| Abstract | ||||
| A field experiment was conducted at a private farm in newly reclaimed sandy soil at Kalabsho, El-Dakahlia Governorate, Egypt during 2018 and 2019 seasons to evaluate the effect of irrigation water type (magnetized water and non-magnetized having 6350ppm total soluble salts), different irrigation intervals (2, 4 and 6 days) and spraying with salicylic acid (0, 50, 100 and 150 ppm) on alleviating salt stress reflecting growth, yield and metabolic characters of Ocimum basilicum L. The experimental design was split- split plot replicated three times. Results revealed that MW at all examined intervals gave the supreme significant increase on all studied growth parameters, herb fresh and dry yield/fed, essential oil percentage, oil yield/fed, photosynthetic pigments, carbohydrates, protein and productivity of irrigation water in the two cuts in both seasons. Appropriate irrigation interval (4 days) significantly increased herb fresh and dry yield/fed, essential oil percentage, oil yield/fed, those were higher in the 2nd cut than 1st one through both seasons while, a remarkable decrease in the 2nd cut was observed with nonMW. Spraying with SA at all levels in both water types significantly increased most of studied attributes particularly at 150ppm. It could be concluded that MW every 4 days interacted with 150ppm SA were effectively increased growth, yield, oil %, oil yield, major components linalool and 1, 8- cineol, certain metabolic characters. Consequently MW irrigation every 4days with spraying 50ppm SA on basil under salt stress and definite water sources could be recommended for enhancing growth, qualitatively and quantitatively oil yield. | ||||
