Electro-osmosis is a method for regulating water availability by utilizing one-way electric current directly. Two electrodes are installed on the ground and run by electricity, then the water contained in the soil will move from the positive electrode to the negative electrode. Water is a resource and a determinant factor that determines the performance of the agricultural sector. Water scarcity is a major obstacle in the management of dry land. Water maintained by electrodes will facilitate the roots to absorb water by utilizing the principle of electro-osmosis. In this study, we observed the rate of water withdrawal and growth of mustard plants using the electro-osmosis method at various input voltages (5, 12 and 24 volts) and combinations of soil types (clay, compost and sand). The best treatment is the 12 volt input voltage with a combination of dominant clay soil consisting of 40% clay, 30% compost and 30% sand.
