Effects of light at different distances and different power on growing Triticum aestivum L. (wheat) and Hordeum vulgare L. (barley)

With this research, an effective method of using artificial light for plant growth has been investigated. Problems such as global population growth and the ongoing climate crisis increase the need for efficient methods for stable food supply. In this study, the effects of grow lamps with 250 W, 400 W, 600 W MH values on barley (H. vulgare L.) and wheat (T. aestivum L.) for different distances of 1m, 1,5 m and 2,5 m were examined. Growing took place without daylight, within light magnification rooms with a value of 250 W, 400W, 600 W MH as the only light source. Plants exposed to light for 13-14 hours daily were harvested after 15 days. In the studies, the amount of the electrolyte leaks, chlorophyll, carotene and intake of B (Boron), Cu (Copper), Fe (Iron), Mn (Manganese), Zn (Zinc), Mg (Magnesium), K (Potassium), Ca (Calcium), (P) Phosphorus from the soil of the 250 W, 400W, 600 W MH lamp after harvest were determined at different distances. While examining the obtained data, a comparison between 250 W, 400W, 600 W MH growth period lamp of wheat and barley samples and tolerance conditions according to different distances was made.
