Effect of Irrigation with Magnetized Water on the Yield and Biomass of Soybean var. DPX under Water Deficit and Salinity Stress

In areas facing water shortage, increasing water productivity is the key to overcome the greatest challenge in the agricultural sector. The present field experiment aimed to evaluate the effect of different irrigation water depths and salinity of magnetized and non-magnetized water on grain yield, biomass, height, protein, and oil content of soybean variety DPX. The experiment was performed as factorial based on randomized complete block design with three replications in Aliabad, Golestan province, in 2013. The treatments consisted of three levels of water volume (100%, 75% and 50% of soybean water requirement) and three salinity levels (0.7, 5, and 10 dS/m). The results showed that magnetized water caused irrigation water quality to be improved. Therefore, magnetization of irrigation water resulted in the highly significant increase in the grain yield, biomass, height, protein, and oil content of plant under water deficit and salinity stress treatments (p
