Physio-Biochemical Behaviour, Water Use Efficiency and Productivity of Wheat Plants Exposed to Magnetic Field

Abstract

The aim of this study was to evaluate the capability of magnetized field in improving the growth, physiological and biochemical aspects and yield attributes of wheat crop (Triticum aestivum L. cv Giza 168) as one of the important economically strategic crops. Pot experiments were executed in a glass greenhouse belonged to the experimental farm, Faculty of Agriculture, Menoufia University, Shibin El-Kom, Egypt during two winter growing seasons 2015/2016 and 2016/2017. Magnetic treatments were magnetic grains, magnetic water and combined magnetic grains and water in addition to the control group. Vegetative growth of wheat plants was significantly increased by treating with different magnetic treatments compared to the control plants. Application of magnetic treatments caused significant increases in total leaf water content, relative water content, water use efficiency (WUE), membrane permeability and succulence degree, whereas the transpiration rate and leaf water deficit were significantly reduced. Most growth characteristics and WUE were more positively affected by the magnetized water treatment than other magnetic treatments. The concentrations of photosynthetic pigments and growth promoters (IAA, GA and Cytokinins) showed significant increases in the treated wheat plants with all magnetic treatments. A marked increase was observed in the uptake of N, P, K, Ca, Mg, Fe, Cu and Mn, but Na uptake was decreased in wheat plants by the application of magnetic field. Magnetic treatments caused a significant increase in the spike characters, grain and straw yield, and harvest index of wheat plants as well as some chemical constituents in grains compared with the control plants.

Rationalization of Water Use and Fertilization of Globe Artichoke Using Magnetic Water Irrigation

“…With the use of magnetic treatment, minerals are more easily dissolved, allowing plants to develop with sufficient nutrients and consuming less water overall (Zlotopolski, 2017. ) Our results are consistent with those of Selim (2019), who found that magnetic irrigation can reduce the need for NPK fertilizer by more than 25% and all fertilizer levels led to highly substantial increases in tuber yield under magnetic irrigation treatment.…”

“…The results are in harmony with obtained by Helaly (2018) found that application rate of K fertilizers of tomato plants was decreased from 25% to 50% by irrigation with magnetic water. Similar results were obtained with (Selim, 2019) who found that fertilizing 100% of NP K combined magnetic water achieved the highest value of potassium content in potato. Crop-water relations Amount of applied irrigation water (IWA m 3 /fed).…”

Can the use of magnetized water affect the seedling development and the metabolite profiles of two different species: Lentil and durum wheat?

“…Among these metabolites, particular attention is reserved for threalose and mannitol in the root and epicotyl of durum wheat, and glycine and GABA in the seed and root of lentil, respectively. Moreover, Sadeghipour (2016) reported that magnetic water significantly improves WUE in some plants, especially those in regions where water resources are scarce, leading to an increase in plant development and crop productivity under reduced water input, which is of great importance for an arid environment suffering from frequent droughts ( Selim and Selim, 2019 ; Liu et al., 2022 ). A deeper understanding of the effects of the MF on water and its influence on plant metabolism could revolutionize crop production under biotic and abiotic stress conditions, as well as water usage leading to crop yield improvement.…”

Growth, physiological, biochemical and molecular changes in plants induced by magnetic fields: A review

“…Plant nutrition is accumulation of naturally occurring inorganic and organic nutrients from soil that are essential for the proper functioning. Selim & Selim (2019) reported higher nutrient uptake with magnetized water in wheat; Zlotopolski (2017) noted that magnetic water treatment enhanced K + uptake in L. sativa ; Hilal & Hilal (2000b) reported higher phosphorus (P) content in citrus leaves. Algozari & Yao (2006) concluded that magnetized water application improved water movement through plant cell membranes, resulting in better water and mineral uptake.…”
