Laboratory and two field experiments were conducted to study the effectiveness of magnetic technology as well as humic acid in increasing barley productivity.In general, magnetically treated brackish water magnetic accompanied spraying with 100-ppm humic acid at 45 and 60 days of barley sowing gave the highest values in barley yield and its components compared to the control.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 [Germination (%), Germination Index (GI), Speed Germination Index (SGI), Germination Energy (EG; %), Germination Rate GR (day) and Mean Germination Time MGT (day)] and seedling traits [seedling length (cm), ten seedling dry weight (g), seedling vigour-1 and vigour-2] of barley at 14 days after sowing.Results revealed that irrigation barley plants with magnetically treated brackish-water significantly surpassed irrigation with brackish-water treatment in barley yield and its components.Under field conditions.

Laboratory and two field experiments were conducted to study the effectiveness of magnetic technology as well as humic acid in increasing barley productivity. 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 [Germination (%), Germination Index (GI), Speed Germination Index (SGI), Germination Energy (EG; %), Germination Rate GR (day) and Mean Germination Time MGT (day)] and seedling traits [seedling length (cm), ten seedling dry weight (g), seedling vigour-1 and vigour-2] of barley 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 the above-mentioned 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 of 2022/23; 2023/24 and 2024/25 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. Results revealed that irrigation barley plants with magnetically treated brackish-water significantly surpassed irrigation with brackish-water treatment in barley yield and its components. Similar trends were recoded under spraying barley plants with 50 or 100-ppm humic acid at 45 and 60 days after sowing. In general, magnetically treated brackish water magnetic accompanied spraying with 100-ppm humic acid at 45 and 60 days of barley sowing gave the highest values in barley yield and its components compared to the control. The improvement rate ranged from 11.05 - 22.99% in barley yield components. As well as the percentage increases in grain, straw and biological yield (ton fed-1) reached 39.65, 34.39 and 35.98%, respectively, compared to the control.
