The Use of Desalinated Seawater from a Solar Still Favors the Growth and Yield of Lactuca sativa L. in a Hydroponics System
The study explored the potential of utilizing the desalinated seawater produced by a solar still as irrigation water to a hydroponic vegetable production system. A field experiment was laid out in Randomized Complete Block Design to compare the growth and yield of Lactuca sativa L. using the desalinated seawater from a solar still and a tap water. The growth and yield of L. sativa are significantly higher using the desalinated seawater because of the latter's quality that is more suitable to plants' requirement in hydroponics. The desalinated seawater does not contain a significant amount of minerals that would react with the hydroponic fertilizer and would eventually reduce the availability of nutrient elements for plant growth and nutrition. Higher yield of the plant in hydroponics can, therefore, be achieved using desalinated seawater from a solar still.
