Objectives: The present study was conducted to investigate the effects of light and carbon dioxide on the quality and yield of basil plants.
Materials and Methods: In this experiment, the effect of three concentrations of carbon dioxide Contains 350, 750, 1500 mg/liter and artificial light at three levels of 78, 156, and 234 μmol/s on the properties of basil plants was investigated.
Results: The results showed that the increase in light intensity and carbon dioxide concentration led to a significant increase in the leaf area, plant height, shoot fresh and dry weight (shoot biomass), number of leaves, chlorophyll content, carotenoids, nitrate accumulation rate, the percentage of dissolved solids and nitrogen absorption. In this way, in the treatment of 1500 mg/liter of carbon dioxide with 234 μmol/s of light, the amount of dry weight, wet weight, carotenoids, chlorophyll, plant height, surface and number of leaves and nitrogen were increased 280, 100, 160, 123, 100, 163, 128 and 24 % respectively. In the light treatment of 156 μmol/s and carbon dioxide 1500 mg/liter, the amount of dissolved solids increased by 76%. Also, in the light of 234 μmol/s and carbon dioxide of 500 mg/liter, nitrate increased by 115%.
