| Abstract | ||||
| This study was conducted at North Sinai Research Station Farm, Desert Research Center, El-Sheikh Zwaid city during the two consecutive seasons of 2014 and 2015 to improve Origanum syriacum L. plant growth and productivity under saline water irrigation (about 3000 ppm) stress conditions. Humic acid (0, 2, 4 and 6 kg.fed-1) were added with irrigation water. Different concentrations of acetyl salicylic acid (0, 500, 750 and 1000 mg.l-1) were sprayed on plants. Experimental design was split plot design with three replicates, since humic acid concentrations were arranged in main plots, while acetyl salicylic acid levels were assigned in sub-plots. Obtained results showed that the highest values of vegetative growth parameters, volatile oil yield and chemical composition were gained with the interaction treatments of 750 or 1000 mg.l-1 acetyl salicylic acid combined with 6 kg.fed-1 humic acid without significant difference between both treatments. So that, our recommendation is to spray Origanum syriacum L. plants grown under saline water irrigation stress with 750 mg.l-1 acetyl salicylic acid with applying 6 kg.fed-1 humic acid to avoid the depressive effect of salinity on growth and productivity of Origanum syriacum L. plants. | ||||
