Impact of Magnetic Treatment of Irrigation Water on the Growth and Yield of Tomato

Abstract

This study was carried out to determine whether magnetic treatment of the irrigation water may actually enhance vegetative growth and yield of tomato. Three magnetic flux densities of 124, 319 and 719 G (treatments T1, T2 and T3) were used to treat the water and a control experiment (Tc) which was irrigated with non-magnetically treated water was also set up. The magnetic field was produced by an electromagnet that had a variable voltage unit varying the voltage from 4 to 12 V. The tomato were planted in buckets, kept in a transparent garden shed for 130 days and irrigated with magnetically treated water and non-magnetically treated water. A completely randomized design experimental layout was used in this study and each of the three treatments was replicated seven times. The results indicated that tomato crop irrigated with magnetically treated water grew faster than that of the non-magnetically treated water and the stem diameters were bigger than those of control. The heights of tomato plants (T1, T2 T3 and Tc) after 47 days were 560.0, 556.4, 588.6 and 469.3 mm respectively. The total yield after 130 days of survey for T1, T2 T3 and Tc were 892.1, 1075.8, 1045.7 and 637.7 g respectively. The percentage increment in yield from the plants treated with magnetically treated water varied from 39.9 to 68.7% compared to the yield from untreated water.

Impact of Magnetized Water Irrigation, Soil Mineral Fertilization and Foliar Spraying with Nanomaterial on Potato Plants.

“…It increases electroconductivity, the solubility of salts and decrease pH moreover it plays an important role in insecticides, fungicides and herbicides, as well as, magnetized water caused increments in microorganism's number which reflected on the positive effect of the aforementioned parameters. These results agree with those recorded by Abd El-latif et al (2015), Yusuf and Ogunlela (2015) and Abdel .…”

“…Meanwhile, Elsayed (2014) obtained that irrigation broad bean plants with magnetized water caused significant increments in chlorophylls, carotenoids and photosynthetic activity over the irrigation by normal water. Yusuf and Ogunlela (2015) reported that irrigation with magnetized water affected the vegetative growth of tomato by inducing the rate of growth, decrease the time to maturity and enhanced yield. By the same token, Abd El-latif et al (2015) on strawberry showed that irrigation with magnetized water + 50% NPK of recommended dose gave the maximum values of chlorophylls, carbohydrates, yield and TSS.…”

Effect of Magnetic Treatment of Irrigation Water on Growth and Yield of Maize under different Water Deficit Conditions

“…The value of tTab was obtained from Montgomery et al (1998). The result obtained in this study was in agreement with the work conducted by the previous researchers that MTW increased yield as shown in Figure 4 (Maheshwari and Grewal, 2009;Babu, 2010;Hozayn and Abdul-Qados, 2010;Dhawi, 2014& Ogunlela, 2017b.…”

Effects of Magnetically-Treated Water on Tomato Yield and Uptake of Heavy Metals Under Water Deficit Conditions

“…Sum of square treatment (SST R ), Sum of square total (SST O ), Correction factor (C.F) and Sum of square error (SS E ) were computed using Equations (9), (10), (11) and (12), respectively. The Analysis of Variance (ANOVA) was based on values generated from Equations (9), (10) and (12). (12) where T i is the total yield of each treatment, t is the number of treatments used, X is the individual yield based on the treatment used, G is the total yield from all the treatments used and N is the number of observation which is equal to the product of number of treatments (t) and number replications (r)…”

“…[11] pointed out that magnetic treatment of irrigation water could alleviate adverse effect of water stress (water shortage) in crop because it reduces free radicals production and antioxidant enzymes activity. Magnetically-treated water increases evapotranspiration rate and water use efficiency [12]. This means that crop irrigated with magnetically-treated water could withstand water shortage, absorb little water available in the soil and the yield is not affected as crop irrigated with non magnetically-treated water.…”
