Abstract
Recently silicic acid has been attracting attention as a highly useful tool for crop production. Although zeolite mainly composed of silicic acid is often used as a part of culture soil, few studies have been reported the effect of silicic acid application on initial growth of vegetables. We examined the influence of zeolite application on spring seedlings of seven vegetables (kidney bean, chile pepper, lettuce, broccoli, cabbage, tomato, and eggplant). The results revealed thickness of the stems, leaf colors, and roots spread of all the vegetables except for lettuce were enhanced by addition of zeolite.
