| Abstract:
The plant productivity and quality could be influenced directly or indirectly by the changes of environmental conditions such as light intensity, daylength, the concentration of carbon dioxide, air temperature and air humidity. These environmental conditions can be controlled properly for crop growth in a plant factory system. On the other hand, in the greenhouse, environmental conditions are considerably affected by outside weather. It has been known that the productivity and quality of peppermint (Mentha piperita L.), one of the most important herbs, are very sensitive to the change of the environment. Peppermint was grown for 22 days in three different plant production systems, greenhouse, plant factory with natural and artificial lighting and, closed plant factory with artificial lighting. Fresh and dry weight were higher in the two plant factory systems than in the greenhouse and the contents of essential oil and vitamin were highest in the closed plant factory system than in the other plant production systems. | |
