The effect of the interaction of magnetic treatment and different irrigation water salinity on the quantitative effects on the growth parameters of Balkız Bean (Phaseolus vulgaris)

Salinity is one of the important factors that limit plant growth and development. Therefore, new tools must be developed to use saline water in agriculture and reduce its harm. One of these tools is the use of magnetically treated water to irrigate crops, which has an effective effect on the development and growth of plants and reduces the accumulation of salts in the soil. Therefore, this study was conducted to find out the effect of the interaction between magnetic treatment (MT), non-magnetic (NMT) and the salinity of irrigation water (T1 = 0.38 dSm-1 (tap water), T2 = 1.50 dSm-1, T3 = 4.50 dSm-1 and T4 = 7.0 dSm-1) on the amount of accumulated salt (ASA) and relative water content of leaves (RLWC) and quantitative effects on the growth parameters of the Bean. The study results showed that salinity stress led to a significant decrease in total plant fresh weight (TPFW), leaf relative water content (RLWC), and total plant dry weight (TPDW), While it increased (ASA) significantly. Magnetically treated irrigation water (MT) increased the (TPFW) and weight (TPDW) by 25.24% and 21.47%, respectively, while the (ASA) decreased by 22.70% compared with NMT treatment. The highest (RLWC) values were obtained at MT with T1 salinity (tap water) (0.38 dSm-1) and were 79.27%. The yield response factor (Ky) value was found 1.68 and 1.69 for MT and NMT treatments, respectively. The results showed that magnetic water has a positive effect on the quantitative effects of bean plant growth indicators and that salinity reduces plant growth.
