| Abstract | ||
| The increasing production of agricultural products with high efficiency has led to the use of new methods to increase the yield of these products. Among others, we can mention vertical cultivation in greenhouses with artificial light. In these greenhouses, in addition to controlling the different climatic parameters, the light needed by the plant is provided by low consumption LED lamps. The ability to grow all kinds of agricultural products, including lettuce and other vegetables, by changing the height of the floors and changing the spectrum of different lights effective in the photosynthesis of plants is one of the capabilities of this greenhouse. In this research, a greenhouse with vertical cultivation was built with artificial light through LED lamps, irrigation systems, ventilation and hydroponic cultivation bed for growing plants. Due to the independence of the floors, it is possible to cultivate different crops with the same nutrition at the same time, and in addition to light, other variables such as temperature and humidity can also be controlled. The performance results showed that after 30 days and with dimensions of one square meter, 72 lettuce plant were harvested from the system, which is comparable to the yield of field and greenhouse production methods. Greenhouse evaluation was done in 3 treatments with different light combinations. The lowest fresh and dry weight of the plant was observed in the combination of red, blue and far red light treatment, and red light had the highest yield compared to the far red and red, blue treatments. | ||
