Shortage of water resources, development of drip irrigation (T-Tape) method in the arid and semi-arid regions, enhancement of Nano fertilizer application in agriculture, the effect of magnetic water on yield and water use efficiency for crops led to carry out a research for this purpose. Therefore, the present study investigates the possibility of increasing yield and water productivity of soybean crop using drip irrigation (T-Tape) with Ferro-iron fertilizer under magnetic and non-magnetic conditions in a complete randomized block design with three replications in the Kashmar city, East of Iran during 2016. Main treatments consisted of two types of magnetic (M1) and non-magnetic water (M2) and sub-treatments including four levels of Nano-iron fertilizer (0 or no fertilizer: N1; 0.2:N2; 0.4:N3 and 0.6:N4 g/liter per unit area). The results showed that the effect of Nano-iron fertilizer and magnetized water on grain yield, biomass and water use efficiency were significant at 5% level. Although, the interaction effect of magnetic water and nano-iron fertilizer was not significant on crop properties. Irrigation with magnetized water and Nano-iron fertilizer at 0.6 glit-1m-2 increased the grain yield (with the production of 3670 kg/ha) 25% as compared to the control treatment. The lowest grain yield was obtained in non-fertilizer and non-magnetic water treatment with the production of 2.565 kg/ha. The water use efficiency of soybean was varied from 0.49 to 0.71 kg/m3, which were corresponded to M2N1 and M1N4 treatments, respectively.
