Abstract :
The irrigation with a magnetic water increases the yield of plants by improving solubility and the nutrient availability in the soil profile. Furthermore, methanol spraying as a source of carbon dioxide, which increases the concentration of this gas around the plant, enhances the photosynthesis and plant yield. This study was conducted to evaluate soybean reaction by irrigation with different magnetic field intensities and foliar application of different concentrations of methanol in the research field at the Agriculture Faculty, Islamic Azad University-Sanandaj branch, during two consecutive years (2017–2018). The experiment was designed as a split plot in a randomized complete block design with 3 replications. Different intensities of magnetic water (0, 4, 8, 12 mTesla) were used in the main plot and foliar application of methanol concentrations (distilled water: control, 10, 20 and 30% v/v) in sub-plots. The results showed that the height of first axillary stem decreased significantly, but grain yield, biomass, oil and protein yield were significantly higher in treatments with magnetic water. Grain yield, increased by magnetic irrigation with 4, 8 and 12 mT intensities, compared to the control, by 45.56, 70.05 and 72.19%, respectively. Also the all characters were significantly affected by methanol spraying× year interactions. The interactions of magnetic water × methanol foliar applications were significant in some characters. However, based on interaction effect, the superiority of the studied traits was evident in the second year under the influence of magnetic water at 8 mT and 20% methanol.
