The Effect of Irrigation by Magnetically Water on Chlorophyll and Macroelements uptake of Pepper (Capsicum annuum L.).

Magnetic field is known to induce biochemical changes and could be used as a stimulator for growth related reactions. Pepper plants were irrigated with water passed through magnetic device with its magnetic field in the range of 3.5-136 mT for magnetic treatment of irrigation water. Results indicated that, irrigation with magnetic water induce positive effect on all studied parameters such as chlorophyll content, carbohydrate and tissue content of protein especially in the third week of harvest. On the other hand, the essential elements (N, P, K) uptake was significantly increased as compared with plants irrigated with tap water. Thus, the present results have shown that irrigation with magnetic water can be considered as one of the valuable modern technologies that can assist in saving irrigation water, enhance growth, and nutrient uptake of pepper under green house conditions.
