Abstract

Two field trials using canola (var. Serw-6) were conducted to study and evaluate the effects of magnetizing irrigation water on Canola vegetative growth, photosynthetic pigments, seed, yield and water use efficiency as well as seed biochemical constituents and fatty acids composition of the yielded oils. Application of magnetizing irrigation water led to marked increases in growth parameters (plant height (cm), fresh weight and dry weight (g plant-1) and water contents (%); photosynthetic pigments (chlorophyll a, chlorophyll b, chlorophyll (a+b), carotenoids and consequently total pigments). Treating plants with magnetized water increased also, seed yield and its components plant height (cm), branches (number plant-1),seed weight (g plant-1), pods (number plant-1), seeds weight (g pod-1), 100-seed weight (g) and seed yield (kg fed-1) as well as seed biochemical constituents (oil (%), oil yield (kg fed-1) macro and micro elements). The treatment improved oil quality as it affected fatty acids composition of canola oil, by increasing total unsaturated fatty acids and total essential fatty acids. Moreover, Water Use Efficiency (WUE) increased significantly as a result of irrigation with magnetic water by 19.05% compared to control plant. The present findings have shown that irrigation with magnetized water could be employed as one of the most valuable modern technologies that can assist in saving irrigation water and improving yield and quality of Canola under newly reclaimed sandy soil. The usage of magnetic water in the agricultural production will enable intense and more quantities and qualitative production.
