Magnetically Treated Irrigation Water Improves the Production and the Fruit Quality of Strawberry Plants (Fragaria × ananassa Duch.) in the Northwest of Morocco

Abstract

Utilization of magnetically treated water has been investigated and applied in many countries such as Russia, Australia, Israel, China and Japan. Studies have shown that the magnetic field is used as a safe alternative to improve plant growth and development. Although the properties of magnetically treated water have received a great deal of interest in recent years, there are no studies conducted in Moroccan agricultural conditions. The present study aimed at gaining more insight on the effect of magnetically treated irrigation water (MTIW) in the northwest region of Morocco, on the yield of strawberry plants (Fragaria × ananassa Duch. cv. Camarosa) and its components. The experiments were conducted in situ, during two crop seasons (2011-2012 and 2013-2014). The results confirm that physical treatment of irrigation water by a static magnetic field improves the yield and quality of strawberry fruits. The percentages of increase in number of flowers, number of fruits, fruit yield and quality of export production per 100 plants were 27.4%, 30.9%, 34.8%, 24.3%, respectively, compared with normal irrigation water (average over both crop seasons). These results suggest that irrigation with MTIW improves the production as well as the quality of the strawberry fruit, thus water use efficiency was enhanced. Therefore, the MTIW can be considered as a promising technique for improvement but extensive research is still required.

Effect of Magnetopriming on Photosynthetic Performance of Plants

“…Exposure to a MF could be useful to enhance plant growth and productivity in addition to overall biomass production, and improvement also affected metabolic substances such as plant photosynthetic pigments. In fact, this better photostimulation and growth can be explained by improving ion uptake and mobilization under a MF [28]. In contrast, plant growth and productivity are generally controlled depending on photosynthetic pigments [29].…”

“…In contrast, plant growth and productivity are generally controlled depending on photosynthetic pigments [29]. Indeed, MFs are known to promote biochemical changes and could be used as a tool to stimulate growth and responses, including photosynthetic pigments such as chlorophyll and carotenoids [30]. A SMF showed a simulative effect on pigment content (carotenoids, chlorophyll a, b, and total pigments), whereas carotenoids and chlorophyll a were more affected than chlorophyll b [19].…”

Irrigation with Magnetized Water Affects the Soil Microenvironment and Fruit Quality of Eggplants in a Covered Vegetable Production System in Shouguang City, China

“…Tombuloglu et al (2019) showed that magnetic nanoparticles impact the absorption of plant nutrients and that a certain intensity of magnetic nanoparticles can lead to an increase in the iron (Fe), neodymium (Nd), and cobalt (Co) contents of leaves (p < 0.005). Moreover, due to the positive effects of a magnetic field in improving the soil environmental conditions (Taimourya et al 2018), the crop yields, plant height, leaf area, PS II efficiency, and photosynthesis rates were improved when the irrigation water was exposed to a static magnetic field under greenhouse conditions (Kataria et al 2017). Additionally, irrigation treatment using MW could be conducive to promoting plant reductase activity and biomass accumulation by reducing the negative impact of water stress on plant growth (Baghel et al 2018).…”

Etude de l’effet de l’irrigation avec des eaux magnétisées sur la croissance, le rendement du piment et la salinisation du sol dans un environnement aride

“…Cette augmentation traduit l'effet de traitement magnétique sur l'amélioration de la qualité de fruits de la culture du piment. Taimourya et al (2015) ont, également, signalé l'importance de l'effet magnétique sur l'amélioration remarquable de la qualité des tubercules. En ce qui concerne le nombre des fruits par plante, pour la première cueillette, les traitements magnétiques par l'appareil Magiko et Témoin sont significativement différents entre eux à un seuil de 5%.…”

“…En effet, les travaux de recherche ont été orientés en grande partie vers l'effet du traitement magnétique de l'eau sur la croissance et la physiologie des plantes, ainsi que le rendement en termes de quantité et de qualité (Esmaeilnezhad et al, 2017;Fakhri et al, 2018 ;Yano et al, 2004 ;Nasher, 2008 ;Hameda, 2014 ;Elaoud et al, 2016). D'autre part, des études récentes ont rapporté que l'eau magnétisée peut augmenter la productivité de l'eau et diminue le risque de salinisation des sols à travers la réduction de la taille des cristaux des sels de façon qu'ils deviennent plus absorbés par les racines (Ajitkumar, 2014;Taimourya et al, 2015). Cependant, les travaux sur l'utilisation de ces techniques sont limités dans des conditions où la salinité de l'eau et du sol est relativement élevée.…”
