Hydroponics is ideal for improving tomato quality, increasing yields, and escaping insects and/or disease. From a view point of these
advantages, a tomato hydroponic system is highly recommended. Fertilizer application dosage and methods affect plant growth, yield and
tomato quality. Potassium accelerates lycopene accumulation, and selenium increases fruit firmness. Chlorine and silicon increase soluble
solid contents. Tomatoes contain various food functional substances such as lycopene, -
-carotene, ascorbic acid, tocopherol, etc. The
kinds of salts and their concentration in nutrient solution affect fruit texture, the amount of minerals, lycopene, and food functionality.
Food functionality of tomatoes is well known to consumers, having antioxidants that prevent cancer and heart disease. In this manuscript
we review the benefits of hydroponics on tomato quality, with a focus on Korea.
