Impact of Magnetic Water Irrigation for Improve the Growth, Chemical Composition and Yield Production of Broad Bean (Vicia faba L.) Plant

Abstract

Magnetic water is considered one of several physical factors affects plant growth and development. Magnetic water fields are known to induce biochemical changes and could be used as a stimulator for growth related reactions. The seeds of broad bean (Vicia faba, L. cv. Giza 3) were irrigated with water passed through magnetic device (Magnetic Funnel - MAGNETIC TECHNOLOGIES DUBAI, UAE, LLC. PATENT No. 1826921). Two pot experiments were conducted during season 2010-2011 at greenhouse to study the impact of magnetized water on growth, some chemical constituents and yield productivity of broad bean plants. The stimulatory impact of magnetic water may be ascribed to the increasing of plant growth (plant height, leaf area, leaves, stems, roots fresh and dry weights) and yield production, which increase absorption and assimilation of nutrients. It appears that irrigation with magnetic water may be considered a promising technique to improving the growth and water content of broad bean plant. Magnetic water treatment could be used to enhance growth, chemical constituents (chlorophyll a and b, carotenoids, total available carbohydrates, protein, total amino acids, proline contents, total indole, total phenol, GA3, kinetin, RNA, DNA,) and inorganic minerals (K+, Na+, Ca+2 and P+3) contents in all parts of broad bean plant under greenhouse condition. Results indicated that, irrigation with magnetic water induced positive significant effect on all studied parameters
