Magnetic water is considered one of several physical factors affects plant growth and development. A pot experiment was carried out in research farm of the Shahre-Rey Branch, Islamic Azad University, Tehran, Iran during summer 2012 to comparison between magnetic and non magnetic water on some traits of cowpea. Results showed that Irrigation with magnetized water increased leaf, stem and root fresh and dry weight as well as total biomass as compared to ordinary water. Magnetic water also raised stomatal conductance, water use efficiency (WUE) (in term of total biomass produced to amount of water consumed), leaf area, specific leaf area (SLA), leaf area ratio (LAR), and root weight ratio (RWR) than that the control. However magnetized water decreased shoot root ratio (SRR) and also had not significant effect on leaf weight ratio (LWR) and stem weight ratio (SWR) as compared to non magnetized water. The stimulatory impact of magnetic water may be ascribed to the increasing of root growth and stomatal conductance which increase absorption and assimilation of nutrients. It appears that irrigation with magnetic water may be considered a promising technique to improving growth and WUE of cowpea.
