Abstract
A great attention on the possibility of using magnetized water which has very affective effects on germination, plant growth and production. Our previous and positive results on many crops i.e., wheat, lentil, chick-pea, faba bean, flax, canola and sugar beat, led us to continue studying the application of magnetic treatments either seeds and/or water on productivity of field crops under field condition. In this study, two macro field trials using potato (var. Spunta) were conducted at Research and Production Station, National Research Centre, Alemam Malek village, Al Nubaria district, Al Behaira Governorate, Egypt in 2012/2013 and 2013/2014 winter seasons to study and evaluate the impact of magnetizing irrigation water on quantity, quality and anatomical structure of potato plant. Results indicated that, irrigation potato plants with water passed through magnetic device (Magnetron, 2 inch, production by Magnetic Technologies L.C.C. company, Russia, branch United Arab Emirates) induced positive significant effect on the most of studied parameters (anatomical structure of leaves, stem and tuber, tuber physical properties, yield components, yield and some macro and micro elements and carbohydrates fractions) compared with irrigation with normal water. The percent of increase in tuber yield per fed (fed=4200 m(2)) reached to 33.25%, ranged from 0.71 to 20.95 % in yield components parameters. Regarding nutritional value, the increment ranged between 2.40 to 28.57% and from 2.19 to 33.92% in macro (N, P, K, Ca & Mg) and microelements (Fe, Mn, Zn & Cu), respectively. The percent of increases reached to 7.81, 11.56 and 5.13% in the total carbohydrates, polysaccharides and starch, respectively. It could be concluded that, magnetic water treatment could be used to improve productivity of potato tuber under newly reclaimed sandy soil condition.
