Increasing the productivity and quality of irrigation water is a key factor in solving the greatest challenge of agriculture in arid and semi-arid regions. In this research, the effect of irrigation with magnetic water and ordinary water on different levels of drought stress was investigated on morphological, physiological and biochemical properties of corn (KSC703). The present experiment was conducted in the form of factorial experiment based on completely randomized design with four replications at the research greenhouse of Imam Khomeini (RAH) International University, Qazvin in 2016. The experimental treatments were consisted of irrigation with ordinary water and magnetic water by the amount of 75, 50 and 25 percent of field capacity with control (without tension). The results showed that the measured traits were significantly affected by irrigation treatment, so that, the highest stem diameter (1.87cm), the maximum leaf width (5.92cm), the highest plant height (126cm), the highest amount of chlorophyll (45.97), the highest percentage of nitrogen (4.05 percent), phosphorus (0.39 percent) and potassium (3.78 percent) of corn leaf, was observed in the treated plants by magnetic water and without tension conditions. The highest amount of total protein (0.63 milligram per gram dry leaf) was obtained from magnetic water treatment and irrigation by the amount of 75 percent of the agricultural capacity. In general, magnetic water had a positive and significant effect on the most measured traits and could somewhat reduce the negative effect of low water in corn. |
