Évaluation de la productivité du chou pommé (Brassica oleracea), sous l’effet de l’irrigation avec une eau traitée magnétiquement, dans la région de Casablanca (Maroc)

Treatment of water by a static magnetic field showed positive effects such as stimulation of growth and the improvement of the production of plants, while respecting the environment. To quantify the effect of the application of this technology on crop production in Moroccan production conditions, an field experiment was conducted during 2 years (2012-2013) on a farm located in the Chaouia-Ouardigh region. Cabbage plants (Brassica Oleracea), irrigated by magnetically treated water were monitored through measurement of growth and production parameters (height, circumference, weight and yield). Analysis of the results showed a persistent and highly significant improvement through an increase in height in the order of 27.3% and 26.1%, an increase in the circumference of 22.7% and 19.3%, a gain in weight of 27.9% and 24.3% and an increase in yield of 28.9% and 22.9% respectively for the two seasons. This affordable technology opens the way for specific treatments using the electromagnetic properties of the water.
