Egypt's agricultural sector is facing a major challenge to produce more food with less amounts of water, especially under scarcity of water locally and internationally. Agricultural sciences take an interest not only in the common and valued crop-forming factors, but also in those less expensive and generally underestimated, though more pro-ecological ones, such as ionizing, laser or ultraviolet radiation and magnetic fields. The water treated by the magnetic field or pass through a magnetic device called magnetized water. There have been many investigations on the effects of low frequency electric and magnetic fields on plants. It has been shown that a magnetic field (MF) has effects on the normal functions of living things. A magnetic field was shown to induce seed germination, reproduction and growth of the meristic cells and chlorophyll quantities, plant growth and development, the ripening, yield and quality of different crops. Moreover, data recorded from these studies showed that, decrease of soil alkalinity, increase in mobile forms of fertilizers and reduction of scale in irrigation pipe. So, use of magnetic technology in agriculture is considered to be one of the non-conventional technology, economic, safe healthy and environmentally and promising to improve productivity of various crops and water use efficiency. Therefore, this technology has been developed and subsequently used widely in the field of agriculture in many countries such as (Russia, Australia, USA, China and Japan). Desperate its importance, it is not yet explored in Egypt.
Our experiments whether published or under publication recorded that irrigation plants with magnetic water under field conditions in Nubaria, Wadi El-Natorun and Ismailia regions tended to improve growth, metabolism, quality and productivity of tested crops (wheat - barley and maize as grains, faba bean - lentils - chickpeas � ground nut, soybeans, mungbean as legume, sunflower - flax and canola as oil, sugar beet as one of the sugar crops and potatoes as vegetable crops). These increases ranged from 8.25 to 42.00% in economic yield (ton/fed.) according to the crop. Similar trend was recorded for water use efficiency. As well as, the results showed significant increase in quality attributes (protein, oil, carbohydrates, sugar, macro and minor elements, fatty acids and amino acids contents) according to type of plants. It was also observed significant increases in yield of barley, flax and safflower plants grown under salt stress conditions (either in the water or soil) in the area of Wadi Natroun. In a short preliminary biological study a conclusion emphasized that the magnetic water hasn't any side effects or complications in the biological system.
