salicylic acid (SA) at the rate of 200 mg/l and application of SR (4 L/fed) + SA (200 mg/l) were allocated in the main plots and the three-plant spaces viz., 40 cm, 26.7 cm  and 20 cm with densities (20000, 30000 and 40000 plants/fed), respectively were distributed at random within  the subplots.The results showed that stevia plants reponsed to the different salicylic acid (SA), salinity remediator (SR=Cetro_Cal) treatments, plant densities and their interaction under study conditions. Ultimately, the findings suggested that using Citric -Cal, and SA under saline conditions will boost stevia growth , and yield at a planting density of 40000 plants /fed (20 cm apart between plant).
