Mitigation salinity water stress using magnetic technology and humic acid on productivity of Barley (Hordeum vulgare L.) growing in Maghrah region

Al-Maghrah region, 280 000 feddan, like the most locations of million and half feddan project is mainly depended on the well water of various degrees of salinity stress (4000 – 8000 ppm) that may be prevents cultivated crops from realizing their full yield. Barley is considered to be one of the best crops that can withstand difficult environmental conditions, such as salinity, as in the Al-Maghrah region. A germination experiment was conducted at Laboratory of Seed Technology Research Department, Field Crops Research Institute, Agriculture Research Centre to study the impact of seed treatments (dry seeds, hydro-seeds, and magneto-primed seeds) on germination characteristics, seedling development, and vigour of barley. Results cleared that that magnetized barley grains treatment (soaking barley grains in magnetized water for 8 hours before sowing) surpassed dry grains or hydro-grains treatment (soaking barley grains in tap water for 8 hours before sowing) in germination traits at 14 days after sowing. The improvement ranged between 5.00 – 40.68% compared to dry grains treatment and 3.52 – 24.82% compared to hydro-grains treatment in tested germination parameters. Positive effects were observed in MGT, where it is faster by 19.84% compared dry grains treatment and 11.54% compared to hydro-grains treatment. Under field conditions. Four field experiments were conducted during winter seasons (2022-2024) to alleviate salinity irrigation water stress using the application of magnetic technology combined with foliar spraying of humic acid at 45 and 60 days after sowing on the productivity of barley crops.
